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 tightened 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 the 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 tightens it.
5. Turn the chuck set a little to the anti-clockwise and taking it out ※ Make sure the cutting lip of drill is parallel with the slot of clam nut before grinding job started. If it is not parallel, adjust it again.

Scale Edge of drill touch the block Push forwarder to the end, then turn clockwise to the stopper Parallel

Attention: If the cutting lip is downward, must increase the scale of v adjustment shelf. If it is upward, please decrease the scale of the w 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 s Insert the drill gently into grinding shelf until reach the grinding wheel Grind the drill by moving left and right until the grinding sound disap 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

Point angle can be adjusted from 95° to 135° Grinding sample

D. Grind the lip relief angle

Put the chuck set into the point splitting shelf. The slot of clamping fit with the pin of the grinding shelf.
