Carmex Mini Thread Mills are engineered for precision threading in hardened metals, delivering reliable, high-quality threads in a compact form factor. Designed for shops that demand accuracy in tight pockets and small features, these mills excel where conventional tapping falls short.

• Material: Solid carbide for exceptional rigidity and wear resistance in hard materials up to 62 HRc.
• Size & Thread Form: 1/4" diameter with 20 TPI, compatible with UNC, UNF, UNEF, and UNS thread forms.
• Mini Geometry: Compact profile optimized for tight holes and constrained environments without sacrificing thread accuracy.
• Shank Interface: MT9 Morse taper shank for secure seating and consistent performance in standard milling heads.
• Finish & Precision: Geometrically optimized flute design to produce smooth cuts and a clean, precise thread profile.

This tool enables efficient thread milling directly in hardened steels and other tough alloys, reducing the need for tapping and enabling both internal and external thread creation with tight tolerances. Its carbide composition minimizes wear, helping maintain consistent thread quality across multiple passes, while the mini form factor supports repeatable results in space-limited setups. Ideal for mold making, aerospace components, and automotive fixtures where precision threads in hard materials are essential.
