It features a 1\/2 inch diameter, a 1-1\/4 inch length of cut, and a 0.0300 inch corner radius that reduces edge chipping and improves surface finish in hardened or abrasive workpieces. The AlCrN PVD coating provides heat and oxidation resistance, extending tool life at elevated cutting temperatures. At 3 inches overall length with a 1\/2 inch Weldon flat shank, this end mill mounts securely in standard toolholders and is suited for both roughing and finishing operations on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for machinists and toolroom professionals working on CNC mills and machining centers where tight tolerances and tool life in hard materials are critical. The STR440 series targets applications in aerospace, medical, and precision manufacturing where stainless steel, superalloys such as Inconel, and titanium alloys are common workpiece materials. The single-end, centercutting design allows plunge entry and full slot milling. The 40-degree high helix angle promotes chip evacuation and reduces cutting forces in tough materials, making it well suited for both side milling and light plunge cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlCrN PVD coating enhances oxidation resistance and extends tool life in high-heat applications\u003c\/li\u003e\n  \u003cli\u003e0.0300 inch corner radius reduces stress concentration and chipping at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes efficient chip evacuation and lower cutting forces\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive engagement and reduced pullout risk in toolholders\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing operations in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 1\/2 inch Weldon flat shank.

Ensure the machine spindle is fully stopped and the tool change procedure follows the machine manufacturer's guidelines before mounting or removing the end mill. Seat the Weldon flat shank fully into the toolholder and tighten the set screw against the flat to prevent axial pullout during cutting. Verify runout does not exceed the specified TIR maximum of 0.0005 inch after mounting before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 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\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eCentercutting\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: Stainless Steel, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 \/ +0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STR440\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17004141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561604612402,"sku":"17004141","price":164.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dda6c280e6940becca290de00d3efb0d.jpg?v=1786466369","url":"https:\/\/voomisupply.com\/products\/seco-17004141-corner-radius-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
