Techniks 29013 Shrink-fit Tool Holder Adapter CAT40

Product Description

The TECHNIKS 29013 is a shrink-fit tool holder adapter designed for CNC machining centers equipped with a CAT40 taper spindle. It secures cutting tools through thermal shrink-fit clamping, delivering high concentricity and rigidity compared to collet-style holders. The adapter features a 5-inch projection, a 0.71-inch nose diameter, and a 1/4-inch hole diameter for tool retention. Through-coolant capability channels cutting fluid directly to the tool tip, supporting extended tool life and chip evacuation in demanding cutting applications. At 2.84 pounds, the holder is sized for standard CAT40 tooling setups. Installation is performed by qualified CNC machinists or toolroom technicians.

This adapter is suited for use in vertical and horizontal machining centers with CAT40 spindle interfaces. The 5-inch projection makes it appropriate for applications requiring extended reach, such as deep-cavity milling, die and mold work, or multi-fixture setups where clearance is limited. The through-coolant feature is particularly useful in high-speed finishing and semi-finishing operations where heat management at the cutting zone is critical. The 1/4-inch bore accommodates small-diameter end mills and drills commonly used in precision machining work.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle interfaces
• 5-inch projection for extended reach in deep-cavity and complex-geometry applications
• Through-coolant design directs cutting fluid to the tool tip for improved chip evacuation and tool life
• 0.71-inch nose diameter provides a slim profile for tight-clearance cutting environments
• 1/4-inch hole diameter accommodates small-diameter cutting tools
• Shrink-fit clamping delivers high concentricity and radial rigidity for precision cutting

Compatibility

Designed as an OEM-style shrink-fit tool holder adapter for CNC machining centers with a CAT40 taper spindle interface and through-coolant capability.

Installation Notes

Shrink-fit tool holders require a dedicated induction heating unit to expand the bore before tool insertion and removal - never attempt to press or force a cutting tool without proper thermal expansion. Power down the machining center and release spindle air pressure before removing or installing any tool holder. Verify through-coolant port alignment with the spindle coolant supply before operation. Installation should be performed by a qualified CNC machinist or toolroom technician familiar with shrink-fit tooling systems.
