Carmex Thread Mills Solid Carbide with Through Coolant is designed for precise internal threading in metric holes, delivering dependable performance for precision shops and high-volume manufacturing. With a through-bore coolant design and MT7 shank, it supports clean chip evacuation and consistent hole quality in challenging depths.

• Through-Coolant Bore: Coolant is delivered through the tool bore to the cutting zone, enhancing chip removal and reducing friction inside deep or tight holes.
• Solid Carbide Construction: Hard-wearing carbide body for high rigidity, wear resistance, and stable threading under demanding conditions.
• Metric Size: M20 x 1.5 thread profile, suitable for common metric fasteners and standard machining setups.
• MT7 Shank Interface: Robust MT7 connection for precise alignment and rigidity in CNC milling centers.
• Internal Thread Milling: Optimized geometry tailored for accurate, high-quality internal threads in a single or multi-pass process.
• MTB Line Innovation: Builds on proven MT tooling with enhanced cooling-by-design to extend tool life and improve reliability in production environments.

The through-coolant capability helps minimize chip buildup, which can compromise thread accuracy and hole finish. By cooling the cutting edges from within the bore, this tool sustains sharper threads, reduces wear, and lowers overall tooling costs over time. Ideal for automotive, aerospace, and general precision applications that demand repeatable internal threads, long tool life, and efficient chip management. Operators benefit from fewer tool changes, steadier hole quality, and better surface finish in challenging materials and deeper holes.
