This adapter features a 5-inch projection and a 0.375-inch bore diameter, making it suitable for holding shrink-fit tooling with tight concentricity tolerances. Through-coolant capability allows cutting fluid to be delivered directly to the cutting zone, supporting longer tool life and better chip evacuation during deep-pocket or high-feed operations. Machinists and CNC tool-crib technicians are the primary users of this adapter in production shop environments.\u003c\/p\u003e\n\u003cp\u003eThis adapter is applied in vertical and horizontal machining centers equipped with CAT40 spindles. The 5-inch projection provides clearance for deep-feature work or setups where the spindle nose must stand off from the workpiece or fixture. Through-coolant routing makes it a practical choice for drilling, reaming, and milling operations where flood coolant alone is insufficient. The 0.94-inch nose diameter is consistent with standard shrink-fit chuck profiles used across general-purpose and precision machining applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT40 taper shank for direct spindle mounting on standard CAT40 machining centers\u003c\/li\u003e\n  \u003cli\u003e5-inch projection for deep-feature access and fixture clearance\u003c\/li\u003e\n  \u003cli\u003e0.375-inch (3\/8 inch) bore diameter for shrink-fit tooling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs cutting fluid to the tool tip\u003c\/li\u003e\n  \u003cli\u003e0.94-inch nose diameter compatible with standard shrink-fit chuck profiles\u003c\/li\u003e\n  \u003cli\u003eOverall length of 7.69 inches for predictable stick-out calculations\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 with CAT40 taper spindles requiring a 3\/8-inch bore shrink-fit holder with through-coolant capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a shrink-fit induction heater to expand the bore before seating or removing tooling  -  never attempt to press or hammer tooling into or out of a shrink-fit bore. Power down the machining center and confirm spindle rotation is fully stopped before removing or installing the holder. Verify drawbar pull-force specifications on the machining center match CAT40 retention requirements before use. Inspect the taper shank and spindle bore for chips, burrs, or contamination prior to seating.\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\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\u003eBore Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.94 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: 3.22 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: 29023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECHNIKS","offers":[{"title":"Default Title","offer_id":52120498635058,"sku":"29023","price":307.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e1dbdf4d7a370d84953162bad97f904_50a2f912-513f-4abb-bd3a-5a1586079a95.jpg?v=1790083809","url":"https:\/\/voomisupply.com\/products\/techniks-29023-cat40-shrink-fit-tool-holder-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
