Description

Solid carbide thread mill for internal 9/16 x 12 TPI UN threads. MTSH is from Carmex’s HARDCUT range, made for threading hardened material up to 62 HRc. It works well for die and mould work. The short profile keeps cutting forces low.

This is an internal-only thread mill, and Carmex doesn’t list it for external threads – that’s what the separate EMT range is for. MT9 is sub-micron carbide with a PVD triple coating, developed for hardened material. Carmex rates this tool for material up to 62 HRc. It’s a left-hand cutting tool, so program the spindle in reverse (M04).
