Techniks CAT40ER32-2.76 ER32 Collet Chuck CAT40

Product Description

The TECHNIKS CAT40ER32-2.76 is a CAT40 taper shank ER32 collet chuck designed for use in CNC machining centers. It accepts ER32 collets with a capacity range from 1/16 inch to 0.788 inches, making it suitable for a wide range of cutting tool shanks. With a 2.76-inch projection and an overall length of 5.45 inches, this chuck positions tooling at a consistent, repeatable gauge length. The nut tightening torque is specified at 100 foot-pounds. Licensed machinists and toolroom professionals install this chuck as part of a modular toolholding setup.

This collet chuck is used in vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. It is a standard choice for milling, drilling, reaming, and tapping operations where ER32 collets are the preferred workholding system. The 2.76-inch projection suits applications that require moderate tool reach without excessive overhang. This holder does not feature through-coolant capability, so it is best suited for operations where external or flood coolant delivery is used.

Key Features

• CAT40 taper shank for direct mounting in CAT40 CNC spindles
• ER32 collet system accepts tool shanks from 1/16 inch to 0.788 inches
• 2.76-inch projection for consistent gauge length in standard reach applications
• 5.45-inch overall length for predictable setup in machining center tool libraries
• Nut tightening torque rated at 100 foot-pounds for secure collet clamping
• No through-coolant - suited for external or flood coolant environments

Compatibility

Designed for use with ER32 collets in CAT40 spindle machining centers. Compatible with the standard ER32 collet series across common tooling systems.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Before installing or removing the chuck, the machine spindle must be fully stopped and the machine placed in a safe, locked-out state per shop lockout/tagout procedures. Use a proper ER collet chuck wrench and spanner to tighten the collet nut to the specified torque of 100 foot-pounds - do not over-torque or use impact tools. Inspect the taper and collet bore for chips or debris before seating the holder in the spindle.
