Techniks 08332-1/2 ER32 Collet 1/2 Inch

Product Description

The TECHNIKS 08332-1/2 is an ER32 series collet sized at 1/2 inch (0.5000 inch decimal) for use in ER32-compatible toolholders on CNC machining centers, manual mills, and lathes. It delivers a Total Indicator Runout (TIR) of 0.0002 inch, providing the concentricity required for precision drilling, reaming, and milling operations. Through-coolant capability allows cutting fluid to pass directly through the collet to the tool tip, supporting high-speed and deep-hole machining applications. This collet is installed by machinists and CNC setup technicians working in production and job-shop environments.

The 08332-1/2 is suited for light to heavy material removal in ferrous and non-ferrous applications where accurate tool-holding is critical. Its ER32 designation means it seats in any standard ER32 collet chuck or toolholder, making it a common replacement and spare for production cells running 1/2 inch shank tooling. The 2-inch overall length (OAL) and 1-inch overall diameter fit within the standard ER32 collet range specifications.

Key Features

• ER32 collet series - fits any standard ER32 collet chuck or nut
• 1/2 inch (0.5000 inch) collet size for direct shank-tool clamping
• TIR of 0.0002 inch for precision concentricity in close-tolerance work
• Through-coolant design channels cutting fluid directly to the tool tip
• 2-inch OAL and 1-inch overall diameter within standard ER32 dimensions

Compatibility

Designed for use with standard ER32 collet chucks and toolholders accepting 1/2 inch collets.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Before installing or changing collets, de-energize the machine and ensure the spindle is fully stopped. Seat the collet into the ER32 collet nut before threading onto the toolholder, and torque the nut with the appropriate ER collet wrench to manufacturer-specified procedure. Inspect the collet bore and seating surfaces for chips or debris before assembly to protect TIR performance.
