ERG Tapping Collet Chuck for CNC, 18x14.5 Thread M22

【Automatic Retraction】The built-in automatic retraction mechanism prevents tool jamming during automated cycles, keeping the collet free and snag-free on the tool holder.
【Precision Tapping】The precision M22 tapping provides 0.015 mm concentricity for stable, high-speed threading, ensuring accurate hole alignment on CNC milling machines and engraving lathes.
【Shock-Resistant Body】The collet body, made of HSS steel, absorbs lateral stress to protect the collet from sudden breakage under heavy loads.
【ERG Compatibility】Designed specifically for 18x14.5 mm diameter ERG collets with M22 threading, it fits standard CNC milling and boring tool holders.
【Multi-Process Versatility】Suitable for precision repetitive machining in tapping, grinding, milling, boring and drilling on industrial engraving machines.
