Description

The Carmex Thread Turning Holder with carbide shank is a precision internal threading tool built for machinists who demand rigidity, consistent thread quality, and efficient coolant management.

  • Orientation: Right-hand internal threading holder designed for reliable internal thread production.
  • Material: Carbide shank delivers high stiffness and minimized tool deflection under load.
  • Through coolant: Integrated coolant bore ensures effective chip evacuation and cooling during cutting.
  • Retention: Screw clamp mechanism provides a secure connection between the holder and the insert to minimize tool displacement.
  • Length: 125 mm overall length (OAL) for versatile reach in various setups.
  • Insert compatibility: Designed for 08IR inserts for robust threading performance.
  • Shank size: 8 mm shank suitable for standard threading applications and compatible tooling setups.

This threading holder is ideal for machinists tackling internal threads across a range of bore diameters. The carbide shank delivers stability in demanding materials, while the through-coolant design helps maintain cutting efficiency and prolong tool life. The screw clamp connection minimizes run-out and tool movement, enabling cleaner finishes and consistent pitch accuracy. With its compact 125 mm length and 8 mm shank, it integrates smoothly into tight machining envelopes without sacrificing rigidity or control.
