Frequently Asked Questions - MR-13B Vevor

What types of drill bits can I sharpen with the Vevor MR-13B?

The device can sharpen HSS twist drill bits with a diameter of 2 mm to 13 mm (15 mm max).

How do I install the drill bit into the chuck?

Select the clamping collet suitable for the drill bit diameter. Insert the collet at 45° into the ER20 chuck and tighten the nut slightly. Insert the drill bit leaving about 35 mm of shank protruding from the chuck, but do not fully tighten before alignment.

How do I properly align the drill bit before grinding?

Use the band adjustment shelf: set the scale ring to the drill bit diameter, insert the chuck, turn fully clockwise, then insert the drill bit until the cutting lip is parallel to the clamping slot. Adjust the scale if necessary.

What point angles can I achieve?

The point angle is adjustable from 95° to 135° via the point angle grinding shelf.

How do I sharpen the lip relief angle?

Place the chuck in the lip relief shelf. The slot of the clamping nut must fit the pin. Gently insert the drill bit up to the grinding wheel and move it laterally until the grinding noise stops. Turn the chuck over for the other side.

What safety precautions should I take?

Always wear ANSI safety glasses, hearing protection, and gloves. Do not wear loose clothing. Keep children away. Unplug the device before any maintenance. Do not use near flammable liquids.

How do I replace the diamond grinding wheel?

Unplug the device. Open the wheel cover with a 4 mm hex key. Hold the grinding wheel with one hand and loosen the screw counterclockwise. Replace the new wheel, tighten the screw, and close the cover.

Can I use this sharpener for wood or metal drill bits?

Yes, it is suitable for standard HSS drill bits used for wood and metals. Do not use for carbide drill bits without recommendation.

How do I clean the device after use?

Use a compressed air blower to clean grinding residues, especially the holes. Wipe with a dry cloth. Do not use alcohol, gasoline, or abrasive materials.

OPERATIONS

A. Setup the drill bit to the ER collet chuck.

*Please follow step 1, 2 to set up the drill bit to the chuck (without tightening).

1. Determine diameter of your drill bit, and then select the proper collet chuck.
2. Insert collet into collet chuck by 45° angle, and tighten nut slightly.
3. Insert drill bit into collet chuck and nuts out 35mm or so from the chuck, but do not tighten the drill too tight.

※ Do not fully fasten the clamping nut with collet chuck, keep the drill able to be adjusted.

B. Align drill bit

1. Reset the scale ring: turn the ring all the way clockwise, and then anti-clockwise to the number same as the drill's size.
2. Insert the chuck set into the web adjustment shelf. Then connect Turn it clockwise to the end.
3. Plug the drill to the end and turn it clockwise to the end.
4. Turn the chuck set clockwise to the end and tighten it.
5. Turn the chuck set a little to the anti-clockwise and take it out ※ Make sure the cutting lip of drill is parallel with the slot of clamping nut before grinding job started. If it is not parallel, adjust it again.

Attention: If the cutting lip is downward, must increase the scale of the adjustment shelf. If it is upward, please decrease the scale of the weight adjustment shelf.

When the flute length of a drill becomes shorter, the web thickness would become thicker. So, for the same diameter of drills, the shorter length of a drill, the higher scale of web adjustment shelf need to be increased.

C. Grind the point angle

Turn the power switch on and wait until the motor rotation is stable (10 seconds), put the chuck set into the point angle grinding shelf. The slot of clamping nut must fit with the two pins of the grinding shelf. Insert the drill gently into grinding shelf until reach the grinding wheel. Grind the drill by moving left and right until the grinding sound disappears. And then turn to the other side, do the same to grind the drill.

* The grinding size of drill is 2mm-13mm(15mm) * The point angle of drill is from 95° to 135°. * While grinding, don't hold the stem of drill, it will affect the accuracy.

D. Grind the lip relief angle

Put the chuck set into the point splitting shelf. The slot of clamping fits with the pin of the grinding shelf. Insert the drill gently into grinding until it reaches the grinding wheel. Grind the drill by moving left and right until the grinding sound disappears. Turn back to the center of the pin and then turn to the other side, do the same to grind the drill.

Grinding sample

Notice: The lip relief angle is adjustable by taking out the pin to the other holes. Our standard is the smallest (in the position of No.4&5) for grinding the lip relief face. If you need a big size for the relief face, put the pin near to the grinding wheel, then grind. There are four positions such as: NO.4&5, No.3&4, No.3, No.1&2.
