Accupro ER32HP 07.93 ER32 Collet 5/16 Inch

Product Description

The ACCUPRO ER32HP 07.93 is a precision ER32-series collet designed for CNC machining centers, milling machines, and other rotating spindle applications. This collet accepts 5/16-inch shank tooling and delivers a total indicator runout (TIR) of 0.0002 inches (0.005 mm), making it suitable for operations where close concentricity tolerances are required. The overall length is 40.0 mm. Machinists, CNC operators, and tool-room technicians install this type of collet as part of a standard ER32 collet chuck system to securely grip cutting tools, drills, reamers, and end mills during high-speed operation.

The ER32HP 07.93 fits standard ER32 collet chuck bodies used across a wide range of machining platforms. It is appropriate for both production and job-shop environments where 5/16-inch tooling is common. Typical applications include milling, drilling, tapping, and reaming operations on ferrous and non-ferrous workpieces. This collet is sold individually and is stocked as a direct replacement or supplemental addition to an existing ER32 tooling setup.

Key Features

• ER32 collet series for use with standard ER32 collet chuck bodies
• 5/16-inch bore accepts standard 5/16-inch shank cutting tools
• Low TIR of 0.0002 inches (0.005 mm) supports tight concentricity requirements
• 40.0 mm overall length fits standard ER32 chuck geometry
• Lightweight at 0.35 pounds for easy handling and quick changeover

Compatibility

Designed as a direct-fit replacement or supplemental collet for standard ER32 collet chuck systems accepting 5/16-inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before inserting or removing a collet, the machine spindle must be fully stopped and the machine placed in an appropriate lockout state per shop safety protocols. The collet should be seated correctly in the collet nut before threading onto the chuck body to prevent damage to the collet taper. Torque the collet nut using an appropriate ER32 collet nut wrench to achieve proper clamping force without overloading the collet or chuck threads.
