3.135° degree tip angle - the best choice for higher cutting speed with less heat when drilling in tougher base materials
4.Longer-lasting drill bits in tougher applications - higher robustness and lifespan thanks to the cobalt content
5.Easier chp removal and optimised heat reduction - spiral flute for better lubricant distribution to the drill bit tip
HSS Twist drill bit Application
* Drilling into stainless steel, brass, copper and plastics
* Drilling into other tough metal (e.g. cast iron, titanium)
* Optimised performance reached when applying the right speed and cutting oil


135 Degree Split Point starts on contact with no
