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 Model 350X has been designed and engineered to sharpen the most common drill point types: The sharpening process includes 2 easy procedures: Standard Point This general-purpose point (normally 118°) is used for drilling softer materials like cold rolled steel, aluminum, and wood. Masonry Bits

1. Aligning the bit in the Chuck.

2. Sharpening the bit.

Aligning the Drill Bit This makes sure that the Drill Doctor creates the right geometry. It also sets the bit so that only a small amount of the tip is taken off during sharpening. (See page 12-13 to align and sharpen a masonry drill bit.)

Insert bit in Chuck. White Triangle Masonry bits have a carbide insert at the point and are used for drilling materials like cement, brick, and ceramic. Hold the Chuck with the White Triangle facing up. Insert the bit into the front of the Chuck, leaving 1/2" of bit sticking out the front. Tighten Chuck slightly. It is important to understand that each bit has a Chisel Edge, a Cutting Edge, a Heel, a Relief Angle, and a Leading Edge. (The Leading Edge will be important in bit alignment.) Leading Edge 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; this is called positive relief. Alignment Finger www.drilldoctor.com

www.drilldoctor.com Tighten the Chuck by turning the Chuck Knob clockwise just to the point where the bit is snug but can still be slid in and out. The Chuck should not be completely tightened until we set the bit depth for sharpening in the next step. Rotate the drill bit in the Chuck so that the Leading Edge of the flute is against the Alignment Finger. This aligns the bit for accurate sharpening. Note: 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.

Set depth of bit and tighten Chuck. White Triangle Cam Guide Sharpening Port

With the machine turned off, align the White Triangle on the Chuck with the Cam Guide. While keeping the Chuck against the Cam Guide on the 350X, insert the Chuck into the Sharpening Port. Push the Chuck all the way into the Port. Align Guides. Turn on the Model 350X. Align either of the Sharpening Guides on the Chuck with the Cam Guide and insert the Chuck in the Sharpening Port. Sharpening Guide Tighten the Chuck Knob while it’s still in the Sharpening Port. Remove the Chuck and make sure it is tight so the bit won’t move when you sharpen it. Cam Guide

Sharpening the Bit Before sharpening you should know: Making sure that the Chuck rests firmly against the Cam Guide, turn the Chuck one half-turn to the right—to the other Sharpening Guide. Turn from Guide to Guide in a smooth and even motion until the bit is sharp. To sharpen both sides of the bit evenly, always use an even number of half-turns. The number of half-turns needed to sharpen the bit depends on its size.

• Keep the Cam in contact with the Cam Guide as you sharpen—push the Chuck straight into the Port.
• Only light pressure is required.
• 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 until sharp. 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.

Identifying Correctly Sharpened Drill Bits (and what to do with those that aren’t!) Problem Heel same height or higher than the cutting edge Correctly Sharpened Bits Heel Chisel Point Cutting Edge Problem The Chisel Edge is ground flat. 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 (positive relief). Solution Carefully repeat the alignment and sharpening procedure, making sure to use light pressure to keep the Cam in contact with the Cam Guide during sharpening. Problem Cause Alignment Fingers did not position the drill bit properly in the aligning process (page 7-8). Bit backing out or slipping out of the jaws when you are sharpening Too much pressure during sharpening, dirty Chuck, or Chuck not tightened enough. Solution Use just enough pressure to keep the Cam in contact with the Cam Guide. If the bit continues to slip, clean the Chuck as described on Page 17. Realign the bit by carefully following steps 1 through 3 on page 7-8. Surface of the bit isn’t smooth and/or heavy grinding sound. Bit is misaligned or the Cam failed to stay in contact with the Cam Guide during sharpening. Cause Solution Problem Cause Cause Too much drill bit is sticking out of the end of the chuck. Solution Realign the bit. During the re-alignment process, be sure to keep the White Triangle against the Cam Guide as you insert the Chuck into the Sharpening Port to set the depth of the bit. The bit should be pushed up inside the Chuck and should rotate slightly as the Chuck is plunged into the Sharpening Port and contacts the Diamond Sharpening Wheel. Push until the Chuck is fully inserted into the Port. www.drilldoctor.com Sharpening Bits of Different Lengths and Diameters 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.

• 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. www.drilldoctor.com

Large Drill Bits Large drill bits (3/8" to 1/2") will require more half-turns of the Chuck. A well-sharpened bit will have a smooth surface from Cutting Edge to Heel. It may take two or three complete sharpenings (repeat all steps) to re-sharpen a very dull or chipped large drill bit. A 1/2" bit will need a minimum of 20 half-turns.

