Value Collection SC84904523 ER11 Collet Chuck Straight Shank

Product Description

The VALUE COLLECTION SC84904523 is an ER11 collet chuck with a straight shank, designed for use in CNC machining centers, milling machines, and lathes. It accepts ER11 series collets and covers a clamping capacity range of 0.019 to 0.276 inches, making it suitable for a wide range of small-diameter tooling. The chuck holds a total indicator runout (TIR) of 0.0004 inches, supporting precision work where concentricity is critical. With a 5/8-inch shank diameter and a shank length of 6.67 inches, it fits standard spindle configurations used in production and tool-room environments. Installation requires a wrench-actuated collet nut. No through-coolant provision is included.

This ER11 collet chuck is used in light-duty to medium-duty machining applications where precise tool holding is required. It is well suited for high-speed milling, drilling, reaming, and tapping operations in both manual and CNC setups. The straight shank design allows direct mounting into spindles or tool holders configured for straight-shank chucks. Machinists and CNC setup technicians working in job shops, production facilities, and tool rooms are the primary installers and users of this type of tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician familiar with collet chuck tooling. Always power down and lock out the machine spindle before installing or removing the chuck. Use the correct wrench size on the collet nut hex to avoid damaging the nut or chuck body. Verify TIR with a dial indicator after installation before beginning any cutting operation.
