Identifying Basic Drill Bits The Drill Doctor® Sharpening Process The Drill Doctor is most efficient when used to sharpen a drill bit’s original point angle. With its standard Diamond Sharpening Wheel it will sharpen high-speed steel, cobalt, TiN-coated, carbide and masonry drill bits. The sharpening process includes 4 easy procedures: It has been designed and engineered to sharpen three of the most common drill bit types and offer you an ability to customize your point: Standard Point This general-purpose point is used for drilling softer materials like cold rolled steel, aluminum, and wood. Split Point Split-point bits are self-centering and are generally used for tempered steels, hard alloys or hard cast materials. Masonry Bits Masonry bits have a carbide insert at the point and are used for drilling materials like cement, brick, and ceramic. It is important to understand that each bit has a all of these characteristics. When viewing a well-sharpened bit from the end, the entire surface from the Cutting Edge to the Heel will have a finely ground surface without ridges or indentations. The Heel will always be lower than the Cutting Edge. www.drilldoctor.com

1. Determine the type and angle of the drill bit.

2. Align the bit in the Chuck.

3. Sharpen the bit.

4. Split the point (if you choose).

Be sure to complete the first three procedures in order to sharpen a bit; and always sharpen a bit prior to splitting it. Choosing Your Drill Bit Point Angle When drilling into certain difficult materials, a shallower point or 135° point angle produces a better-finished hole. Your Drill Doctor allows you to sharpen bits with either the standard 118°or the flatter 135° point angle. You can also adjust the “chisel and relief angle.” (Refer to page 19 for the benefits of using Variable Alignment to adjust the Chisel and Relief angles.) Depending on the material you are drilling in, you may choose to increase or decrease these angles. On the Model 500X

Check your drill bit angle Most bits are 118° or 135°. Hold your bit point up to the key to the left to see which type your bit looks like. If you can’t tell due to small size or damage on the tip, set your Drill Doctor based on the application. Most wood and soft metal applications should use 118 degree. Harder materials such as stainless steel and tool steel should use 135° or if you are drilling contoured materials such a car fender and plan on splitting the point. www.drilldoctor.com

Point Angle Adjustment Knob Choose the angle Loosen the Point Angle Adjustment Knob on the right side of the Sharpening Port and slide the metal Point Angle Adjustment Plate to either the standard 118° or the flatter 135° point angle. Then re-tighten the Knob. Insert bit in Chuck and tighten

On the Model 750X Point Angle Adjustment Knob Choose the angle The Model 750X has additional advanced features that enable you to fine-tune your bit geometry. Loosen the Point Angle Adjustment Knob to the right of the Sharpening Port and slide the metal Point Angle Adjustment Plate to 118°, 135° or the custom angle of your choice. Choose your point angle based on the application you’re drilling. Then re-tighten the Knob. Aligning the Drill Bit This makes sure that the Drill Doctor creates the right geometry. And, it sets the bit so that only a small amount of the tip is taken off. See page 17 to align and sharpen a Masonry drill bit.)

Insert the bit into the Chuck Jaws and close the Jaws just to the point where the bit slides in and out. Do not over tighten the Chuck; the bit needs to be able to move in and out until Step 4. (Model 750X users refer to “Using the Variable Material Take-Off (MTO)” on page 20.) A good test to see if the Chuck is tightened the correct amount is to make sure it moves when you pull on it with your fingers, but will not fall out when you turn the Chuck upside down. Alignment Button Insert Chuck into Alignment Port Press the Alignment Button down and hold it. Match the either of the Alignment Guides on the Chuck with the 118° Notch on the Alignment Port. Insert the Chuck. While holding the button down, slide the drill bit Drill Bit 118° forward until it touches Alignment Stop Guide the Drill Stop and the Chuck is pushed all the way into the Alignment Port. Release the Alignment Button. If you are using a Model 750X and have chosen a custom bit point (between 115° and 140°), start your alignment in the closest setting to the point angle you are using. (For example, if you are setting the point angle below 118°, than set the alignment in the 118° setting.) Refer to “Using the Variable Alignment to Adjust the Chisel and Relief Angle” on page 19. www.drilldoctor.com

Adjust Bit Position Look at your bit and make sure the Clamp Arms are in the bit’s narrowest spot. If they aren’t, turn the bit in the chuck so that it is held by the Bit Clamp Arms at the narrowest width. This is important because this setting determines the angle at which your bit will be sharpened.

