Operation Procedure
Bits Of The Assembled Group Fixture :
- Make sure the material of the drill and choose a suitable grinding wheel.
- Standard iis CBN grinding wheel.* CBN wheel is suitable for HSS drill, SD wheel is suitable for carbide drill.
- Set left scale annulus to be “0” position. Turn the scale clockwise to the end, then contra rotate to adjust to the “0” position.
- Choose a suitable collet for the collet holder. (Insert the collet into holder in the 45 degree)

Turn on the power of the grinder, then insert the collet holder with a drill and push to the grinding wheel slowly. Next, move left and right repeatedly to sharpen the drill until the grinding sound disappeared. Take out the chuck, turn 180degree and repeat the same process. * Don’t hold the drill when you grind, or it will influence the grinding.
*Point angle can be adjustable from 90 degree to 180
Grind The Front Cutting Up :
