Engineered for precision BSPT threading through holes, the Carmex MTZ Through-Coolant Thread Mill delivers coolant directly through the flute channels to the cutting edge for cooler, smoother, and more consistent cuts. Built around a robust MT7 shank, this carbide tool pairs durability with broad machine compatibility, making it a reliable choice for tight-tolerance BSPT threads.

• Through-Coolant Flute Design: Coolant is directed through the tool’s flutes to the cutting edge, enhancing heat control and helping chips evacuate efficiently during thread milling through holes.
• Carbide Construction: Solid carbide body provides excellent wear resistance and sustained precision in demanding materials and prolonged production runs.
• BSPT Thread Form: Precisely ground for BSPT threads (RC1/8 x 28), ensuring accurate thread profiles and reliable engagement.
• RC1/8 x 28 Size: Specific size and pitch configuration optimized for through-hole BSPT applications.
• MT7 Shank: Morse Taper MT7 shank delivers rigid, stable mounting on compatible CNC spindles for repeatable results.
• Through-Hole Threading Focus: Geometric design tailored for threading through holes with direct chip removal, reducing downtime and cleanup.
• Small-footprint Versatility: Designed to perform well on machines without external coolant systems, expanding where and how you can produce BSPT threads.

This thread mill is ideal for shops needing precise BSPT through-hole threading with reliable coolant delivery, long tool life, and compatibility with a variety of CNC setups. By combining through-coolant technology, carbide durability, and a compact MT7 shank, it supports clean thread engagement, improved surface finish, and consistent production quality across challenging materials.
