Carmex MJ Thread Mills are compact, solid carbide tools engineered to deliver reliable threading in hardened materials. Designed for machinists who demand precision and long tool life, these mini-type mills excel at creating clean, accurate threads in tough metals up to 62 HRc.

• Construction: Solid carbide for maximum rigidity, wear resistance, and long service life in hard workpieces.
• Thread milling design: Optimized geometry for precise internal thread creation with a smooth finish and minimal chatter.
• Material suitability: Specifically engineered to machine hardened materials up to 62 HRc with consistent results.
• Sizes and shank: MJ 8 and MJ 10 with a 1.25 mm thread pitch, MT6 shank for compatible mounting in common milling centers.
• Cutting performance: Efficient chip evacuation and stable cutting that helps achieve better surface finish and reliable thread profiles.

These thread mills deliver dependable performance in demanding applications, reducing rework and extending tool life. The MT6 shank and precise 1.25 mm pitch make them a practical choice for standard metric fasteners and threaded features in hardened steels, molds, and precision components. For best results, follow Carmex recommendations for feeds, speeds, and coolant to optimize cut quality and tool longevity.
