It accepts a 1-inch bore and features through-coolant capability, supporting both through-spindle and through-bore coolant paths as well as DIN flange configurations. With a nose diameter of 2 inches, a projection of 2.62 inches, and a clamping depth of 2.5 inches, this holder is suited for rigid, repeatable tool setups in production milling applications. It is balanced to 8,000 RPM and holds a TIR of 0.002 inches, making it appropriate for moderate to high-speed finishing and semi-finishing operations.\u003c\/p\u003e\u003cp\u003eThis end mill holder is used in horizontal and vertical CNC machining centers equipped with CAT50 spindles. It is a common choice in heavy-duty production environments such as aerospace, automotive, and general manufacturing shops running larger-diameter end mills or shell mills that demand stable clamping and consistent coolant delivery to the cutting zone. The 2.62-inch projection provides adequate clearance for most standard tooling setups without excessive overhang. Licensed machinists and tooling technicians typically specify this holder when through-coolant capability and balanced high-speed performance are required in a CAT50 platform.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT50 taper shank for direct mounting in CAT50-spindle machining centers\u003c\/li\u003e\n\u003cli\u003e1-inch bore diameter with 2.5-inch clamping depth for secure end mill retention\u003c\/li\u003e\n\u003cli\u003eThrough-coolant support via through-spindle, through-bore, and DIN flange paths\u003c\/li\u003e\n\u003cli\u003eBalanced to 8,000 RPM for stable high-speed milling operations\u003c\/li\u003e\n\u003cli\u003eTIR of 0.002 inches for consistent tool runout control\u003c\/li\u003e\n\u003cli\u003e2-inch nose diameter and 2.62-inch projection for clearance flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style end mill holder for CNC machining centers with a CAT50 taper spindle interface accepting 1-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician with the machine powered down and spindle locked. Use a properly rated CAT50 pull stud and torque the retention knob according to the machine tool manufacturer specifications. Inspect the taper shank and spindle bore for chips, burrs, or contamination before seating the holder. Verify coolant line connections and through-spindle pressure settings match the machine and tooling requirements before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: CAT50 Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 2.62 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.0079 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR\u003c\/strong\u003e: 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced To\u003c\/strong\u003e: 8,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes — Through-Spindle, Through-Bore, and DIN Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.73 inches L x 4.53 inches W x 4.53 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.17 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5721201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737291686194,"sku":"5721201","price":297.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57f349b7c43a4bb3220e198ecb3daba5_3d31c3a2-53ec-45d2-8a6f-4f857a0d4e3a.jpg?v=1788786700","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5721201-end-mill-holder-cat50-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
