The Carmex MTB Through-Coolant Thread Mill is a precision solid carbide tool engineered for high-accuracy BSPT thread machining. Designed for professionals in hydraulic, pneumatic, and mechanical assemblies, it delivers clean, consistent threads with reduced downtime and extended tool life.

  • Through-Coolant Bore: coolant is delivered directly through the bore to the cutting zone, enhancing chip evacuation, reducing heat at the thread root, and improving bore finish.
  • Solid Carbide Construction: rigid, wear-resistant material for stable performance at higher speeds and feeds, delivering consistent thread quality over many cycles.
  • MT7 Morse Taper Shank: secure, vibration-resistant coupling to standard CNC spindles, ensuring reliable runout and repeatable results.
  • BSPT Thread Milling Capability: specifically engineered for BSPT threads with RC1/4 to RC3/8 x 19 sizing, optimized for efficient, accurate thread formation.
  • MTB Line Innovation: built on Carmex’s MTB lineage, combining advanced cooling through the bore with robust tool design for stronger longevity and dependable performance in demanding setups.

With through-coolant threading, this tool helps you eliminate chip build-up inside the hole, maintain steady cutting conditions, and achieve precise thread profiles faster. It’s ideal for production environments where BSPT fittings, pipe joints, and threaded manifolds demand reliable, repeatable results, long tool life, and reduced maintenance downtime. Whether you’re machining hydraulic blocks, pneumatic manifolds, or corrective repairs, this MTB thread mill offers a dependable balance of rigidity, efficiency, and longevity.
