Operation
For drills from 3-20 mm use the prism including the inner jaws. For drills from 20 – 40 mm
remove the inner jaws.
Removing of the inner jaws: Loosen the 4 pcs socket head cap screws with a suitable
key SW 2,5 mm
Mounting of the inner jaws:
Place the inner jaws inside the prism in the way that the graduation marks are in line
with the outer marks (Pic. 12) The numers on the jaws shall not be visible.
Softly tighten the fixation screws (Pic 13). Do not tighten too strong.
Clamping and alignment of right hand helix drills
Loosen clamping screw 2 and pull out the pin 1 to the stop dog and fix again
Depending on the diameter, let the drill project outside the prism (Pic. 9)
Drills from 3 – 35 mm cutting edge to graduation notch.
Drills from 35 – 40 mm cutting edge to total lengh of the pin.
Then align the cutting edge parallel to the slantwise graduation line. (Pic. 10).
For getting a parallel clamping of small drills, we propose to clamp a second drill of same
diameter on the back of the prism.
For drills with bigger diameter also use the prism elongation for the cylindrical part (Pic.13
item 1) Move back pin 1 and fix with the screw.
Brocken drills, first pre-sharpen till they are flat.

11
Grinding of right hand spiral drills
Adjust prism rest to 118°and support to scale value 0 (Pic 21) For the clearance angle
adjustment, open fixation screw and adjust with the eccentric locking screw to the value
listed below. (Pic 11). The smaller the scale number, the smaller the clearance angle. Take
off the star knob screw. Now start the motor and swivel the prism with drill by carefully
moving forward the slide in direction to the grinding wheel. Note the number on the scale and
move back. Open the small lever and turn the prism for 180 °. Finally check if the basic
alignment, saying that the cutting edge, is still parallel to the graduation line
Web thinning of helix drills
For additional web-thinning, do not remove the drill out of prism, Adjust clearance angle (pic
15) to 0 and lock the prism support with the star knob screw in hole C. Move the grinding
wheel with motor to the right. Open the clamping lever on the prism rest and turn to line “A”
(Pic 14) Now go forward and sharpen approx. 1/10 of drill diameter using the left side of the
grinding wheel behind the cutting edge inside the drill. For correct positioning, you must turn
prism- and motor feed. The width of the cross cutting edge should be approx. 1 mm for a drill
of dia 10 mm. Note the both numbers of prism and motor feed, turn the prism for 180 ° and
repeat the procedure.
