Description
Solid carbide thread mill for internal No. 6 x 32 TPI UNJ threads. This is the Mini Mill-Thread in MJ/UNJ form, the controlled-root-radius threads used on aerospace fasteners. The short profile keeps cutting forces low on small diameters.
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. MT8 is sub-micron carbide with a PVD triple coating that stands up to high heat and cuts smoothly in all materials. Carmex rates this tool for material up to 52 HRc.
