The holder features a 0.75 inch pilot diameter and a flange-to-nose projection of 1.375 inches, providing a compact, rigid setup for face milling operations. Through-spindle coolant delivery is integrated, directing coolant directly to the cutting zone to improve chip evacuation and extend insert life. Total indicated runout (TIR) is rated at 0.0002 inches, supporting accurate, repeatable cutting performance across production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis shell mill holder is suited for milling applications in aerospace, die and mold, and general machining where a CAT40 spindle is in use. The through-spindle coolant feature makes it particularly effective when running carbide shell mills on steel, cast iron, or aluminum at higher feed rates where heat and chip buildup are concerns. Licensed machinists and CNC setup technicians are the primary installers. The 0.75 inch pilot accommodates standard shell mill arbor bores of that size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank for direct mounting to CAT40 spindle interfaces\u003c\/li\u003e\n\u003cli\u003e0.75 inch pilot diameter for standard shell mill fitment\u003c\/li\u003e\n\u003cli\u003eThrough-spindle coolant delivery for improved chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003e1.375 inch flange-to-nose projection for compact setup and rigidity\u003c\/li\u003e\n\u003cli\u003eTIR of 0.0002 inches for precise, repeatable runout performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with machining centers equipped with a CAT40 spindle interface and shell mills with a 0.75 inch pilot bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machining center spindle before mounting or removing the holder. Use the appropriate CAT40 retention knob and confirm proper drawbar engagement before operation. Verify coolant passages are clear and seated correctly before enabling through-spindle coolant flow.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle\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: 1 pound\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: 4501474\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51749884559666,"sku":"4501474","price":228.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c30b3282c8c2fd597aa3e1c2e6191098.jpg?v=1788911704","url":"https:\/\/voomisupply.com\/products\/iscar-4501474-shell-mill-holder-cat40-0-75-inch-pilot","provider":"Voomi Supply","version":"1.0","type":"link"}
