Description

Experience precision threading with Carmex MTSB Mini Type through-coolant thread milling cutters. Built for metric threads M16 and M17x2, these compact, solid carbide tools excel in tight pockets and demanding materials.

  • Through-coolant bore: Delivers high-pressure coolant directly through the tool to the pre-hole and cutting zone, enhancing cooling and chip evacuation during the threading circle.
  • Internal coolant delivery: Coolant is directed to the critical cutting edge, reducing heat buildup and improving process stability.
  • Solid carbide construction: Offers stiffness and wear resistance for consistent thread quality over long production runs.
  • Mini Type form factor: Compact shank and body design for threading in restricted spaces without sacrificing rigidity.
  • Metric thread compatibility: Precisely engineered for M16 and M17x2 threads, enabling accurate and repeatable results.
  • MT7 shank: Standard MT7 interface ensures secure seating and reliable performance on compatible machines.
  • Thread milling optimization: Geometry and flute design tuned for efficient material removal and superior surface finish in threading operations.

The through-coolant design washes away chips as the cutting circle advances, while the coolant continuously cools the cutting edge. This combination improves thread quality, extends tool life, and reduces downtime due to unplanned tool changes. The slim Mini Type form fits into tight workholding and deep cavities, making it ideal for high-precision metric threading in sectors like automotive, aerospace, and medical device manufacturing where M16 and M17x2 threads are required.
