Accupro 785006 ER32 Collet 0.531 Inches

Product Description

The ACCUPRO 785006 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accepts ER32 toolholding systems. This collet has a decimal inch size of 0.531 inches and a minimum collet capacity of 0.516 inches, giving it a clamping range suitable for holding round shank cutting tools, drills, and end mills within that span. It measures 1.75 inches in height and 1.5 inches in width and length, and weighs 0.35 pounds. Machinists and tool-and-die professionals rely on ER-series collets for their consistent runout performance and broad compatibility across standard spindle noses.

This collet is appropriate for use in production and job-shop environments where ER32 collet chucks are installed. It is suited for light to medium milling, drilling, reaming, and tapping operations on both ferrous and non-ferrous materials. The 0.531-inch size addresses tooling that falls within the upper portion of the ER32 clamping range, making it a common selection when working with larger-diameter shank tools in that series.

Installation Notes

ER32 collets are installed by a qualified machinist or toolroom technician. Before changing collets, the machine spindle must be fully stopped and the control placed in an estop or locked-out state per OSHA lockout/tagout requirements. The collet should be seated properly into the ER32 nut before threading onto the chuck body, and tightened with the appropriate ER collet wrench to the chuck manufacturer's specified procedure. Do not use impact tools to tighten or loosen ER collet nuts.
