It features a 12 mm cutting diameter, a 38 mm length of cut, and a 0.5 mm corner radius that reduces stress concentration at the cutting edge and extends tool life in interrupted cuts. The variable helix geometry helps break up harmonic chatter, making it effective in both roughing and finishing passes. Applied with a Duarise PVD coating, this end mill is built for high-performance cutting in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is installed in CNC machining centers using a standard straight-cylindrical shank toolholder.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for shops running precision milling on a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The long-length configuration supports deeper axial reach in pockets, slots, and profiling applications. The center-cutting design allows for direct plunge entry. With right-hand flute direction and right-hand cutting direction, it is compatible with standard CNC spindle setups. The single-end configuration keeps the tool compact in tight-clearance fixturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 mm cutting diameter with 0.5 mm corner radius for reduced edge chipping and improved surface finish\u003c\/li\u003e\n\u003cli\u003eVariable helix design dampens vibration and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eDuarise PVD coating provides heat and wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e4-flute helical geometry supports both roughing and finishing material removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for direct plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003eLong-length flute (38 mm LOC) for deep pocket and profile work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical shank toolholders in CNC milling machines.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting. Verify runout with a dial indicator after seating the tool in the holder to confirm proper alignment. Follow the toolholder manufacturer torque specifications for the collet or set screw used with 12 mm straight-cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 38 mm (1.4961 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.03 to -0.03 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.00 to -0.02 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Duarise (PVD)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8277\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.39 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.05 inches L x 0.75 inches H x 0.65 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8556350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754969628978,"sku":"8556350","price":319.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d47c0661037dabab158627b9330a6afb_187bf0c9-4cb8-4fb6-a35d-4003f50898f7.jpg?v=1788950264","url":"https:\/\/voomisupply.com\/products\/osg-8556350-corner-radius-end-mill-12mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
