Kennametal 6612283 ER16 Collet 0.378 Inches

Product Description

The KENNAMETAL 6612283 is an ER16 collet designed for precision workholding in CNC machining and manual milling operations. It accepts tool shanks with a decimal inch diameter of 0.378 inches and fits standard ER16 collet chucks. Measuring 2.36 inches in length and 0.91 inches in both height and width, the collet delivers consistent concentricity and clamping force for rotating tool applications. At 0.068 pounds, it is a lightweight yet rigid component suited for high-speed spindle use. Machinists and CNC operators install this collet as part of a toolholding system to secure end mills, drills, reamers, and other round-shank cutting tools.

This ER16 collet is used in light-duty machining centers, CNC routers, manual mills, and engraving machines that accept ER16-series collet chucks. The ER16 series is a standard collet format found widely in benchtop and compact machining setups. Typical applications include precision drilling, light milling, and reaming where accurate tool runout control is required. It is sold individually and is compatible with any ER16 chuck conforming to standard ER collet geometry.

Installation Notes

ER collets are installed and removed by machining professionals using the appropriate ER16 collet nut and spanner wrench. Always power down and lock out the spindle before changing collets. Inspect the collet bore and chuck taper for debris or damage before seating. Do not exceed the rated clamping range of the collet series, as over-range use reduces clamping force and concentricity.
