Seco 75042064 ER16 Collet 2mm Bore Toolholding

Product Description

The SECO 75042064 is an ER16-series collet designed for precision workholding in CNC milling, drilling, and tapping applications. With a 2 mm bore diameter and a total indicated runout (TIR) of 0.01 mm (0.000394 inches), this collet delivers the dimensional accuracy that machining operations demand. The overall length is 27 mm and the overall diameter is 17 mm. It is manufactured to ER16 standard specifications and seats in any ER16-compatible collet chuck. Installation and tool changes are performed by qualified machinists or toolroom technicians during setup.

This collet is suited for light-duty precision work involving 2 mm shank cutting tools such as end mills, drills, reamers, and taps. It fits standard ER16 collet chucks used on CNC machining centers, manual knee mills, high-speed spindles, and toolroom equipment. Through-coolant is not supported by this collet. It is sold individually and is well suited for shops maintaining a spare inventory of precision collets across the ER series.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before changing collets. Inspect the collet bore, seating taper, and chuck nut for chips, wear, or damage before assembly. Tighten the collet nut to the chuck manufacturer's recommended specification using the appropriate ER16 spanner wrench — do not use pipe wrenches or makeshift tools that can damage the nut or collet seating surface.
