It features a 1\/4 inch diameter, a 0.01 inch corner radius, and four flutes arranged in a variable index, variable helix configuration that reduces harmonic vibration and improves surface finish. The 3\/8 inch length of cut and 2 inch overall length make this a short-series tool suited to rigid setups. It is center-cutting and right-hand cutting, with a straight cylindrical shank at 1\/4 inch diameter holding to h6 tolerance. Installation is performed by machinists and CNC tooling technicians running milling centers and machining cells.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for roughing and finishing operations on steel, stainless steel, superalloys, and titanium as primary workpiece materials, with cast iron as a secondary application. The submicron carbide grade and variable helix geometry make it well suited to high-speed machining of difficult-to-cut alloys. The spiral flute configuration promotes efficient chip evacuation in these materials. It accepts standard end mill toolholders with a 1\/4 inch straight bore. No coolant-through capability is present, so external coolant or air blast is recommended when running at elevated feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius reduces stress concentration and extends tool life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eVariable index and variable helix flute geometry dampens vibration for improved finish and tool stability\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunging into the workpiece without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral with normal pitch for conventional and climb milling\u003c\/li\u003e\n  \u003cli\u003eh6 shank tolerance ensures accurate, repeatable seating in precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard end mill toolholders accepting a 1\/4 inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the end mill. Torque the set screw or collet to the toolholder manufacturer specification. Verify runout at the cutting edge before beginning a production run, as excessive runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\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: 3\/8 inch (0.2550 inch \/ 9.52 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 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 Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (FX3 finish)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eFor Use With\u003c\/strong\u003e: End Mill Toolholders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.96 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: 310078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51978448798002,"sku":"310078","price":71.09,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cc0649054787bc4005d2d190b2f5254_5335065d-ef27-4cde-9a1f-c53221289774.jpg?v=1789980169","url":"https:\/\/voomisupply.com\/products\/gws-310078-corner-radius-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
