It features a 12 mm cutting diameter, a 30 mm length of cut, and a 90 mm overall length. The micrograin carbide substrate paired with a DUROREY coating delivers wear resistance and thermal stability at elevated cutting speeds. A 43-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This tool is intended for use by machinists and CNC operators working in job shop, production, or tool room environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits vertical and horizontal milling operations requiring tight tolerances and clean square shoulders. It is well matched to finishing and semi-finishing passes in steel, stainless steel, cast iron, and similar materials where coating performance is critical. The single-end, right-hand cut and right-hand flute configuration is standard for conventional CNC milling center setups. The 12 mm shank diameter matches the cutting diameter for direct collet or end mill holder installation without a reducer sleeve.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6 flutes for improved surface finish and feed rate capability\u003c\/li\u003e\n\u003cli\u003eDUROREY coating for enhanced wear resistance and heat management\u003c\/li\u003e\n\u003cli\u003e43-degree helix angle promotes effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 12 mm shank in ER collets, end mill holders, or hydraulic chucks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank to the recommended gauge line depth in the holder and torque the retention mechanism to the holder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 90 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: DUROREY\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.7 inches L x 0.75 inches H x 0.65 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8549812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753456107826,"sku":"8549812","price":260.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46a3254f5acde6e640620cad36430345_729de210-f2db-4c2a-8997-a3802dc279c6.jpg?v=1788936987","url":"https:\/\/voomisupply.com\/products\/osg-8549812-square-end-mill-12mm-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
