The Carmex Fast MT solid carbide thread mill is built for high-speed internal threading, delivering precise G-type BSP/BSF threads with dependable coolant delivery for demanding machining environments.

  • Flute count (5–8): A higher flute count boosts cutting edges, enabling faster material removal and smoother thread finishes across a range of materials.
  • Internal coolant bore: Integrated coolant channel directs cooling fluid to the cutting zone and aids chip evacuation for cleaner threads and longer tool life.
  • 55° G-thread form: Optimized for G (55 Degree) BSP/BSF threading, ensuring accurate thread profiles and reliable mating with corresponding components.
  • Thread size and pitch: G1/8 x 28 threading specification tailored for common BSP/BSF applications with consistent engagement and fit.
  • MT8 shank: Standard MT8 shank for straightforward integration with compatible tool holders and automated machining setups.
  • Material: Solid carbide construction provides rigidity, wear resistance, and long-term performance in challenging metals and alloys.

Designed to shorten cycle times without compromising thread accuracy, this tool excels in precision threading tasks such as valve bodies, hydraulic fittings, and threaded adapters. The combination of a multi-flute geometry, efficient internal cooling, and a robust MT8 shank makes it a reliable choice for high-production environments where consistent thread quality and tool life matter. Use it for internal G1/8 BSP/BSF threads on hard metals and alloys, where sharp start, clean thread valleys, and reduced heat buildup are critical to success.