• You will hear a grinding noise (zzzzzzzzz) as you complete each half-turn and each side of the bit face is ground.
• The Chuck will rock as you turn it and the Cam rides on the Guide.

Turn the Drill Doctor on. Align either of the Sharpening Guides with the Cam Guide on the machine. Cam Tighten Chuck Hold onto the Chuck and tighten the Chuck Knob. (Avoid over-tightening the Chuck in the Alignment Port. This could damage the Chuck and Port.) Cam Guide Insert Chuck and turn until the bit is sharp

• Only light pressure is required. Insert the Chuck in the Sharpening Port. Making sure you keep the Cam against the Cam Guide, rotate the Chuck one halfturn in a clockwise direction—from Sharpening Guide to Sharpening Guide—an even number of times. Your motion should be smooth and even. To sharpen both sides of the bit evenly, always use an even number of half-turns. The number of turns needed to sharpen the bit depends on the size. Turn the Chuck an even number of half-turns with light inward pressure:
• 3/32-inch bits—use 2 to 4 half-turns,
• 1/8-inch bits—use 4 to 6 half-turns,
• 3/8-inch bits—use 16 to 20 half-turns. Note: Use just enough pressure to keep the Cam against the Cam Guide. Let the machine do the sharpening.

Remove and re-tighten Press the Alignment Button and remove the chucked drill bit. Tighten the Chuck once more to ensure the bit won’t move when you sharpen it. You are now ready to sharpen the drill bit. Sharpening the Drill Bit Before sharpening you should know:

• Keep the Cam in contact with the Cam Guide as you sharpen—push the Chuck straight into the Port. www.drilldoctor.com

Identifying Correctly Sharpened Drill Bits (and what to do with those that aren’t!) Correctly Sharpened Bits Heel Chisel Point Cutting Edge The entire surface from the Cutting Edge to the Heel will have a finely ground surface without ridges or indentations. The Heel will always be lower than the Cutting Edge. The Chisel Edge will be clean and straight. Incorrectly Sharpened Bits Problem Cause The Chisel Edge is ground flat. Chuck Jaws did not grip drill bit properly in the aligning process (Page 8). Problem Insuffecient (Negative) relief or a slow cutting drill bit. Cutting Edge Heel Relief Angle Problem Bit backing out or slipping out of the jaws when you are sharpening Problem The Chisel Edge is not clean or straight. Cause The bit isn’t completely ground yet. Solution Continue sharpening the bit until the chisel is clean and straight. If the machine quits removing material before the chisel is clean, realign and sharpen again. (Model 750X users can increase or decrease MTO (material take-off) to speed up this process.

www.drilldoctor.com Drill bit alignment. Solution Re-align the drill using the Adjustable Alignment procedure on page 19. To increase relief, insert the alignment guide on the chuck closer to the (+) side of the alignment port, then sharpen the bit. Cause Chuck too loose or too much pressure when sharpening. Solution Use more torque when tightening the Chuck or less pressure when sharpening. Clean the Chuck w/ compressed air if the problem persists. Solution Realign the bit by carefully following steps 1 through 5 on Pages 8 to 10. Cause Split Points Split point drill bits prevent walk-around on the material before they begin to cut. This feature is described as self-centering. The need to center punch is effectively eliminated. A standard drill bit chisel point has to wear an area in the middle of the hole to be drilled before the cutting edges will remove material. Due to its additional cutting lips along the chisel edge, a split point will begin cutting immediately. Up to 70% less thrust (when compared to a non-split or conventional point) is required to drill a hole with a split point. www.drilldoctor.com

Creating or Replacing a Split Point Identifying Correctly Split Drill Bits (And What to Do With Those That Aren’t!) Leave bit in Chuck after sharpening

Always align and sharpen a bit before splitting it. To split the point, do not remove the bit from the Chuck after sharpening.

Splitting Guide Sharpening Guide

Align Guides Align one of the Sharpening Guides on the Chuck (short white marks) with the Splitting Guide on the Splitting Port. Make sure the Alignment Guides insert into the Split Point Guide Rails in the Splitting Port. Split the point Press Chuck slowly and firmly into the Splitting Port until it stops. Remove the chuck, rotate one-half turn, and repeat. Correctly Split Split lines are nearly straight across. Split line Undersplit Solution Split lines do not meet in the center but Chisel Edge remains. More grinding is needed for larger drill bits. If one side of the bit is undersplit, insert the Chuck into the Splitting Port again and split both sides. Push the Chuck into the Port until it stops. Repeat until the split sides are equal and look like the correctly split bit shown above. Not enough material has been removed from the Heel of the drill bit. Oversplit Solution Too much material removed. Split lines are joined in the center and Chisel Edge has been removed. Reinsert the chucked bit into the Sharpening Port and remove enough of the tip until the split tip looks like the correctly split bit above. Check the tip of the bit carefully to determine that both sides of the bit are split equally. Compare it to the illustrations. If it does not match, study the information following.

