It features a 1-1\/2 inch pilot diameter and an overall length of 7.338 inches, with a projection from flange to nose end of 2.4 inches. The holder supports through-spindle coolant delivery as well as DIN flange coolant porting, making it compatible with machine tools equipped with either coolant system configuration. Balanced to 12,000 RPM, this holder suits applications where speed and precision are both critical. It is installed by machinists and tooling specialists in job shop and production machining environments.\u003c\/p\u003e\n\u003cp\u003eThis shell mill holder is suited for use on CAT50-spindle vertical and horizontal machining centers running face mills, shell mills, and other flange-mount cutters. The 3\/4-16 lock screw thread accommodates standard arbor screw sizes used with common shell mill body designs. The 3.81 inch nose diameter provides a stable mounting face for large-diameter cutters used in facing, slotting, and high-volume material removal operations in ferrous and non-ferrous applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCAT50 taper shank for direct mount in CAT50 spindle machines\u003c\/li\u003e\n  \u003cli\u003eThrough-spindle and DIN flange dual coolant delivery support\u003c\/li\u003e\n  \u003cli\u003eBalanced to 12,000 RPM for stable high-speed operation\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch pilot diameter with 3.81 inch nose diameter for large cutter support\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 lock screw thread for standard shell mill arbor screw compatibility\u003c\/li\u003e\n  \u003cli\u003eOverall length of 7.338 inches with 2.4 inch flange-to-nose projection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CAT50-spindle CNC machining centers equipped with through-spindle coolant or DIN flange coolant systems and shell mill or face mill cutter bodies using a 3\/4-16 arbor lock screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. The machine spindle must be fully powered down and locked out before mounting or removing the holder. CAT50 taper interfaces should be inspected for debris, nicks, and wear prior to seating the holder; the taper bore and holder shank should be clean and dry unless machine tooling procedures specify otherwise. Drawbar torque should follow the machine tool builder specifications for CAT50 retention knobs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: CAT50 Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.338 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection Flange to Nose End\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 3.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Thread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Type\u003c\/strong\u003e: Through-Spindle and DIN Flange\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: 12,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.87 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3640216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730767872306,"sku":"3640216","price":357.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11ca367aa1d92c860f2a4710780ab1e3_35aae642-40ee-4f10-ac49-aad2b221b2ae.jpg?v=1788722541","url":"https:\/\/voomisupply.com\/products\/kennametal-3640216-shell-mill-holder-cat50-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
