Techniks 29011 Shrink-fit Tool Holder Adapter CAT40

Product Description

The TECHNIKS 29011 is a shrink-fit tool holder adapter designed for CNC machining centers that use a CAT40 taper shank interface. It accepts a 0.25 inch bore diameter and features a 0.71 inch nose diameter, with an overall length of 6.19 inches. Through-coolant capability directs cutting fluid directly to the tool tip, supporting higher feed rates and improved chip evacuation in demanding material removal operations. This adapter is installed by machinists and CNC setup technicians in production and job-shop environments.

This shrink-fit adapter is suited for vertical and horizontal CNC machining centers equipped with a CAT40 spindle. Shrink-fit holders deliver superior concentricity and gripping force compared to collet-style holders, making them a preferred choice for high-speed finishing passes and tight-tolerance applications. The through-coolant feature is particularly useful in deep-pocket milling and drilling operations where flood coolant cannot reach the cutting zone effectively.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle tooling systems
• 0.25 inch bore diameter accommodates common shank tool sizes
• 0.71 inch nose diameter provides clearance in tight workpiece geometries
• 6.19 inch overall length suits a range of reach requirements on CNC machining centers
• Through-coolant design channels coolant directly to the cutting edge
• Shrink-fit interface delivers high clamping force and low runout for precision work

Compatibility

Designed as a direct-fit shrink-fit tool holder adapter for CNC machining centers with a CAT40 taper spindle interface.

Installation Notes

Installation requires an induction shrink-fit heater rated for the holder bore diameter. The holder must be fully cooled and dimensionally verified before tool insertion or removal to prevent damage to the bore or the cutting tool shank. Power down and lock out the machining center spindle before any tooling change. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when handling heated components.
