Techniks 22352 Mini-er ER11 Collet Chuck CAT40 Taper Shank

Product Description

The TECHNIKS 22352 is a Mini-ER collet chuck with a CAT40 taper shank, designed for use in CNC machining centers and milling applications. It accepts ER11 series collets with a minimum capacity of 1/16 inch and a maximum capacity of 9/32 inch. The overall length is 5.44 inches with a projection of 2.75 inches, making it well suited for close-tolerance toolholding in tight workspaces. Installed by machinists and CNC setup technicians, this chuck provides a rigid, repeatable interface between the spindle and cutting tool for precision work.

This collet chuck is used in CNC vertical and horizontal machining centers equipped with a CAT40 spindle taper. The ER11 collet series is a compact, industry-standard system commonly applied in high-speed drilling, light milling, reaming, and tapping operations. The 2.75-inch projection suits applications where tool reach and clearance are primary considerations. Through-coolant is not supported on this unit.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Always power down and lock out the machine spindle before mounting or removing the collet chuck. Use a calibrated torque wrench and the appropriate ER11 collet nut spanner to seat the collet and nut properly. Inspect the taper shank and spindle bore for debris or damage before seating to ensure full contact and runout accuracy.
