Accupro 785016 ER32 Collet 0.438 Inches

Product Description

The ACCUPRO 785016 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other spindle-driven equipment that accepts ER32 toolholding systems. This collet holds workpieces or cutting tools with a maximum capacity of 0.438 inches and a minimum collet capacity of 0.422 inches, providing a secure, concentric grip across that clamping range. Measuring 1.75 inches in height with a 1.5-inch width and 1.5-inch length, it is compact and fits standard ER32 collet chucks. At 0.35 pounds, it is lightweight and easy to handle during tool changes. Machinists and CNC operators install this collet as part of routine toolsetting operations.

This collet is suited for use in production and job-shop environments where ER32 toolholding is standard. Typical applications include end milling, drilling, reaming, and tapping operations where precise tool runout and consistent clamping force are required. The 0.438-inch capacity makes it appropriate for holding common shank sizes in that range. It is packaged individually and is a direct-fit component for any spindle or chuck assembly rated for the ER32 collet series.

Installation Notes

ER32 collets are installed by machinists and CNC operators during toolsetting procedures. Before installation, ensure the spindle is fully stopped and all machine motion has ceased. The collet should be seated correctly in the collet nut before threading onto the chuck body, and the nut should be tightened using the appropriate ER collet wrench to avoid cross-threading or improper seating. Inspect the collet bore and chuck taper for chips or debris before each use to maintain runout accuracy.
