Techniks 04216-03 ER16 Collet 3.00 Mm

Product Description

The TECHNIKS 04216-03 is an ER16 collet designed for precision workholding in CNC machining, milling, drilling, and tapping applications. Sized at 3.00 mm, it seats into any ER16-compatible collet chuck and provides a total indicated runout (TIR) of 0.0050 mm, making it suitable for close-tolerance toolholding work. At 0.1 pounds, it is a lightweight, single-piece collet sold individually. Machinists and toolroom technicians rely on ER-series collets for their consistent clamping force and broad compatibility across spindle systems that accept the ER16 standard.

This collet is used in vertical and horizontal machining centers, benchtop mills, CNC routers, and drill-tap machines where an ER16 collet chuck is installed. It is appropriate for production shops, toolrooms, and precision machine shops running small-diameter cutting tools. The 3.00 mm bore suits standard metric shank tooling including end mills, drills, and reamers of that diameter.

Key Features

• ER16 collet series for use with ER16-compatible collet chucks
• 3.00 mm collet bore for metric shank tooling
• TIR of 0.0050 mm for close-tolerance toolholding
• Lightweight at 0.1 pounds
• No through-coolant - solid collet construction
• Sold individually (quantity of one)

Compatibility

Designed as a direct-fit replacement or spare for any ER16-standard collet chuck accepting a 3.00 mm collet.

Installation Notes

Installation is performed by machinists or toolroom technicians following standard ER collet chuck procedures. Ensure the collet chuck and spindle are fully de-energized and the machine is locked out before changing collets. Seat the collet into the nut before threading onto the chuck body, and torque the nut to the chuck manufacturer's specified value using an ER collet wrench. Inspect the collet for wear, nicks, or debris before each use to maintain TIR performance.
