Value Collection 204-3232 ER32 Collet 0.5 Inch

Product Description

The VALUE COLLECTION 204-3232 is an ER32 series collet designed to hold 0.5 inch diameter tooling in compatible ER32 collet chucks. It delivers a total indicated runout (TIR) of 0.0005 inches, providing the concentricity and grip precision required for milling, drilling, reaming, and tapping operations. Weighing 0.35 pounds, this collet is a standard workholding component used by machinists and tool and die technicians on CNC machining centers, vertical mills, and manual knee mills. The ER32 collet design uses a slotted, spring-type body that compresses uniformly when the collet nut is tightened, ensuring secure tool engagement across the full clamping range.

This collet is suited for production and maintenance machining environments where accurate tool holding in an ER32 chuck is required. Typical applications include holding end mills, drill bits, reamers, and taps at the 0.5 inch shank diameter. It fits any ER32-standard collet chuck body, making it a practical replacement or supplemental collet for shops running ER32 tooling systems on CNC or manual machine platforms.

Key Features

• ER32 collet series for use with ER32-compatible chuck bodies
• 0.5 inch (1/2 inch) collet bore diameter for standard shank tooling
• 0.0005 inch TIR for consistent tool concentricity
• Spring-slotted body provides uniform radial clamping force
• Lightweight at 0.35 pounds for easy handling and tool changes

Compatibility

Designed as an OEM-style replacement or supplemental collet for use with ER32-standard collet chuck bodies on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before inserting or removing the collet, confirm the spindle is fully stopped and the machine is powered down or in an E-stop state. Seat the collet into the collet nut before threading the nut onto the chuck body, and use a proper ER collet wrench and chuck-holding tool to achieve adequate clamping torque without over-tightening. Inspect the collet bore and chuck taper for chips or contamination before each use, as debris will degrade runout performance.
