Techniks 22213-3 ER11 Collet Chuck CAT40 Taper Shank

Product Description

The TECHNIKS 22213-3 is an ER11 collet chuck with a CAT40 taper shank, designed for use in CNC machining centers and milling applications. It accepts ER11 collets with a capacity range from 1/16 inch minimum to 0.275 inches maximum, making it suitable for gripping small-diameter cutting tools and drills. The chuck has a 3-inch projection from the gauge line and an overall length of 5.68 inches. Weighing 2.1 pounds, it is a solid, direct-mount toolholder intended for installation by machinists and CNC setup technicians working with CAT40-spindle machines.

This collet chuck is suited for CNC vertical and horizontal machining centers equipped with CAT40 spindles. It is a standard configuration for shops running small-diameter end mills, drills, reamers, or taps held in ER11 collets. The 3-inch projection provides clearance for workpiece features that require the spindle nose to stand off from the workpiece or fixture. Through-coolant is not supported on this toolholder, so it is best applied in dry-cut or flood-coolant environments where coolant is delivered externally.

Key Features

• ER11 collet system accepts cutting tools from 1/16 inch to 0.275 inches in diameter
• CAT40 taper shank for direct mounting in CAT40-spindle machining centers
• 3-inch projection for clearance in deep-pocket or fixtured setups
• 5.68-inch overall length for predictable tool-length offset programming
• No through-coolant bore - suited for external or flood coolant delivery
• UNSPSC Code 27112808 for procurement and catalog classification

Compatibility

Designed for use with standard ER11 collets in CAT40-spindle CNC machining centers. Compatible with any machine spindle conforming to the CAT40 taper standard.

Installation Notes

Installation must be performed with the machine spindle fully stopped and the control in an e-stop or toolchange state. Use a calibrated CAT40 torque wrench and the appropriate ER11 collet nut spanner to seat the collet and nut correctly - never use impact tools on collet nuts. Verify tool runout with a dial indicator after assembly before resuming cutting operations. Follow the machine manufacturer's toolholder clamping specifications for drawbar force.
