Carmex Mini Type Thread Mills are solid carbide tools designed for precision threading in hardened materials up to 62 HRc. Built for job shops and manufacturers that demand reliable performance, these MJ-series mills deliver consistent threads and exceptional surface finish.

• Mini thread milling design: Compact geometry optimized for small-diameter threads and tight work envelopes.
• Material: Solid carbide for stiffness, wear resistance, and long tool life in hard metals.
• Hardness capability: Specifically engineered to machine hardened materials up to 62 HRc.
• Size/Series: MJ series (MJ 14–MJ 20 x 2) with MT6 shank, ideal for precision threading applications.
• Shank: MT6 shank provides broad compatibility with common tool holders and CNC machines.
• Finish: Designed to produce an excellent surface finish on threaded features, minimizing finishing operations.
• Performance: High-performance threading solution that enables smoother cuts and predictable results on tough materials.

These features translate into real-world benefits: you can thread hardened steels and alloys with confidence, reach tight pockets and complex geometries, and rely on a durable carbide tool to maintain thread quality over many cycles. The compact MJ mini thread mills are a practical, dependable choice for precision fastening applications in aerospace, automotive, mold making, and general precision manufacturing.
