Extremely strong and with perfect concentricity due to drill crown and shank of one piece (hardened). Narrow carbide cutting edges with positive rake and large clearance angle provide good cutting performance at low cutting pressure. Exchangeable centre drill, shank with 3 clamping faces. Cutting width 1.9 mm for all sizes. ⌀ tolerance: + 0.15 / − 0.05 mm. Dimension L: all sizes = 11.8 mm.
Application:
For use on stationary machines. Highly suitable for sheets of plastic (GRP and CRP). Only for flat material up to 5 mm thickness.
