Techniks 04232-19 ER32 Collet 19mm Through Coolant

Product Description

The TECHNIKS 04232-19 is an ER32 series collet designed for precision workholding in CNC machining and toolholding applications. With a 19mm collet size and a total indicator runout (TIR) of 0.005mm, this collet delivers the tight tolerances required for accurate, repeatable cutting operations. Through-coolant capability allows coolant to flow directly to the cutting zone, improving chip evacuation and tool life. Machinists and CNC operators install this collet into compatible ER32 collet chucks as part of standard toolholding setups in milling, drilling, and turning operations.

This collet is suited for use in production machining environments where consistent runout control is critical. The ER32 series is widely used in both light and heavy-duty machining centers. The 2-inch overall length (OAL) and 1-inch overall diameter make it compatible with standard ER32 chuck bodies. Through-coolant support makes it a practical choice for high-speed operations and deep-hole drilling where heat and chip buildup are concerns.

Key Features

• 19mm collet size for precise workholding
• TIR of 0.005mm for high-accuracy toolholding
• Through-coolant compatible for improved chip evacuation and tool life
• ER32 series for broad chuck compatibility
• 2-inch OAL and 1-inch overall diameter

Compatibility

Designed as an OEM-style replacement or standard fitment collet for ER32 series collet chuck bodies used in CNC milling, drilling, and turning applications.

Installation Notes

ER collets are installed and removed by machinists using an appropriate ER32 collet nut and spanner wrench. Ensure the collet chuck and spindle are fully stopped and locked out before changing collets. Inspect the collet bore and chuck taper for debris or damage before seating. Do not exceed the collet's rated clamping range to avoid workholding failures.
