It features a 0.5 inch (1\/2 inch) diameter, a 0.125 inch corner radius, and four flutes with a variable helix and variable index geometry. The PROMAX PowerLayer coating improves wear resistance and heat management across a wide range of workpiece materials. At 4 inches overall length with a 2.25-inch length of cut, this is a long-series tool suited for reaching into deeper pockets and profiles. It is center-cutting and configured for both roughing and finishing passes in a single setup. Machinists and CNC programmers in job shops and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is built for milling steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals. The coarse pitch, variable helix design reduces harmonic chatter during aggressive cuts, making it effective for full-slotting, side milling, and profiling operations. The 0.5 inch straight cylindrical shank mounts directly into standard end mill holders and collet chucks. It is a single-end tool in a long-length configuration, appropriate for setups requiring additional reach without a reduced-shank extension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125 inch corner radius reduces stress concentration and extends tool life at the cutting edge\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003ePROMAX PowerLayer coating for enhanced performance on steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eCapable of roughing and finishing in a single tool  -  no tool change required between operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute direction for use in standard CNC and manual milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill toolholders and collet chucks accepting a 0.5 inch straight cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals (ISO material codes P, M, K, S, N).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and CNC setup technicians using a compatible toolholder or collet chuck. Ensure the machine spindle is fully stopped and the tool is seated to the correct gage length before clamping. Verify runout with a dial indicator after mounting  -  excessive runout accelerates edge wear on carbide tooling. Coolant-through is not supported on this tool; apply flood or mist coolant externally at the cutting zone as required by the workpiece material and operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.125 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: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: PROMAX PowerLayer\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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: No\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 Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0015 to 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: US007\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: US007146\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51989510848818,"sku":"US007146","price":165.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c1bbc8453ecf59bea338f4ba3d77d4c_e8d79821-56e2-4786-bf1a-f3e80df65de9.jpg?v=1789988265","url":"https:\/\/voomisupply.com\/products\/promax-us007146-corner-radius-end-mill-0-5in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
