Featuring a CAT40 taper shank, this adapter accepts cutting tools with a 0.25 inch bore diameter and delivers a 4.63 inch projection length. The nose diameter measures 0.433 inches with a clamping depth of 0.95 inches. Built for demanding production environments, the 4504612 supports balanced operation up to 25,000 RPM and includes through-coolant capability to maintain cutting temperatures and extend tool life during high-speed operations. Machinists and tool crib personnel working on precision milling and boring applications rely on this type of holder for consistent, repeatable runout performance.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for use in vertical and horizontal machining centers equipped with CAT40 spindle interfaces. It is a practical choice for shops running high-speed finishing passes or tight-tolerance boring operations where spindle balance and coolant delivery at the cutting edge are required. The through-coolant feature makes it particularly well-suited for deep-pocket milling or drilling where flood coolant cannot reach the cutting zone effectively.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for secure spindle interface on compatible machining centers\u003c\/li\u003e\n\u003cli\u003e0.25 inch hole diameter accommodates standard quarter-inch shank cutting tools\u003c\/li\u003e\n\u003cli\u003e4.63 inch projection length for extended reach applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design channels fluid directly to the cutting zone\u003c\/li\u003e\n\u003cli\u003eBalanced to 25,000 RPM for high-speed machining stability\u003c\/li\u003e\n\u003cli\u003e0.95 inch clamping depth ensures firm, concentric tool grip after induction shrink-fit process\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style shrink-fit tool holder adapter for CAT40 spindle machining centers accepting 0.25 inch shank cutting tools with through-coolant capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShrink-fit tool holders require an induction heating unit to expand the bore before tool insertion and must be allowed to cool fully before use. Power down and de-energize the machining center before any tooling changes at the spindle. Follow the machine tool builder guidelines and applicable OSHA lockout\/tagout procedures during installation. Do not attempt to seat or remove cutting tools from a shrink-fit holder without proper induction equipment, as cold-pressing can damage the bore geometry.\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\u003eHole Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection Length\u003c\/strong\u003e: 4.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 0.433 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4504612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750717554994,"sku":"4504612","price":539.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39c0be49ba6aa3aba799c9e47290bf16_043faf48-0423-4b6a-8d24-b42e5b3df8c0.jpg?v=1788918937","url":"https:\/\/voomisupply.com\/products\/iscar-4504612-shrink-fit-tool-holder-adapter-cat40","provider":"Voomi Supply","version":"1.0","type":"link"}
