Designed for high-precision internal threading, Palbit Threaded Coupling Holders deliver rigidity and secure insert retention when paired with RD12T3 inserts. With a 30 mm cutter diameter, this holder supports accurate thread profiles in demanding CNC threading operations.

• Compatibility: Specifically designed for RD12T3 inserts to ensure a reliable, drop-in fit at operation start.
• Rigidity and retention: Robust clamping and coupling geometry minimize insert movement for consistent thread form and longer tool life.
• Cutter diameter: 30 mm cutting diameter tailored for mid-range internal threading tasks.
• Threaded coupling design: Precision-engaged threaded interface distributes load evenly for accurate thread profiles.
• Chip evacuation: Optimized geometry promotes efficient chip removal, reducing heat and downtime.
• Durable construction: Machined from strong materials with a precise finish to withstand tough CNC environments.

This coupling holder translates machine power into repeatable, high-quality internal threads. The secure insert retention and rigid design minimize vibration and deflection, delivering clean thread starts, improved surface finish, and longer tool life. Efficient chip evacuation means less downtime for chip clearing, enabling higher productivity in precision machining environments.
