Built to the T12-201 series Tuffy material grade specification, this two-flute tool features a 5\/8-inch cutting diameter, a 7\/8-inch length of cut, and a 3-1\/4-inch overall length. The stub-length configuration provides added rigidity during aggressive cuts. A 30-degree helix angle and spiral flute geometry promote efficient chip evacuation. This end mill is uncoated and ships ready for use on manual mills and CNC machining centers. It is installed and operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling applications in ferrous and non-ferrous materials. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled hole. Right-hand cut and right-hand flute orientation make it compatible with standard spindle rotation on vertical and horizontal milling machines. The stub length is particularly effective in setups where tool overhang must be minimized to maintain tolerances and reduce deflection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide Tuffy material grade construction for wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral design promotes chip clearance in slot and pocket milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting forces and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eStub length body reduces deflection in tight-clearance or short-reach setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling solution for standard straight-shank collet chucks and end mill holders accepting a 5\/8-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis end mill is installed by qualified machinists familiar with milling machine operation and toolholder setup. Secure the shank fully into the collet or end mill holder to the minimum recommended engagement depth before tightening. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after seating to confirm concentricity within acceptable limits for the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Tuffy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 \/ -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T12-201\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: ROBBJACK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T12-201-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":51972448158002,"sku":"T12-201-20","price":376.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/16a9869ed7d5949a5aabceeb772d0d48_97fae2ae-4efc-4b6f-9a2b-c6b0051a956a.jpg?v=1789969184","url":"https:\/\/voomisupply.com\/products\/robbjack-t12-201-20-square-end-mill-5-8-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
