Parlec ER11-500-6H ER11 Collet Chuck Straight Shank

Product Description

The PARLEC ER11-500-6H is an ER11 series collet chuck with a straight shank, designed for precision tool holding in CNC machining centers and milling applications. It accepts ER11 collets with a capacity range of 0.50 mm to 7.00 mm (0.0197 to 0.2756 inches), making it suited for small-diameter end mills, drills, and reamers. The chuck features through-coolant delivery via a through-spindle coolant path and holds a TIR of 0.0002 inches, supporting tight-tolerance work. Overall length is 6.75 inches with a 1.25-inch projection and a 0.5-inch straight shank. Installed by machinists and CNC setup technicians in production and toolroom environments.

This collet chuck is intended for use in machining centers and CNC mills equipped with straight-shank spindle interfaces. The 0.5-inch straight shank and 5.50-inch shank length allow for secure clamping in standard hydraulic or mechanical toolholders. The through-spindle coolant feature directs coolant to the cutting edge, extending tool life and improving chip evacuation during deep or high-feed operations. It is a practical choice for shops running small-diameter tooling where runout control and coolant delivery are priorities.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is powered down and fully stopped before mounting or removing the chuck. Verify the straight shank bore and retention mechanism in the machine are clean and free of chips before seating the tool. Confirm through-coolant passages are clear and compatible with the machine spindle coolant system before operating.
