Techniks 04232-13/16 ER32 Collet 13/16 Inch

Product Description

The TECHNIKS 04232-13/16 is an ER32 collet designed for precision workholding in CNC machining centers, milling machines, and collet chuck systems. Sized at 13/16 inch (0.8125 inches decimal), it holds round shank tooling within a total indicated runout (TIR) of 0.0002 inches, making it suitable for applications where concentricity directly affects finish quality and tool life. Through-coolant capability allows cutting fluid to pass axially through the collet, reaching the cutting zone during deep-bore or high-heat operations. Machinists and CNC operators install this collet as part of ER32-standard toolholding setups across production and job-shop environments.

This collet fits ER32-series collet chucks and toolholders used in standard milling, drilling, reaming, and tapping operations. The 13/16 inch bore size accommodates tooling and workpieces at that diameter. Through-coolant design makes it well suited for operations requiring directed coolant flow, including high-speed machining and materials that generate significant heat at the cutting interface. The 2-inch overall length (OAL) is consistent with standard ER32 collet geometry for common spindle and chuck configurations.

Key Features

• ER32 collet series - fits all ER32-standard collet chucks and holders
• 13/16 inch (0.8125 inches) bore size for direct shank tooling engagement
• 0.0002 inches TIR for precision concentricity in finishing and close-tolerance work
• Through-coolant design routes cutting fluid directly to the tool tip
• 2 inches overall length (OAL) matches standard ER32 collet chuck geometry

Compatibility

Designed for use with ER32-standard collet chucks and toolholders. Compatible with any spindle or chuck body that accepts the ER32 collet series at the 13/16 inch bore size.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before inserting or removing collets. Seat the collet fully into the nut before engaging the chuck body, and use a calibrated collet nut wrench torqued to the chuck manufacturer's specification - do not use improvised tools that can damage the collet taper or nut threads. Inspect the collet bore and chuck taper for debris or damage before each use, as contamination directly degrades TIR performance.
