Product attributes
Clamping element
more +Plain straight shank according to DIN 6535 HA.
Type N
more +Normal profile of flute, normal core, point angle 118°. Drills made of HSS Co mildly strenghtened core, point angle 130°.
Point angle 135°
Right helix
Solid carbide
more +Carbide materials are characterised by high compressive strength, high hardness and therefore high wear resistance, but also limited flexural strength and toughness.
Company norm
Point shape - form N
more +Conical lip relief, DIN 1412 form N.
