ER collets with radial compensation

Correct center-line misalignments and protect delicate taps during CNC lathe and multi-axis tapping operations with industrial-grade ER Collets with Radial Compensation (floating tapping collets). Designed to mount into standard ER collet chucks, these specialized collets feature an internal radial float mechanism combined with a positive-drive square socket. By allowing controlled radial movement (parallel float), they compensate for position errors between the pre-drilled hole axis and the machine spindle, ensuring the tap follows the hole true-to-center to produce clean, non-bell-mouthed threads and prevent tool breakage.
