Techniks 22227F ER16 Collet Chuck CAT40 Taper Shank

Product Description

The TECHNIKS 22227F is an ER16 collet chuck designed for CNC machining centers using a CAT40 taper shank interface. It accepts ER16 collets with a capacity range from 1/16 inch up to 0.406 inches, making it suitable for a wide range of small-diameter tooling. The chuck features a 4-inch projection from the gage line and an overall length of 6.68 inches. Through-coolant capability allows cutting fluid to be delivered directly to the tool tip, supporting higher feed rates and extended tool life in production environments. Machinists and CNC setup technicians install this chuck in vertical and horizontal machining centers.

The 22227F is used in production and job-shop machining operations where consistent tool runout and reliable coolant delivery are required. It is suited for drilling, reaming, tapping, and light milling applications using ER16 collets. The 4-inch projection provides clearance for workpiece features that require additional reach beyond standard stub-length holders. This chuck is a common choice for shops running CAT40-spindle vertical machining centers on ferrous and non-ferrous materials.

Compatibility

Designed for use with ER16 collets in CAT40-spindle machining centers. Accepts standard ER16 collets within the stated capacity range.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the chuck. Use a calibrated torque wrench to tighten the ER collet nut to the specified torque value. Inspect the taper shank and spindle bore for chips or damage before seating the chuck to ensure proper contact and runout performance.
