The Carmex Screw Clamp Thread Turning External Holder (Right Hand, 170 mm OAL) is a precision solution for external threading tasks, built to deliver stable, repeatable results in demanding shop environments. Designed to hold 27ER inserts with a robust screw-clamp and a 32x32 shank, it prioritizes rigidity and accuracy across every pass.

• Right-Hand external thread turning holder: specifically configured for right‑hand threading operations to match common shop setups.
• 170 mm overall length (OAL): extended reach for reach-sensitive threading applications while maintaining rigidity.
• 27ER insert compatibility: optimized for the 27ER insert style, enabling precise external threading performance.
• 32 x 32 shank size: standardized shank footprint for secure mounting on compatible tool holders and machines.
• U-Type holder design: accommodates U-Type inserts for specialized thread forms and accurate alignment.
• Insert compatibility: supports ER and EL insert families for versatile threading options.
• 1.5° helix angle: engineered to improve chip evacuation and cutting efficiency during threading passes.
• Screw clamp mechanism: robust clamping delivers exceptional rigidity and minimizes tool deflection during heavy cutting.
• Robust construction: built to withstand the rigors of continuous external threading operations with reliable performance.

This holder provides a stable, precise platform for external thread turning, reducing runout and chatter while enabling quick insert changes through a secure screw-clamp system. Its combination of long reach, specific right-hand orientation, and compatibility with ER/EL insert families makes it a practical choice for shops that demand consistent thread quality, reduced cycle times, and durable tooling that stands up to daily use.
