M35 High Speed Steel Bar

When cutting heat causes a tool edge to soften and wear quickly, M35 high speed steel bar offers a step beyond general-purpose M2. It contains about 5% cobalt, which helps the finished tool retain hardness at higher working temperatures.

M35 is often considered for drills, taps and cutters used on stainless steel and other demanding materials. Its value is strongest where improved tool life can reduce sharpening, replacement or machine stops. Cobalt content alone does not guarantee that improvement; tool geometry and cutting conditions still matter.

Dexter Steel can supply M35 bar stock with cutting and specified processing. For repeat tool production, blank size and supply condition help control machining work before hardening and final grinding.

More Details

M35 contains about 5% cobalt, which helps the cutting edge stay hard as heat builds. It is often considered for drills, taps and cutters working on stainless steel and other demanding materials.

If M2 tools wear quickly under those conditions, M35 may extend the time between replacements. That can mean fewer machine stops and less time changing tools.

At Dexter Steel, we look at what you cut and why the current tool fails. If poor chip removal or an unstable setup causes breakage, changing the steel alone may not solve the problem.

Make the Upgrade Worth Its Cost

M35 costs more than M2. The useful comparison is how many acceptable parts each tool produces before sharpening or replacement.

For repeat jobs, include the time spent changing tools. A modest improvement in tool life can matter when every change interrupts a busy machine.

We can quote M35 cut blanks against your drawing. Suitable dimensions reduce machining and scrap while leaving enough material for hardening and final grinding. The required supply condition should also be clear on the order.
