Part of the SGS Series 55MS, this stub-length end mill features a 0.3937 inch cutting diameter, a 0.6299 inch length of cut, and five flutes with a 45-degree helix angle for aggressive chip evacuation and surface finish quality. The variable index geometry reduces harmonic vibration during high-speed cutting passes. An AlTiN coating provides thermal resistance and extended tool life when cutting ferrous and exotic alloys. This tool is intended for use by machinists, tool-and-die professionals, and CNC machine operators working in production or job shop environments.\u003c\/p\u003e\n\u003cp\u003eThe SGS 42612 is suited for milling hardened steels, stainless steels, titanium, high-temperature alloys, and cast irons, corresponding to material code groups H, K, M, P, and S. The straight cylindrical shank measures 0.3937 inches in diameter with a shank diameter tolerance of +0.000 to -0.009 mm, ensuring reliable collet or end mill holder retention. The stub length profile adds rigidity and reduces deflection in applications requiring tight tolerances or higher radial engagement depths.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for hardness and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature oxidation resistance and reduced friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing minimizes chatter and harmonic vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral geometry for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with ER collet chucks, end mill holders, or hydraulic toolholders accepting a 0.3937 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the shank to the full recommended insertion depth in the holder and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine OEM guidelines for appropriate speeds, feeds, and depth of cut for the target workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6299 inches (16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.050 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.009 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 55MS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 42612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731738493234,"sku":"42612","price":87.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9106fc41acbc17a8ec2f83c17631f166_2072f46b-b0a7-4c70-bf52-2b0d4ce9e3aa.jpg?v=1788734394","url":"https:\/\/voomisupply.com\/products\/sgs-42612-square-end-mill-0-3937-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
