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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct spindle mounting on CAT40-equipped machining centers\u003c\/li\u003e\n\u003cli\u003e5-inch projection for deep-cavity and extended-reach applications\u003c\/li\u003e\n\u003cli\u003e0.36-inch nose diameter accommodates small-diameter shrink-fit tooling\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design delivers fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003eShrink-fit clamping method provides high concentricity and minimal runout\u003c\/li\u003e\n\u003cli\u003eOverall length of 7.69 inches for tool length offset planning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CAT40-spindle CNC machining centers requiring shrink-fit tool holders with through-coolant capability.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.45 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TECHNIKS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 29004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":67581781934386,"sku":"29004","price":307.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e1dbdf4d7a370d84953162bad97f904_0a14a4ae-794d-4df6-b277-52a787bb0129.jpg?v=1790405970","url":"https:\/\/voomisupply.com\/products\/techniks-29004-shrink-fit-tool-holder-cat40-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
