Wolfram vanadium steel milling bits Selected wolfram vanadium steel. Purpose-made stable construction with head and shaft out of a single
cious metals, as well as plastics and plaster of Paris. All shafts Ø 2.35 or 3mm. Ideal for milling, routing, shaping, profiling and slotting. For clean and
HSS drill bits
HSS drill bits. Selected steel quality. Purpose-made stable construction with high concentricity. Shaft and bit are
manufactured from a one-piece blank. High hardness for optimum life expectancy and elasticity. For drilling metal, non-
ferrous metals, plastic, PC cards and wood. Work speeds: soft materials approx. 8,000rpm, hard materials approx. 3,000rpm. Ø shanks 2.35.
Tungsten carbide drills and milling bits
Tungsten carbide drills Made of wear-resistant tungsten carbide. For drilling
glass, semiprecious stones, porcelain, ceramics, marble and other hard stones. The
hard stones are subdivided according to the degree of hardness from 1 – 10. Tung-
sten carbide can be used up to hardness degree 6. Drilling hard stones with a hard-
ness degree of more than 6 calls for the use of diamond tools. Shaft Ø 3. With ideal
cutting angle of 6°.

MICROMOT steel collet set
Note:
MICROMOT steel collets are hardened and thus have a high, consistent
flexibility. They also maintain prolonged accuracy, even after
regular use (these collets should not be compared with unhardened,
four-slit collets of brass and aluminium). The triple slit collet is substan-
tially more difficult to manufacture than the four-slit type,
but offers a better load- bearing surface.
This is especially important for
cutters with small shaft diameters.
