It accepts a 0.25 inch bore tool shank and provides a 3 inch projection from the gage line to the cutting tool, giving machinists clearance for deep-cavity and complex-contour work. The nose diameter measures 0.71 inches, and the holder is built with through-coolant capability, allowing high-pressure coolant to reach the cutting edge directly. Overall length is 5.69 inches. This adapter is installed by toolroom technicians and CNC setup personnel who require precise, repeatable tool runout in high-speed machining applications.\u003c\/p\u003e\n\u003cp\u003eThis shrink-fit adapter is suited for use on vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. It is appropriate for production environments where consistent tool holding rigidity and minimal runout are critical, such as finishing passes on mold cavities, aerospace components, or tight-tolerance die work. Through-coolant support makes it a practical choice for drilling and reaming operations where chip evacuation and tool life are priorities. The 3 inch projection accommodates setups where standard-length holders would cause spindle or fixture interference.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank interface for compatibility with standard CAT40 spindle tooling systems\u003c\/li\u003e\n  \u003cli\u003e0.25 inch bore diameter for 1\/4 inch shank cutting tools\u003c\/li\u003e\n  \u003cli\u003e3 inch projection for extended reach in deep-cavity and complex-geometry setups\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design delivers coolant directly to the cutting zone\u003c\/li\u003e\n  \u003cli\u003e0.71 inch nose diameter for clearance in confined workpiece features\u003c\/li\u003e\n  \u003cli\u003eOverall length of 5.69 inches for predictable tool offset programming\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style shrink-fit adapter for CNC machining centers equipped with a CAT40 taper spindle interface and through-coolant capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShrink-fit tool holders require an induction heating unit to thermally expand the bore before inserting or removing cutting tools  -  never attempt to press or hammer tools into the bore. Ensure the spindle drawbar and retention knob are fully engaged and torqued to the machine manufacturer specification before running the spindle. Power down and lock out the machine before changing tooling. Through-coolant connections should be inspected for seal integrity and proper seating before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eBore Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.69 inches\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: 2.40 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 29010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52032970162482,"sku":"29010","price":275.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ffdd13be1b004efe3468a216c309d42.jpg?v=1790021219","url":"https:\/\/voomisupply.com\/products\/techniks-29010-shrink-fit-tool-holder-adapter-cat40","provider":"Voomi Supply","version":"1.0","type":"link"}
