The Carmex Thread Mill Carbide Mini Type delivers precise UN threads in one reliable tool. Machinists use it for internal and external threading in deep holes where taps often fail.

• Carbide Grade: MT7 sub-micron carbide with titanium aluminum nitride multi-layer coating for heat resistance and extended life
• Thread Size: No. 12 x 28, compatible with UNC, UNF, UNEF, and UNS thread forms
• Cutting Speeds: Supports medium to high speeds on materials up to 45 HRc without excessive wear
• Flute Design: Spiral flutes with 3 to 5 cutting edges and internal coolant channels for efficient chip removal
• Profile Length: Short cutting profile reduces forces and prevents tool breakage during deep-hole work

This thread mill replaces multiple taps and dies by handling a wide range of pitches on both external and internal surfaces. The design cuts machining time while producing clean threads in hardened steels, aluminum, and stainless without the risk of broken taps in blind or deep holes.
