Accupro ER11HP 03.96 ER11 Collet 5/32 Inch

Product Description

The ACCUPRO ER11HP 03.96 is a precision ER11 series collet designed for CNC machining applications requiring accurate tool holding at small bore sizes. This collet accepts a 5/32 inch shank diameter and delivers a total indicator runout (TIR) of 0.0002 inches (0.0050 mm), making it suitable for high-precision milling, drilling, and engraving operations. The overall length is 18.0 mm. Machinists and CNC operators install this collet into compatible ER11 collet chuck bodies to secure cutting tools during light-duty to medium-duty machining. It is a direct replacement or spare for shops running ER11 toolholding systems.

This collet is used in CNC machining centers, CNC routers, and engraving machines equipped with ER11 collet chucks. It is well suited for small-diameter tooling applications in both production and prototype environments. The 5/32 inch bore targets specific shank sizes common in engraving cutters, small-diameter end mills, and PCB routing bits. Both professional machinists and tool room technicians rely on ER11 collets for repeatable tool changes and consistent runout performance.

Key Features

• 5/32 inch bore diameter for small-shank cutting tools
• TIR of 0.0002 inches (0.0050 mm) for high-precision toolholding
• Overall length of 18.0 mm for compact spindle configurations
• Single-piece per package for individual replacement or fleet stocking

Compatibility

Designed as an OEM-style replacement or spare for CNC machining setups using ER11 series collet chuck bodies accepting a 5/32 inch tool shank diameter.

Installation Notes

Installation and removal of ER11 collets should be performed by a qualified machinist or CNC technician. Power down and lock out the machine spindle before handling any collet or toolholder. Use the appropriate ER11 collet nut and spanner wrench to seat and torque the collet chuck assembly according to the chuck manufacturer specifications. Inspect the collet bore and seating surfaces for debris or wear before each installation to maintain TIR performance.
