Accupro 587365 ER32 Collet 0.275 Inch 7.00mm

Product Description

The ACCUPRO 587365 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accepts ER32 toolholding systems. It holds workpieces and cutting tools with a collet size of 0.275 inches (7.00mm) and delivers a Total Indicated Runout (TIR) of 0.01mm, making it suitable for precision cutting and finishing operations. Machinists and CNC operators rely on ER-series collets for their clamping consistency and broad compatibility across spindle brands. This collet weighs 1 pound and is sold individually.

This collet fits standard ER32 collet chucks used in vertical and horizontal machining centers, lathes with live tooling, and manual mills. It is appropriate for light to medium material removal in ferrous and non-ferrous applications. The 0.275-inch bore accommodates round-shank cutting tools and workpieces within the specified capacity range. Minimum collet capacity is 0.236 inches (6.0mm), allowing clamping across a small range beneath the nominal collet size. Typical users include CNC machinists, tool-and-die makers, and precision machine shop technicians.

Key Features

• ER32 collet series for use in standard ER32 chucks and collet holders
• Nominal collet size of 0.275 inches (7.00mm)
• Minimum collet capacity of 0.236 inches (6.0mm) for clamping flexibility
• 0.01mm TIR for precision runout control in finishing and tight-tolerance operations
• Single-piece packaging suitable for individual replacement or tooling builds

Compatibility

Designed as an OEM-style replacement or tooling addition for any spindle setup accepting standard ER32 collet chucks. Compatible with ER32 collet chuck bodies from common toolholding systems used in CNC mills, machining centers, and lathe turrets.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Always power down and lock out the spindle drive before inserting or removing collets. Inspect the collet bore and chuck taper for chips, burrs, or debris before seating the collet to maintain TIR accuracy. Use a calibrated torque wrench with the appropriate ER32 spanner nut to seat the collet properly and avoid over-tightening, which can damage the collet or chuck bore.
