Accupro 784806 ER32 Collet 0.153 Inch Capacity

Product Description

The ACCUPRO 784806 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other precision rotating spindle applications. It accepts a maximum tool shank diameter of 0.153 inches and a minimum collet capacity of 0.141 inches, giving a usable clamping range suited to standard end mills, drills, and reamers in that size range. The overall length is 1.575 inches. This collet is installed by machinists and CNC operators working in production and job-shop environments where secure, repeatable tool holding is critical to part quality and spindle life.

This ER32 collet fits standard ER32-compatible collet chucks and tool holders used across a wide range of machining operations including milling, drilling, boring, and tapping. The ER32 series is one of the most widely adopted collet standards in CNC and manual machining, making this collet a common replacement or supplemental tooling item in shops running metric or imperial tooling in the 0.141 to 0.153 inch diameter range.

Key Features

• ER32 collet series for compatibility with ER32 tool holders and chucks
• Clamping range from 0.141 inches minimum to 0.153 inches maximum capacity
• Overall length of 1.575 inches for standard ER32 chuck depth
• Precision ground construction for repeatable tool runout performance
• Single-piece package quantity suitable for individual replacement or tooling builds

Compatibility

Designed as a direct-fit collet for ER32-standard collet chucks and tool holders. Specific chuck or machine compatibility depends on the tool holder brand and ER32 collet seat dimensions in use. No specific machine or holder models were identified in the product data.

Installation Notes

ER32 collets are installed by machinists or CNC operators and require the spindle or tool holder to be fully de-energized and at rest before any collet change. Use the correct ER32 collet nut and a calibrated torque wrench or spanner set rated for ER-series nuts — do not over-torque the collet nut, as this can damage the collet taper or reduce clamping accuracy. Inspect the collet bore and chuck taper for chips or damage before seating the collet. Follow the machine manufacturer and applicable shop safety procedures for spindle tooling changes.
