• Industrial-Grade Carburized Material - Tapping Holder undergoes carburizing heat treatment and grinding for exceptional durability. This 20CrMnTi construction delivers high thermal strength and oxygen resilience, ensuring extended service in prolonged CNC machining processes.
• Hardened Thread Accuracy - Collet clamp features quenched and hardened threads for improved service life and accuracy. The compact design maintains consistent clamping force, reducing tap slippage during M2 to M30 threading applications.
• Internal Grinding Finish - Tool holder's internal hole receives grinding treatment for high-elaboration machine tool processing. This accurate engineering provides longer service life than standard holders while maintaining concentricity under 2000 RPM use.
• Telescopic Floating Function - Tension compression mechanism effectively slows CCW tap force, increasing tap lifespan by over 85%. This floating action prevents breakage from fast feed/retraction sequences while improving cutting efficiency in milling machines.
• Pressure-Controlled Protection - ERG32 adapter chuck delivers better elasticity and lower abrasion during use. The pressure-controlled system prevents tensile deformation and tap breakage, offering consistent performance for CNC machining centers.
