Accupro 785003 ER32 Collet 0.349 Inch

Product Description

The ACCUPRO 785003 is an ER32 series collet designed for precision workholding in CNC machining and milling applications. It accepts round stock and tooling up to 0.349 inches, with a minimum collet capacity of 0.313 inches, providing a defined clamping range suitable for a variety of end mills, drills, and round-shank cutting tools. The collet measures 1.75 inches in height and 1.5 inches in diameter, fitting standard ER32 collet chucks. Weighing 0.35 pounds, it is a compact, single-piece tool-holding component installed by machinists and CNC setup technicians in production and job-shop environments.

ER32 collets are widely used in vertical machining centers, horizontal mills, and manual knee mills equipped with ER32-compatible chucks or tool holders. This collet is appropriate for general-purpose metal cutting, woodworking, and composite machining where consistent runout control and secure tool grip are required. It suits both production-run and prototype machining scenarios where repeatable tool holding is critical to dimensional accuracy.