www.drilldoctor.com www.drilldoctor.com

Grit Tube Attachment The Grit Tube attachment is designed to keep any sparks caused by sharpening safely inside the machine and away from you. In addition, the Grit Tube reduces the sharpening dust in the air and on your workbench. Simply insert the Grit Tube into the Splitting Port of your Drill Doctor when sharpening. It will catch the grit that is formed from the sharpening process. Clean the inside of your Drill Doctor and the Grit Tube on a regular schedule. The grit tube is designed to accept a standard 1” shop vacuum for extended periods of sharpening. Sharpening Bits of Different Lengths, Diameters, and Types Drill Bits Of Different Sizes Too many rotations of a small-diameter bit may result in incorrect sharpening and too few on a large bit may not sharpen enough. Continue to sharpen until the Chisel Edge is clean and straight and the entire surface from the Cutting Edges to the Heel is finely ground.

• 3/32-inch bits—use 2 to 4 half-turns,
• 1/8-inch bits—use 4 to 6 half-turns,
• 3/8-inch bits—use 16 to 20 half-turns. Large Drill Bits The Model 500X sharpens bits from 3/32” to 1/2”. (You can also purchase a Large Bit Chuck that sharpens bits up to 3/4”.) The Model 750X comes equipped with that Large-Bit Chuck. It sharpens bits from 3/32 to 3/4 inches. Bits 1/2” or larger will need a minimum of 40 half turns. A 3/4” bit may require up to 60 half turns. It may take two or three complete sharpenings (repeat all steps) to resharpen a very dull or chipped large drill bit. Your Drill Doctor is delivered with a 180-grit Diamond Sharpening Wheel. If you regularly sharpen larger bits between 1/2” and 3/4”, you may wish to purchase the coarser 100-grit Diamond Sharpening Wheel, which sharpens larger bits faster. Short Drill Bits and Bits Smaller than 1/8” Set the point angle for 118°. Put the bit in the Chuck as normal, but tighten Chuck so that it is just snug enough for the bit to move freely. Push and hold the Alignment Button. Partially insert the Chuck in the Alignment Port, but do not push the Chuck all the way in. Use the Chuck Knob to rotate the bit until it can be held by the Bit Clamp Arms in the narrowest width of the bit. Make sure that the bit is touching the Drill Stop, then release the Alignment Button. Turn the Chuck until the Alignment Guide on the Chuck aligns with the 118º notch on the Alignment Port. Now, push the Chuck the rest of the way in. Tighten the Chuck, remove, and tighten again. Sharpen the small bit as usual. Aligning and Sharpening Masonry Drill Bits To sharpen a masonry bit, you do not turn the Chuck. Instead you insert the Chuck until it touches the wheel, remove, and repeat on the other side.

Set the point angle to 118°. Large bits are sharpened just like any other bit. It is important to sharpen these bits so that the entire face of the drill bit is sharpened. A large bit requires more pressure and will require more half-turns to sharpen it.

Masonry Sharpening Marks

Align the bit with the Masonry Sharpening Marks Insert the bit into the Chuck and line up the carbide insert on the tip of the bit so that it is parallel to the Masonry Sharpening Marks on the end of the chuck. Leave about 1/2”-5/8” of bit sticking out past the nose of the chuck. Tighten the chuck just to the point that the bit slides in and out. Set the depth Cam Set the depth by lining up the Sharpening Guide with the Cam Guide. Push the Chuck into the Sharpening Port until it stops and tighten the Chuck. Remove the Chuck to ensure the carbide insert is aligned with the Masonry Sharpening Marks and tighten again. Using the Variable Alignment to Adjust the Chisel and Relief Angles Both Models 500X and 750X enable you to adjust the Chisel and Relief Angles of your drill bit. The Chisel and Relief Angles have a direct effect on the performance of your drill. By increasing the Relief Angle, you can increase the speed of the drill in softer materials. To improve the quality of the hole you can adjust the drill to be less aggressive. A less-aggressive drill has a lower Chisel and Relief Angle. Your Drill Doctor enables you to adjust both angles in one setting.

To prepare your bit for this fine adjustment, follow all the Steps for chucking your bit given previously in this User’s Guide.

