The Carmex Thread Turning Holder Standard – Internal, Right Hand is a precision tool designed for internal threading tasks. It’s built to secure 27UIR U-Type inserts and deliver consistent, accurate threads in a right-hand orientation.

• Right-Hand internal thread turning holder: Optimized for clockwise internal threading in standard machining setups.
• 250 mm overall length (OAL): Extended reach to access deeper holes without compromising rigidity.
• Ø32 mm shank size: Robust shank for stable engagement with toolholders and reduced deflection.
• 27UIR U-Type insert compatible: Specifically designed to accept the 27UIR U-Type inserts for precise geometry and repeatable results.
• 1.5° helix angle: Gentle helix promotes efficient chip evacuation and lowers cutting forces during threading.
• Screw clamp threading bars: Secure, quick-clamp mechanism that minimizes runout and holds the insert firmly in place.
• Left-Hand variant available: Offered in a left-hand orientation to cover additional internal threading needs.

With the Carmex Thread Turning Holder, you’ll achieve clean, accurate internal threads even in challenging components. The long reach enhances accessibility to deep features, while the rigid Ø32 mm shank maintains stability for better surface finish. The 1.5° helix angle improves chip flow and reduces heat buildup, and the screw clamp system ensures the insert stays fixed under cutting forces. Designed to pair with 27UIR U-Type inserts, this holder supports repeatable results across multiple workpieces, making it a reliable choice for automotive housings, hydraulic components, molds, and other precision applications.
