It features a 12 mm cutting diameter, a 2.50 mm (0.0984 inch) corner radius, and four helical flutes with a variable helix and variable index geometry. The TX coating enhances surface hardness and heat resistance for extended tool life at elevated cutting speeds. At 83 mm overall length with a 26 mm length of cut, this single-end tool suits both roughing and finishing operations in production machining environments. Licensed machinists and CNC operators working in job shops or manufacturing cells are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for cutting steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material codes P, M, K, and S as primary workpiece materials, with hard materials (code H) as a secondary application. The extended reach design, with a 35.99 mm reach length and 11.48 mm neck diameter, allows access to deeper cavities and stepped features without sacrificing rigidity. The Weldon flat shank is sized at 12 mm to seat securely in standard end mill holders, making it compatible with common CNC machining center tooling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and thermal resistance in hard-material applications\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduces harmonic vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e2.50 mm corner radius (0.0984 inch) protects corners from chipping and improves surface finish at part radii\u003c\/li\u003e\n  \u003cli\u003eTX coating for increased wear resistance on steel, stainless steel, and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 35.99 mm reach length and reduced neck diameter for deep-cavity access\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank ensures positive retention in end mill holders during high-torque cuts\u003c\/li\u003e\n  \u003cli\u003eSuitable for both roughing and finishing in a single tool, reducing changeover time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before loading or unloading the tool. Seat the Weldon flat shank fully into the holder and torque the set screw to the holder manufacturer specification before engaging a cut. Verify runout at the tool tip with a dial indicator after setup to confirm proper seating and avoid premature edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 26 mm (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 83 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 11.48 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 35.99 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0500 to 0.0000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0508 to 0.0000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ZPMC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: End Mill Holders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.267 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.27 inches length x 0.71 inches width x 0.71 inches height\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: 42731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51744468042034,"sku":"42731","price":186.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c34c2685827a7b14d1c130d2db0c77e_8f1543cf-b7f4-4226-b47d-a703feb333b6.jpg?v=1788856921","url":"https:\/\/voomisupply.com\/products\/sgs-42731-corner-radius-end-mill-12mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
