Description

Carmex's MTSB Mini Thread Mills with through-coolant Bore are built for precise, reliable threading in through-holes across UNC, UNF, UNEF, and UNS standards. Designed for tight spaces and demanding applications, these solid carbide cutters deliver clean, accurate threads with enhanced heat management.

  • Through-coolant bore: Internal coolant is delivered under high pressure through the tool into the pre-hole, washing chips away during each threading pass and cooling the cutting edge for consistent performance.
  • Mini MTSB design: Compact geometry optimized for access in confined features while delivering solid carbide rigidity for stable threading.
  • Solid carbide construction: High hardness and wear resistance to maintain precise thread profiles over longer tool life.
  • MT7 shank: Compatible with standard MT7 tool holders for secure, vibration-free operation in milling centers.
  • UN thread compatibility: Specifically designed for UNC, UNF, UNEF, and UNS thread forms to cover a broad range of industry requirements.
  • No. 2 and No. 3 sizes: Available in two common thread diameters to match precision threading tasks.

This combination of internal cooling, through-coolant delivery, and carbide precision translates into practical benefits: cleaner chip evacuation during threading, reduced thermal impact on the cutting edge, improved thread quality with tight tolerances, and longer tool life in through-hole applications. The result is fewer reworks, smoother cycle times, and the ability to tackle challenging threads in automotive, aerospace, and general precision machining projects with confidence.
