Techniks 04232-19.5 ER32 Collet 19.5mm

Product Description

The TECHNIKS 04232-19.5 is an ER32 series collet designed for precision CNC machining and toolholding applications. It holds a 19.5mm collet size and delivers a Total Indicator Runout (TIR) of 0.0002 inches (0.005mm), making it suitable for close-tolerance work where tool concentricity directly affects surface finish and tool life. The collet features through-coolant capability, allowing cutting fluid to pass directly through the bore to the cutting zone. With an overall length (OAL) of 2 inches and a weight of 0.5 pounds, it is a standard-profile collet compatible with ER32-spec toolholders. Installation is performed by qualified machinists or toolroom technicians.

This collet is used in vertical machining centers, CNC mills, and manual milling machines equipped with ER32-compatible collet chucks or toolholders. The through-coolant design is particularly well-suited for deep-pocket milling, drilling, and reaming operations where flood coolant cannot reach the cutting edge efficiently. The 19.5mm bore size accommodates shanks at that nominal metric diameter, and the tight TIR spec supports high-speed and precision finishing cuts across ferrous and non-ferrous materials.

Key Features

• ER32 collet series for use with standard ER32 collet chucks and holders
• 19.5mm collet bore size for metric shank tooling
• TIR of 0.0002 inches (0.005mm) for precision concentricity
• Through-coolant capable for direct coolant delivery to the cutting zone
• 2-inch overall length (OAL) - standard ER32 profile
• Lightweight at 0.5 pounds for easy handling during toolchange

Compatibility

Designed as a standard ER32-specification collet for use with ER32 collet chucks and toolholders on CNC and manual milling machines.

Installation Notes

Installation is performed by machinists or toolroom technicians using an appropriate ER32 collet nut and spanner wrench. Always ensure the collet chuck and collet bore are clean and free of chips or coolant residue before seating the collet. Verify TIR with a dial indicator after clamping to confirm concentricity before beginning a cutting operation. Do not exceed the toolholder manufacturer's maximum clamping torque specification for the collet nut.
