Designed for CNC threading in bores, the Carmex Quick Change (CAT) Polygon Thread Turning Holder is an internal, right-hand tool that delivers fast, reliable thread cutting. Engineered for repeatable precision across multiple thread profiles, it helps shops boost throughput in automotive, aerospace, and general manufacturing environments.

• CAT polygon interface: Compatible with the CAT toolholder system to enable rapid, tool-to-tool changes in CNC machines.
• Internal thread turning holder: Specifically designed for internal threading operations, delivering accurate bore threads.
• Right-hand configuration: Optimized for standard right-hand threading applications in a variety of materials.
• 75 mm overall length (OAL): Provides reach into deep bores while maintaining rigidity and balance.
• 22IR insert compatibility: Uses 22IR geometry inserts for consistent thread profiles with a securely clamped carbide insert.
• C6 shank size: Matches standard C6 shank interface for secure seating in CAT holders.
• Quick Change system: Carmex Quick Change design reduces downtime with fast, repeatable tool changes.
• Rigid polygon design: Polygon geometry enhances rigidity and concentricity for precise thread cutting.

This holder is built for reliability across a broad range of threading tasks, from fine-pitch to mid-range threads. It minimizes setup time, supports high-volume production, and ensures consistent thread quality across runs. Ideal for use in automotive, aerospace, and manufacturing environments where precision and efficiency matter—and where quick tool changes can significantly boost overall productivity.
