Short series.
The cobalt Co content in the alloy increases drill life. Alloying with cobalt also increases the red hardness (the ability to withstand overheating without degrading properties).
Without additional hardening coating.
Right-cutting, sharpening 135 °, those. for hard materials.
Sanded.
Two cutting edges, two spirals.
The shank diameter corresponds to the drilling diameter.
The 135°angle sharpener defines the recommended application for drilling the following materials:
