Built to Series 8470 specifications, it features a 0.5-inch cutting diameter, a 0.0300-inch corner radius, and six flutes with a 43-degree high helix angle. The DUROREY PVD coating provides thermal resistance and surface hardness suited for dry or semi-dry cutting in hardened steels and alloy steels. This is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction, intended for use in CNC machining centers by skilled machinists working in tool and die, mold, and precision component applications.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for finishing passes in hard materials including alloy steel, die steel, and hardened steel. Its close-pitch flute geometry and high helix angle support chip evacuation in tough materials. The straight-cylindrical shank mounts directly into standard collet chucks, end mill holders, and shrink-fit toolholders. It is appropriate for use in vertical and horizontal machining centers where tight surface finish tolerances and corner geometry control are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300-inch corner radius for controlled edge blending and reduced stress concentration at corners\u003c\/li\u003e\n\u003cli\u003eSix-flute close-pitch design supports finishing operations with improved surface finish\u003c\/li\u003e\n\u003cli\u003e43-degree high helix angle aids chip flow in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eDUROREY PVD coating provides wear resistance and thermal stability in hardened steel applications\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability at elevated cutting speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard collet chucks, end mill holders, and shrink-fit toolholders accepting a 0.5-inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before mounting or removing the tool. Verify toolholder runout with a dial indicator before committing to finishing cuts, as runout directly affects surface finish and tool life with six-flute geometries. Follow the toolholder manufacturer torque specifications when tightening collet nuts or set screws.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0 to -0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DUROREY (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8470\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.355 pounds\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: 84702323\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51783608500530,"sku":"84702323","price":320.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94f04b815d3e992b8bb5929917a1e0f5_cef8b984-0b99-465c-b06c-90e57b601187.jpg?v=1789191801","url":"https:\/\/voomisupply.com\/products\/osg-84702323-corner-radius-end-mill-0-5in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
