Accupro 784823 ER32 Collet 0.278 Inch

Product Description

The ACCUPRO 784823 is an ER32 series collet designed for use in CNC machining centers, manual milling machines, and other rotating spindle equipment that accept ER32 toolholding systems. With a collet size of 0.278 inches and a minimum collet capacity of 0.25 inches, this collet grips tool shanks securely within its clamping range. The overall length is 1.575 inches. Machinists and toolroom technicians install this collet into an ER32 nut and chuck body to hold drills, end mills, reamers, and other round-shank cutting tools during machining operations.

This collet is suited for general-purpose metalworking and machining applications in production shops, tool rooms, and maintenance facilities. It is appropriate for use on knee mills, vertical machining centers, and horizontal machining centers equipped with ER32-compatible chucks or collet holders. The 0.278-inch size accommodates specific fractional or letter-size tool shanks that fall within its stated clamping range.
