Carmex Thread Turning Holder Standard - Internal - Left Hand - 300mm OAL - 22IL Insert - 40 Shank Size

The Carmex Thread Turning Holder for Internal Threading (Left Hand, 300 mm OAL) is engineered for precise internal threading in CNC and manual milling applications. It features a secure screw-clamp interface and is compatible with U-Type inserts for reliable, repeatable performance.

• Orientation: Left-Hand internal threading holder designed for specific threading directions.
• Overall length: 300 mm (OAL) to reach into deeper bores with stability.
• Shank size: 40
• Insert compatibility: Compatible with 22IL inserts and U-Type inserts for secure seating and versatility.
• Clamping method: Screw clamp provides a positive, repeatable grip and straightforward tool changes.
• Helix angle: 1.5° helix angle optimized for chip evacuation and reduced cutting forces.
• Application: Designed specifically for efficient internal threading operations in metalworking.

This holder delivers clean, accurate internal threads by combining a long reach, stable 40 shank, and precise insert seating. The 1.5° helix angle enhances chip flow and minimizes resistance during cutting, helping to extend insert life and maintain smooth tooling performance. The screw-clamp design makes setup quick and repeatable, reducing runout and improving overall production reliability. Ideal for shops that require dependable internal threading capability across a range of materials, from softer alloys to tougher steels, with consistent results and efficient workflows.
