The Carmex Thread Turning Holder with Carbide Shank is a purpose-built internal threading tool designed for machinists who demand rigidity, secure insert clamping, and reliable coolant-assisted cutting. Built for left-hand internal threads with through coolant, it supports a 16IL insert on a 25 mm shank and a 250 mm overall length for versatile reach.

• Tool type: Internal thread turning holder designed for screw-clamp inserts and precision threading.
• Through coolant: Integrated coolant bore provides efficient chip evacuation and edge cooling during internal threading.
• Left-hand configuration: Specifically configured for internal left-hand thread turning to match common machining setups.
• Length and shank: 250 mm overall length with a 25 mm shank size for extended reach and rigidity.
• Insert compatibility: Designed to accept a 16IL insert, aligning with Carmex threading insert standards.
• Screw clamp connection: Secure screw-clamp mechanism minimizes tool displacement during machining for consistent thread quality.
• Carbide shank: Carbide shank delivers stiffness and vibration resistance in demanding internal threading applications.

Designed to deliver dependable internal threads across a range of hole sizes, this holder combines a rigid carbide shank with a secure clamping system and efficient through-coolant cooling. The result is improved thread finish, greater tool life, and reduced setup downtime in both shallow and deep bores. Its left-hand orientation and generous 250 mm reach make it suitable for internal features where accessibility is a concern, while the 25 mm shank ensures robust rigidity under heavy cutting conditions. This tool is well suited for precision internal threading tasks in a variety of metalworking environments.
