HSS Drill Bit Description

HSS drill bit Features

1. Precision-ground HSS-Co drill bits with 5% cobalt content
 

2.Specially designed tip with split point - for precise self-centring, fast start and less walking on surface

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 holes into high alloyed and unalloyed steel and heat-treated steel ≤1100 N/mm²
* 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

 

     Special Design: 
135 Degree Split Point starts on contact with no
walking or skating and no center punch is required

Applied material:

Light-gauge metal, high-carbon steel, aluminum and ally steel, cast iron, stainless steel,cast iron, wood, plastic
