A drill bit designed for difficult materials, greater heat resistance and longer tool life in every application.
In machining, the material changes everything.
There's no doubt: drilling hard steels, stainless steel or titanium demands a tool that goes far beyond conventional HSS. A drill bit that can't handle heat or cutting effort wears out fast, breaks sooner and cuts into productivity.
How to solve it?
The HSSCo 8% drill bit from Hepyc Cutting Tool Experts has been designed to work where other drill bits can't: greater heat resistance, better performance on difficult materials and longer tool life on the most demanding materials in the workshop.
Heat resistance for the hardest materials
The 8% cobalt content in the high-speed steel composition provides far superior heat resistance compared to standard HSS, maintaining cutting edge hardness even under intense cutting conditions. Its 135° Split Point tip guarantees precise self-centering from first contact, reducing entry effort and minimising the risk of breakage.
A drill bit built to work harder, last longer and cause fewer problems.
The 25–30° helix angle facilitates efficient chip evacuation, keeping drilling smooth and reducing heat build-up in the cutting zone.
The result:
-
Fewer interruptions
-
Less wear
-
A cleaner finish in every hole.
Application versatility
The HSSCo 8% drill bit is ready for an exceptional range of materials: steels, cast irons, non-ferrous metals, plastics, titanium alloys, superalloys and hard materials such as Hardox 500.
A single tool for multiple applications, both in series production and in maintenance and repair work.
What does a professional gain?
-
Greater heat resistance, without losing edge on the hardest materials.
-
135° Split Point tip: precise self-centering, less effort and reduced risk of breakage.
-
Efficient chip evacuation for smoother, clog-free drilling.
-
A single drill bit for multiple materials: more productivity, fewer problems.

Frequently asked questions
What materials can it work on?
Steels, cast irons, non-ferrous metals, plastics, titanium alloys, superalloys and hard materials such as Hardox 500.
Why does it handle heat better than a conventional HSS drill bit?
The incorporation of 8% cobalt in its composition significantly increases the thermal resistance of the cutting edge, keeping it active even in demanding cutting conditions.
What is the advantage of the 135° Split Point tip?
It allows precise self-centering from first contact, reducing penetration effort and the risk of breakage, with no need for a centre punch.