Sharpening Guide Sharpen by “plunging” Line up the Sharpening Guide on the Chuck with the Cam Guide on the machine. Plunge Cam the Chuck into the Sharpening Port until it touches the Sharpening Wheel. Remove the Chuck, rotate one half-turn clockwise and repeat the plunge action. Start with four plunges and always use an even number. Inspect the bit and continue until the cutting surfaces are sharp. If the bit stops grinding before the edges are sharp, loosen the Chuck, push the bit out slightly. Make sure carbide insert is still aligned with Masonry Sharpening Marks. Tighten the Chuck, and continue sharpening. Cam Guide

www.drilldoctor.com Insert Chuck into Alignment Port To adjust the Chisel and Relief Angles, simply align the bit as usual with the following adjustment; Cam Guide

Chuck bit as usual Alignment Port 118° To increase Relief—position the Chuck in the Alignment Port so that the Alignment Guide is closer to the (+) position. This will make a more aggressive drill point. To decrease Chisel and Relief—position the Chuck in the Alignment Port so that the Alignment Guide is closer to the (-) position. This will make a more precise hole. Take care not to adjust Relief too far as this will actually cause the drill to lose all Relief and therefore not drill a hole. Each notch in the Alignment Port is approximately a 10° change in Chisel Angle. www.drilldoctor.com

Adjust bit position, tighten Chuck, and sharpen as usual Refer to pages 9-10 for these Steps. Experiment with a few different settings to find the one that best suits your drill bits and application. You may find it helpful to mark this setting for future use. Questions and Answers

1. Question:

Why was my drill bit sharpened improperly? Answer: The most common cause of improper sharpening is drill bit alignment. Key causes are:

1. Chuck not pushed all the way into the Alignment Port.

Using the Variable Material Take-Off (MTO) Variable Material Take-Off Knob The Model 750X enables you to remove more or less material from the tip of your bit when you sharpen. If your bit is only slightly dull and you simply wish to “touch up” its point, turn the Material Take-Off Knob clockwise to reduce the amount of time it takes to sharpen the bit. If your drill bit is quite dull or damaged, turn the Material Take-Off Knob counter-clockwise to increase the amount of material removed. Your MTO adjusts from 0 to .040 of an inch in increments of .005. Prior to aligning the bit, turn the MTO Knob counter-clockwise until it stops. (This is the maximum material that can be removed in one sharpening.) Then turn it clockwise 3 marks on the MTO knob. This is a good place to start for most bits. Now turn the MTO knob either direction to adjust the desired MTO. Each mark on the MTO knob is equal to .005” change in material removed from the bit. Note: After you have sharpened your bits on the Drill Doctor at least one time, it is desirable to turn the MTO Knob such that only a small amount of material is removed from the bit each time you sharpen. This will significantly decrease the time to sharpen as well as extend your bit and wheel life. Once you’ve made your adjustment, align and sharpen your bit as usual.

2. Drill not aligned in the Chuck Jaws correctly.

3. The type of drill requires an angle adjustment to

achieve the desired Chisel and Relief Angles. Try using the Variable Alignment to adjust the Chisel and Relief Angle (see page 19).

4. Chuck is dirty or the bit slipped out of alignment. See

pg 25, “Cleaning the Chuck.”

5. Too many rotations of a small-diameter bit results in

incorrect sharpening, and too few on a large bit may not sharpen enough. See page 16, “Drill Bits of Different Sizes.”

2. Question:

When I aligned the drill bit and sharpened it, why was no material removed? Answer: This happens when the bit is not protruding out of the Chuck far enough. You may have allowed the Alignment Button to knock the drill back into the Chuck when aligning the bit. Carefully realign the bit in the Alignment Port again. Make sure the drill bit is pushed all the way against the Drill Stop before you release the Alignment Button

3. Question:

I sharpened the bit. Why will it not cut? www.drilldoctor.com

6. Question:

This happens when the Heel on the bit is higher than the Cutting Edge (negative relief). To correct this problem, follow the instructions in “Using the Variable Alignment to Adjust the Chisel and Relief Angle” on page 19. Why is the chisel edge on my drill bit flat? You may have a specialty drill bit. Slow and Fast Spiral, Helix, Turbo Flutes, and Raised Margin drill bits are considered specialty bits. If you’re are getting insufficient relief on specialty bit types, try aligning all the way in the (+) setting on the alignment port. This will help improve the sharpening on these types of bits. Answer: During the alignment process the Bit Clamps were gripping the high points of the drill bit. Realign the drill bit making sure that the Bit Clamps are located in the narrowest section of the bit. See page 10.

