Rego-fix 1116.02500 ER16 Collet 2.5 Mm Bore

Product Description

The REGO-FIX 1116.02500 is an ER16 precision collet bored to 2.5 mm, designed for secure tool clamping in ER16-compatible collet chucks used on CNC machining centers, milling machines, lathes, and high-speed spindles. With a total indicated runout (TIR) of 0.0004 inches, this collet delivers the concentricity required for finish milling, drilling, reaming, and tapping operations where tool deflection and runout directly affect part tolerance. The overall length is 27.5 mm with a 17 mm overall diameter, keeping the collet compact and suited for close-clearance setups. Machinists, toolroom technicians, and CNC setup personnel are the primary users of this component.

This ER16 collet is appropriate for use in light-duty to medium-duty cutting applications across job shops, production machining environments, and toolroom operations. It accommodates tool shanks at the 2.5 mm nominal bore size and fits any ER16 collet chuck or collect holder conforming to the ER16 standard. Typical applications include holding carbide or HSS end mills, drills, and reamers in vertical and horizontal machining centers.

Key Features

• ER16 collet standard for broad compatibility with ER16-rated chucks and holders
• 2.5 mm bore diameter for precise shank retention at that tool size
• TIR of 0.0004 inches for high concentricity in finish and precision operations
• 27.5 mm overall length and 17 mm overall diameter for compact installation
• Single-piece package quantity suitable for individual replacement or tooling inventory

Compatibility

Designed for use with ER16-standard collet chucks and toolholders accepting ER16 collets. Compatible with tool shanks at the 2.5 mm nominal bore diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing the collet, ensure the machine spindle is fully stopped and any CNC program is in a safe-hold state. Seat the collet into the chuck nut before threading onto the holder body to prevent collet damage. Inspect the collet bore and chuck taper for chips or contamination prior to assembly, as debris directly degrades runout performance.
