Kennametal 1950132 ER32 Collet 5/16 Inch

Product Description

The KENNAMETAL 1950132 is an ER32 precision collet designed to hold cutting tools and workpieces in CNC machining centers, milling machines, lathes, and drilling applications. Built to the ER32 standard, it accepts a nominal tool shank diameter of 0.3125 inches (5/16 inch) with a minimum collet capacity of 0.2725 inches, allowing it to grip a range of shank sizes within that range. The collet delivers a total indicator runout (TIR) of 0.0006 inches (0.0152 mm), supporting the accuracy demanded in precision machining environments. Overall length is 1.575 inches (40.01 mm). This collet is installed by machinists, toolroom technicians, and CNC setup personnel.

The KENNAMETAL 1950132 is suited for use in any ER32-compatible collet chuck or toolholder across light to medium-duty machining operations. Typical applications include end mill holding, drill holding, reaming, and tapping in both vertical and horizontal machining centers. It is appropriate for production and job-shop environments where repeatable tool runout and consistent clamping force are required. The ER32 series is widely used in both manual and CNC machine tool setups.

Compatibility

Designed for use with ER32-standard collet chucks and toolholders. Fits any machine spindle or toolholder manufactured to the ER32 collet specification.

Installation Notes

ER32 collets are installed by machinists or CNC toolroom technicians using the appropriate ER32 collet nut and spanner wrench. Always ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Inspect the collet bore and the toolholder taper for chips, debris, or wear before seating the collet. Do not exceed the collet capacity range, as over-clamping outside the specified range can damage both the collet and the toolholder.
