Techniks 22311 ER32 Collet Chuck CAT50 Taper Shank

Product Description

The TECHNIKS 22311 is an ER32 collet chuck with a CAT50 taper shank, designed for use in CNC machining centers that require precise tool holding with a standard ER collet system. The chuck features a 4-inch projection from the spindle face and an overall length of 8 inches, making it well-suited for applications where reach is needed without sacrificing rigidity. It accepts ER32 collets with a clamping range from 1/16 inch to 3/4 inch, covering a wide variety of drill, end mill, and reamer shank sizes. Machinists and tooling technicians install this chuck as a direct mount in CAT50 spindle toolholders. Coolant-through capability is not included on this model.

This collet chuck is used in vertical and horizontal machining centers equipped with CAT50 spindle interfaces. It is appropriate for production and job-shop environments where repeatable tool runout and secure clamping are required across a range of cutting tool diameters. The 4-inch projection provides clearance for deep-pocket machining and workholding setups that require additional reach. It is a solid choice for shops running ER32 tooling systems who need a reliable CAT50 interface without through-spindle coolant.

Key Features

• CAT50 taper shank for direct mounting in standard CAT50 spindles
• ER32 collet system accepts shank diameters from 1/16 inch to 3/4 inch
• 4-inch projection provides extended reach for deep-pocket and complex-fixture applications
• 8-inch overall length for balanced tool assembly planning
• No through-coolant port - suited for dry or flood coolant setups using external nozzles

Compatibility

Designed for use with ER32 series collets in machining centers with a CAT50 spindle interface. Compatible with any standard ER32 collet within the 1/16 inch to 3/4 inch clamping range.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machining center spindle before mounting or removing the chuck. Use a calibrated torque wrench and the appropriate ER32 spanner nut wrench to seat collets to the manufacturer-recommended procedure - do not over-tighten or impact the nut. Verify runout with a dial indicator after mounting before returning the spindle to service.
