HSS-Co Twist Drill

The kwb HSS-Co twist drill bit is designed for precise drilling in demanding materials such as alloyed and unalloyed steel, stainless steel (V2A/V4A), grey cast iron, cast steel, bronze and plastics. The drill has a 5% cobalt alloy and is manufactured according to DIN 338. The 135° point angle with split point according to DIN 1412 C ensures self-centring drilling and prevents slipping. The right-hand cutting type N drill has a parallel shank that allows universal compatibility with drilling machines.
