RUKO punta corta DIN 1897 HSS-Co5 Ø6,5 mm

Stub drill bit for precise, short-hole drilling in tough materials. The RUKO SPB-DIN1897-HSSCo-Ø6,5mm combines a rigid stub length with HSS-Co5 cobalt steel for high wear resistance and heat tolerance, making it ideal for stainless steel and other hard metals.

Advantages

Fully ground from HSS-Co5 (5% cobalt) for superior hardness and durability. The 135° split point reduces walking and requires less pilot drilling. Bright finish aids chip flow and reduces friction.
