Description

The Carmex MT7 Thread Mills Long Reach Through Coolant are specialized metric threading tools designed to tackle medium to large threads in deep workpieces. This two-tool set delivers reliable internal coolant threading with extended reach, making it ideal for bases, bottoms, and other hard-to-reach features.

  • Long reach through coolant design: Access deep internal threads and base-level features without repositioning the workpiece.
  • Through coolant capability: Efficient cooling and chip evacuation during high-speed thread milling for better surface finish and longer tool life.
  • MT7 interface: Specifically engineered to fit standard MT7 tool holders for stable, precise performance.
  • High rigidity and stability: Reduced vibration during cutting supports cleaner threads and higher process reliability.
  • Short cutting length for low cutting forces: Minimizes tool deflection and wear while sustaining productive feeds and speeds.
  • Thread lengths up to 3D: Versatile threading range in a single setup for more efficient operations.
  • Includes 2 tools: Provides starting and finishing capabilities across metric thread sizes without changing tooling mid-process.

In practice, these tools empower you to produce accurate, repeatable threads in challenging locations. The combination of long reach, internal coolant, and a compact cutting length translates to tighter tolerances, reduced cycle times, and improved surface quality. Perfect for jobs that demand deep, clean threads in bases or recessed features, the MT7 set helps you complete complex work with confidence and efficiency.
