Description

The Carmex MTSB Mini Type Through Coolant thread milling cutter is a precision solid carbide tool designed for metric threading in pre-drilled holes. It delivers clean, accurate threads (M6 x 1 and M8 x 1) with efficient cooling and chip evacuation, making it ideal for production environments that demand reliability and consistency.

  • Through Coolant Bore: High-pressure coolant is delivered directly through the tool into the pre-hole, cooling the cutting edge and flushing chips as the thread forms.
  • Solid Carbide Construction: Rugged, wear-resistant head that maintains accuracy and extends tool life in demanding threading applications.
  • Internal Cooling System: MTSB design features an internal bore to sustain stable temperatures at the cutting edge during the threading cycle.
  • Mini Type, Compact Design: Sized for tight spaces and challenging setups without compromising rigidity or performance.
  • Pre-Hole Threading Compatibility: Optimized for pre-drilled holes to produce precise metric threads with consistent pitch and depth.
  • Efficient Chip Evacuation: Coolant-assisted chip washing during the threading circle reduces clogging and helps achieve a smooth thread root finish.
  • Metric Thread Capability: Specifically engineered for M6 x 1 and M8 x 1 thread profiles with reliable dimensional accuracy.
  • MT7 Shank Interface: Designed to fit standard MT7 tool holders for secure, repeatable tool changes and rigidity.

Access to targeted cooling and superior chip management translates to improved thread quality, longer tool life, and reduced downtime. The through-coolant design helps keep temperatures under control, supports consistent surface finish on thread roots, and enables dependable performance in automotive, machinery, and precision fabrication applications. This Carmex cutter is the right choice when you need dependable metric threads from a compact, high-precision milling solution.
