Carmex MTB Thread Mills are precision solid-carbide tools designed for metric threading on CNC mills. Built for machinists who demand reliable M10 x 1 threads with consistent quality and longer tool life, these through-coolant mills deliver efficient, repeatable results.

• Through-Coolant Bore: Coolant is delivered directly through the bore to flush chips from the hole and cool the cutting edges for cleaner, more accurate threads.
• Solid Carbide Construction: Rigidity and wear resistance deliver durable performance under demanding cutting conditions.
• Metric Thread Specification: Engineered specifically for M10 x 1 threads, ensuring precise pitch and thread form.
• MT7 Shank: Designed to fit MT7 holders for stiff, stable milling and reduced runout in high-precision work.
• Chip Control & Longevity: The coolant-through design minimizes chip build-up and heat, extending tool life for cost-effective production runs.

The MTB line addresses common threading challenges by combining efficient chip evacuation with active cooling, enabling deeper milling passes, tighter tolerances, and cleaner thread surfaces. Ideal for metal parts in automotive, aerospace, and general precision manufacturing where secure fasteners and repeatable threads matter, this tool helps reduce downtime and tool replacement while delivering dependable, consistent results.
