Engineered for precision external thread turning, the Carmex Right-Hand Screw Clamp External Holder delivers stable, repeatable thread forms for machinists and shops. With a 200 mm overall length and a 40x40 mm shank, it provides a rigid, reliable platform for mid- to long-thread applications.

• Right-Hand external thread turning: optimized for right-handed threading operations with a secure screw-clamp grip for rigidity.
• 200 mm Overall Length (OAL): provides ample reach to machine longer, deeper threads while maintaining stability.
• 40 x 40 mm Shank: compact, square shank designed for compatibility with standard tool posts and straightforward alignment.
• 22ER Insert Compatibility: accepts 22ER inserts to ensure precise, consistent thread engagement and finish.
• ER/EL Insert Compatibility: supports ER and EL insert types for flexible tooling configurations according to material and thread requirements.
• U-Type Design: built to accommodate U-Type inserts for optimized grip and accuracy in external threading.
• 1.5° Helix Angle: a shallow helix angle to aid chip evacuation and improve cutting efficiency in turning operations.
• Robust Construction & Clamping: durable body and reliable clamping mechanism to minimize runout and vibration during heavy cuts.

The result is cleaner, more accurate external threads with improved surface finish and longer tool life. The secure screw-clamp reduces tool movement under load, while the helix angle promotes efficient chip flow and reduces built-up edge. The holder's reach and 40x40 shank fit typical CNC lathes and manual machines, making it a versatile choice for production runs or precision work across a range of materials. By choosing Carmex, you get dependable performance and predictable results batch after batch.
