CMM ER11 Collet Chuck (Inch)

Inspection Arsenal® CMM ER Collet Chucks hold round bar stock, pins, shafts, and cylindrical components with precision concentricity during coordinate measuring machine (CMM) inspection. The ER collet interface provides low total indicator runout (TIR), ensuring that measurement results reflect actual part geometry — not fixture-induced error.

Accepts standard ER collets for a wide range of bore diameters. Mounts directly to Loc-N-Load™ fixture plates for integration into a modular CMM workholding system.

Ideal for quality labs inspecting turned parts, gauge pins, and cylindrical features where concentricity and runout are critical measurements. Made in USA — Boylston, MA.
