The Carmex Thread Turning Holder Standard – Internal (Left Hand) is a precision tool holder built for reliable internal threading in deep bores and precision components. With a 250 mm overall length and a 32 shank size, it’s designed for rigidity and consistent performance, and it accommodates 22UIL inserts for versatile threading options.

• Left-hand internal threading holder: Optimized for left-handed threading operations, delivering predictable cuts and consistent thread quality.
• Internal threading compatibility: Intended for precise internal thread creation with secure insert seating.
• 250 mm OAL: Long reach to access deep bore threads without sacrificing rigidity or control.
• 32 shank size: Sized to fit standard machine tooling setups for dependable mounting and alignment.
• 22UIL insert compatibility: Supports 22UIL inserts for a range of thread profiles and materials.
• U-Type insert compatibility: Designed to pair with U-Type inserts for a secure, precise fit and easy interchangeability.
• 1.5° helix angle: Helix angle improves chip evacuation and reduces cutting forces for smoother threading operations.
• Screw clamp design: Secure screw-clamp mechanism ensures repeatable toolholding and reliable insert changes.

This holder excels in applications such as producing internal threads in bushings, sleeves, hydraulic fittings, and other bore-focused components. The left-hand configuration is ideal for workflows where threading direction matters, while the 1.5° helix angle and robust seating reduce chatter and extend insert life. For best results, pair with compatible U-Type inserts and use the screw-clamp feature to maintain consistent performance across multiple jobs.
