Built to a 0.5 inch diameter with a 0.06 inch corner radius, it delivers controlled edge engagement that reduces chipping and extends tool life on hard materials. The 4-flute, right-hand spiral geometry supports both roughing and finishing passes in a single tool, making it a practical choice for machinists and toolroom professionals working across a range of ferrous materials. The 3 inch overall length and 1 inch length of cut suit standard reach applications without sacrificing rigidity.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in steel, stainless steel, superalloys, titanium, and cast iron  -  material groups where submicron carbide grade and corner radius geometry provide a measurable advantage over standard square-end tooling. It is centercutting, allowing plunge entry, and carries a variable index and variable helix to disrupt harmonic chatter in high-speed milling operations. Typical applications include contour milling, pocket profiling, and finishing passes on CNC vertical and horizontal machining centers in job shops, aerospace, and industrial manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grain construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress concentration and extends edge life\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduces chatter in high-speed cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilled pilot holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction, 4-flute spiral configuration supports roughing and finishing\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance fits standard end mill toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill toolholders.

Confirm toolholder bore and collet size match the 0.5 inch shank diameter before mounting. Verify runout after seating the tool, as excessive runout accelerates edge wear and reduces surface finish quality. Follow machine manufacturer torque specifications for drawbar and collet nut tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 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: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FX3\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, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\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: 2100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 310290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51996720038194,"sku":"310290","price":165.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cc0649054787bc4005d2d190b2f5254_0262cf20-cbd8-4b2a-869d-8afb18cd135f.jpg?v=1789993588","url":"https:\/\/voomisupply.com\/products\/gws-310290-corner-radius-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