7. Question:

Why was my drill bit sharpened improperly?

4. Question:

What can I do about flat spots on the bit point between the Cutting Edge and the Heel? Answer: Answer: The most common cause of improper sharpening is improper drill bit alignment. Key causes are: The flat spots on a sharpened bit are the result of an incomplete or paused half-turn of the Chuck in the Sharpening Port. To correct, apply light, inward pressure and rotate the Chuck smoothly while sharpening. Be sure to complete the half-turns.

5. Question:

1. Drill point not pushed all the way to the Drill Stop.

2. Chuck not pushed all the way into the Alignment Port.

3. Drill not aligned in the Bit Clamps correctly.

In order to correct these problems be sure the Chuck is all the way in the Alignment Port. The drill point must be against the Drill Stop and the Bit Clamps must be at the narrowest part of the drill bit. Why is the drill point off center?

8. Question:

Answer: If the tip of the drill bit appears to be sharpened off center, check the following items:

• You may not have done an even number of half-turns when you sharpened and one face of the bit was ground more than the other. Always use an even number of half-turns when you sharpen.
• Make sure that there are no particles between the Chuck Jaws and the drill bit that could hold it off center. Check the drill to ensure it is straight and free of burrs.
• Make sure the bit is not loose in the Chuck.
• During the sharpening process be sure to keep the same pressure on each half-turn.

www.drilldoctor.com Why is my split point uneven? Answer: Page 15 shows a drill point that is undersplit and a drill point that is correctly split. To correct an uneven point split, insert the Chuck into the Splitting Port and split both sides again. Push the Chuck into the Port until it stops. Repeat until the split sides are equal and look like the correctly split bit shown above. www.drilldoctor.com

9. Question:

Cleaning Your Drill Doctor Why does the drill bit back up into the Chuck during the sharpening procedure? With the Drill Doctor unplugged, shake accumulated drill bit grinding dust from behind the Wheel Cover into a disposable container. Remove dust particles around the wheel with a small, dry brush. Dispose of the container and drill bit dust in a safe and environmentally approved manner. With a dry cloth wipe the inside and outside of the Sharpening Port to remove any grinding dust that may have accumulated. A standard 1" vacuum hose works equally well. You can also use the Grit Tube attachment as shown on page 16. Answer: Make sure the bit is tight in the Chuck before sharpening. Your Chuck may be dirty. Follow the steps for cleaning the Chuck on page 25.

10. Question:

When splitting, why don’t I hear a grinding sound? Answer: The Chuck is not seated properly in the Splitting Port. The Chuck’s Sharpening Guide must line up with the Splitting Guide on the top of the Split Point Port. Firmly and slowly push the Chuck into the hole until the grinding sound stops.

11. Question:

Can I change a 135° drill bit into a 118° drill bit? Answer: You can change the degree angle of any drill bit from 135° to 118°. The alignment and sharpening procedure will need to be performed three or more times to remove the old angle and produce the new angle desired. Drill Doctor Maintenance After sharpening 20 to 25 drill bits, the drill bit grinding dust will accumulate in the grinding compartment. Grinding particles will promote wear in the Sharpening Port and Chuck, so cleaning on a consistent basis can add life to your machine. Before any maintenance or cleaning is performed, be sure to disconnect your Drill Doctor. Removing the Wheel Access Cover Cleaning the Chuck With compressed air, blow out the Chuck from the Knob end or brush out with a small, dry brush. Determining if Replacing the Diamond Sharpening Wheel is Required You can double the life of the Diamond Sharpening Wheel by reversing it before you replace it. The Sharpening Wheel supplied with the Drill Doctor is designed to give you long and trouble free service, with an average of more than 200 sharpenings for 3/32" to 1/2" drill bits. The Diamond Sharpening Wheel may need to be changed if:

• Sharpened drill bits burn or turn blue no matter how fast or slow you rotate the Chuck.
• When touching the Sharpening Wheel (with the machine unplugged), the lower portion feels too smooth (nonabrasive).
• When sharpening the drill bit, it takes too many halfturns to sharpen. Contact the store or dealer where you purchased the Drill Doctor, or contact Drill Doctor directly, to purchase a replacement Sharpening Wheel. With the Drill Doctor unplugged, use your nail or the tip of your finger to pull the Wheel Access Cover down. It will come completely off for easy access. To close, insert the Cover in the slots and snap it back into place.
