M35/DIN 3243 / AISI M35/
M35 is a cobalt-bearing high speed steel designed for higher hot hardness and superior wear resistance. The addition of cobalt significantly improves red hardness while retaining the toughness necessary for reliable tool life in difficult-to-machine materials like stainless steels and high-alloy steels. Its fine, uniform structure supports precision grinding and stable edge retention, making it the preferred choice for high-speed production tooling where downtime must be minimized.
Key Features
- Enhanced red hardness (Cobalt)
- Excellent wear resistance at heat
- Good toughness for interrupted cuts
- Stable edge in hard materials
- Reliable heat treatment response
Typical Applications
- Heavy-duty drills and taps
- Broaches and gear cutting tools
- End mills and milling cutters
- Stainless steel machining tools
- High-speed production tooling