Plunge until sharp. Tighten the Chuck while checking that the insert is touching the end of the Alignment Fingers. Tighten until the bit no longer moves in the chuck Short Drill Bits The new Chuck design on the 350X enables you to sharpen short bits as easily as longer ones. Simply align the bit in the Chuck as normal. Then sharpen the bit using very light pressure and fewer half-turns. The bit should only briefly contact the Sharpening Wheel. Note that it is OK for the Chuck Fingers to come into contact with the Sharpening Wheel. This will not damage the Chuck. White Triangle Cam Guide 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. Chuck the masonry bit.

Align the White Triangle on the Chuck with the Cam Guide on the machine. Plunge the Chuck into the Sharpening Port until it contacts the Sharpening Wheel. Remove the Chuck and rotate one half-turn to the opposite White Triangle. Plunge the Chuck into the Sharpening Port again to sharpen the other side of the carbide insert. Start with four plunges. Inspect the bit. Then sharpen more if needed. Insert your masonry bit in the Chuck in the same manner as other bits, but in this case, make sure the carbide insert is touching the end of the Alignment Fingers as shown.

Questions and Answers Answer:

1. Question:

This happens when the Heel on the bit is higher than the Cutting Edge (negative relief). Realign the drill bit and resharpen in the Sharpening Port. Why was my drill bit sharpened improperly? Answer: The most common cause of improper sharpening is improper drill bit alignment. Key causes are:

1. Chuck not pushed all the way into the Sharpening

2. Drill not aligned in the Alignment Fingers correctly.

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

page 17, “Cleaning the Chuck,” to correct.

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 11–12, “Drill Bits of Different Sizes.” In order to correct these problems be sure the Chuck is all the way in the Sharpening Port with the Guides correctly matched up.

2. Question:

When I aligned the drill bit and sharpened it, why was no material removed?

• You may have a specialty drill bit. Slow and fast spiral, helix, turbo flutes, and raised margin drill bits are considered specialty bits. Your Drill Doctor does not sharpen these types of bits.
• Follow the normal sharpening procedure. You may have to realign and sharpen more than once to ensure that the bit is sharpened correctly. If the problem persists contact the Technical Service Department.

4. Question:

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

• You may not have completed an even number of halfturns 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 the Chuck is clean.
• 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. Answer: This happens when the bit is not protruding out of the Chuck far enough. The Chuck may not have been tightened enough and the bit may have slipped in the Chuck. Carefully realign the bit in the Chuck and set its depth in the Sharpening Port again.

5. Question:

What can I do about flat spots on the bit point between the Cutting Edge and the Heel? Answer:

3. Question:

I sharpened the bit. Why will it not cut?

• Maintain consistent inward light pressure during the half-turns of the Chuck. www.drilldoctor.com 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. www.drilldoctor.com

6. Question:

Cleaning Your Drill Doctor Why is the Chisel Edge on my drill bit flat? With the Drill Doctor unplugged, shake accumulated drill bit grinding dust from behind the Wheel Access 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. Answer: During the alignment process the Alignment Fingers may have been gripping the high points of the drill bit. Reinsert the drill bit in the Chuck making sure that the Alignment Fingers grip the narrowest section of the bit (the flutes) and the Leading Edge of the Flute is against the Alignment Finger. (See page 7-8.)

7. Question:

Why does the drill bit back up into the Chuck during the sharpening procedure? Answer: Make sure the bit is tight in the Chuck before sharpening. Your Chuck may be dirty. Clean the Chuck as described on page 17.

8. Question:

Can I change a 135° drill bit into a 118° drill bit? Answer: You can change the point angle of any drill bit from 135° to 118° by using normal sharpening procedures. 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 With the Drill Doctor unplugged, use your nail or the tip of your finger to pull the Wheel Access Cover forward. It will come completely off for easy access. To close, insert the Cover in the slots and snap it back into place.

www.drilldoctor.com Cleaning the Chuck Unscrew the Knob from the body and clean both threads with a soft brush or cotton swab. Re-assemble the Chuck and operate the Knob through its travel to ensure it turns freely. When the Chuck Jaws Knob is removed, be careful not to lose the small springs that separate the Chuck Jaws. Springs Determining if Replacing the Diamond Grinding Wheel Is Required You can double the life of the Diamond Sharpening Wheel by reversing it before you replace it. The Diamond 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 Sharpening Wheel may need to be changed if:

1. Sharpened drill bits burn or turn blue no matter how

fast or slow you rotate the Chuck.

2. When touching the Sharpening Wheel (with the

machine unplugged), the lower portion feels too smooth (nonabrasive).

3. When sharpening the drill bit, it takes too many halfturns to sharpen.
