OPERTATION
For drills from
320 mm
use the prism including the inner jaws. For drills from
2040 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 (see picture 2).
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 (1 , picture 1 ). The numbers on the jaws
shall not be visible. Softly tighten the fixation screws (picture 2) do not tighten too strong.

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 (picture 3). Drills from
Ø 335 mm
, cutting edge to graduation notch. Drills from
Ø 3540 mm
, cutting edge to
total length of the pin. Then align the cutting edge parallel to the slantwise graduation line
(picture 4).
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 (picture 2, Pos. 1 ). Move back pin (1 ) and fix the screw.
Broken drills, first pre-sharpen till they are flat.
