Product Identity

This solid carbide roughing end mill measures 4x4x10x50MM with four flutes and an AlTiN coating. It targets CNC operators and machinists who need aggressive material removal on aluminium cast iron, steel, stainless steel and copper.

Build and Fit

The cutter uses raw solid tungsten steel hardened to HRC45 and a worked AlTiN coating for wear resistance. Right-angle drill geometry suits standard tool holders, while separate packaging protects each flute during storage and tool changes.

Upgrade Path

It replaces worn or lower-hardness roughers when cycle times must drop on the listed metals. The jump is worth it when existing tools cannot hold edge life on stainless or cast iron at comparable feeds.

Questions about this item

What materials can the HRC45 carbide end mill rough?

The cutter is rated for aluminium, cast iron, steel, stainless steel and copper.

What shank diameter does the 4 mm cutter need in a holder?

The shank measures 4 mm, so a 4 mm collet or chuck is required.

How deep should the tool be seated in the collet?

Clamp on the solid carbide shank behind the 10 mm flute length, not on the flutes themselves.
