Description
Solid carbide thread mill for internal No. 8 x 36 TPI UN threads. DMT is a 3-in-1 tool that drills the hole, cuts the thread and chamfers the edge in one circular-interpolation cycle, so there’s no separate drill and no tool change. It has internal coolant and works in blind or through holes.
This is an internal-only thread mill, and Carmex doesn’t list it for external threads. MT7 is Carmex’s general-purpose grade: sub-micron carbide with a TiAlN multi-layer coating, meant to run at medium to high cutting speeds across all materials. It’s a left-hand cutting tool, so program the spindle in reverse (M04).
