Techniks 29004 Shrink-fit Tool Holder CAT40 Taper Shank

Product Description

The TECHNIKS 29004 is a shrink-fit tool holder adapter designed for CNC machining centers equipped with a CAT40 taper spindle. It accepts tooling through an induction shrink-fit process, creating a high-strength, concentricity-critical connection between the spindle and cutting tool. The adapter features a 5-inch projection, a 0.36-inch nose diameter, and through-coolant capability to direct cutting fluid directly to the tool tip. Overall length is 7.69 inches. Machinists, CNC programmers, and toolroom technicians use this holder where rigid, low-runout tool clamping is required in production environments.

The 29004 is suited for high-speed and high-precision milling, drilling, and reaming operations in job shops and production facilities running CAT40-spindle machining centers. The through-coolant path supports chip evacuation and heat management when cutting ferrous and non-ferrous materials at elevated feeds and speeds. The 5-inch projection provides clearance for deep-cavity or tall-fixture applications where standard-length holders would not reach.

Key Features

• CAT40 taper shank for direct spindle mounting on CAT40-equipped machining centers
• 5-inch projection for deep-cavity and extended-reach applications
• 0.36-inch nose diameter accommodates small-diameter shrink-fit tooling
• Through-coolant design delivers fluid directly to the cutting zone
• Shrink-fit clamping method provides high concentricity and minimal runout
• Overall length of 7.69 inches for tool length offset planning

Compatibility

Designed for use with CAT40-spindle CNC machining centers requiring shrink-fit tool holders with through-coolant capability. Specific machine compatibility depends on spindle coolant-through pressure ratings and induction heater specifications used during tool installation.

Installation Notes

Installation requires a shrink-fit induction heater sized for the nose diameter of this holder - never use open flame to expand the bore. Ensure the spindle is powered down and the machine is in a safe, locked-out state before mounting or removing the holder. Follow the machining center manufacturer's drawbar torque procedure for CAT40 retention knobs. Verify through-coolant fittings and pressure ratings are compatible with the machine spindle before use.
