Value Collection SC84904549 ER16 Collet Chuck Straight Shank

Product Description

The VALUE COLLECTION SC84904549 is an ER16 collet chuck designed for precision workholding in CNC machining, milling, and drilling operations. It accepts the ER16 collet series and handles tool shank diameters from 0.019 to 0.394 inches, making it suitable for a wide range of end mills, drills, and reamers. The straight shank measures 0.75 inches in diameter and 7.1 inches in length, with a total indicated runout (TIR) of 0.0004 inches for accurate, repeatable tool positioning. Actuation is wrench-driven via a collet nut with a hex diameter of 13/16 inch. At 0.726 pounds, this chuck is a compact, reliable toolholding solution for machine shop and production environments.

This ER16 collet chuck is suited for use in vertical and horizontal machining centers, manual mills, and CNC lathes equipped with a straight-shank spindle interface. The 0.75-inch straight shank fits standard spindle bores and quick-change toolholding systems that accept straight-shank holders. It is commonly installed by machinists and CNC operators in job shop, production, and maintenance machining settings where consistent tool runout and secure clamping across a broad capacity range are required.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and locked out before inserting or removing the chuck. Use the appropriate ER16 collet nut wrench and spanner to achieve proper clamping torque; do not use impact tools on the collet nut. Verify TIR after installation using a dial test indicator before beginning production runs.
