Carmex Thread Turning Holder Standard is a precision tool designed for internal threading in metalworking. This left-hand configuration is built for reliability in deep bore applications and is ideal for machinists who demand consistent internal thread quality.

• Orientation: Left-hand internal threading configuration to match specific machine setups
• Overall length: 350 mm (OAL) to reach deep bores without repositioning parts
• Insert compatibility: Accepts 27IL inserts for established internal-threading performance
• Shank size: 50 for broad compatibility with standard tool-holding systems
• Holder type: U-Type holder engineered to secure U-Type inserts with a precise, stable fit
• Clamp design: Screw clamp threading bars for quick, secure setup and repeatable results
• Helix angle: 1.5° helix angle optimizes chip evacuation and reduces cutting forces

This combination delivers reliable, smooth internal threads with reduced tool load and longer life. The extended reach enables productive operations in hard-to-reach bores, while the screw-clamp setup and U-Type insert compatibility ensure quick, repeatable performance across multiple jobs. The 1.5° helix angle supports efficient chip flow for clean finishes, making this holder a dependable choice for internal threading tasks that require precision and consistency.
