Accupro 784775 ER32 Collet 0.528 Inch Capacity

Product Description

The ACCUPRO 784775 is an ER32 series collet designed for precision workholding in CNC milling, drilling, and tapping applications. The collet accepts a maximum clamping diameter of 0.528 inches with a minimum collet capacity of 0.516 inches, giving a usable clamping range suited to close-tolerance tool shanks. Overall length is 1.575 inches. The ER32 designation refers to the collet taper size, which follows the widely adopted DIN 6499 ER standard. Machinists and CNC setup technicians install this collet into a compatible ER32 collet chuck or toolholder to secure cutting tools, drill bits, taps, or round-shank workpieces during machining operations.

This collet is appropriate for use in ER32 collet chucks mounted in machining centers, CNC lathes with live tooling, manual mills, and drill presses equipped with ER32 toolholders. The 0.528-inch capacity targets tool shanks that fall within the 0.516-to-0.528-inch clamping range. Typical users include CNC machinists, tool-and-die technicians, and production shop setups requiring consistent, repeatable tool runout across multiple setups. The part ships individually and is sold in a minimum order quantity of one unit.

Compatibility

Designed for use with ER32 collet chucks and ER32 toolholders that accept the standard ER32 taper collet form. Specific chuck or toolholder compatibility is not stated in available product data; verify your chuck series accepts ER32 collets before ordering.

Installation Notes

ER collets are installed and removed by a licensed machinist or qualified CNC technician. Always de-energize and lock out the machine spindle before inserting or removing collets. Seat the collet fully into the collet nut before threading the nut onto the chuck body to prevent collet damage. Inspect the collet bore and chuck taper for chips or contamination before each installation, as debris directly affects runout and tool retention.
