Built on the STR440.2 series platform, this 4-flute tool features a 1\/4 inch diameter, a 1\/2 inch length of cut, and a 40-degree variable helix geometry that helps reduce chatter and improve chip evacuation. The HTA PVD coating provides elevated wear resistance for extended tool life in difficult-to-machine materials. Right-hand cutting direction with a straight-cylindrical shank and centercutting capability make it suitable for plunge entry and complex milling paths.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where precise corner radii and surface finish quality are required. It is rated for use on stainless steels and superalloys, aligning with material codes M and S classifications. Typical install environments include production shops, job shops, and toolroom applications where a compact short-length end mill is needed for high-accuracy work on challenging workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eHTA PVD coating for extended tool life on stainless and superalloy workpieces\u003c\/li\u003e\n\u003cli\u003eVariable helix geometry reduces vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003e0.0625 inch corner radius for controlled edge blending and reduced stress concentrations\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003e4-flute configuration supports both roughing and finishing material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification tool within the SECO STR440.2 series, suited for 1\/4 inch collet or end mill holders in CNC and manual milling applications on stainless steel and superalloy workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a properly sized collet or end mill holder rated for 1\/4 inch shank diameter and verify runout does not exceed the 0.0005 inch TIR maximum specification before beginning a cut. Do not exceed the recommended length of cut or depth of cut beyond the tool geometry without verifying rigidity and setup stability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0625 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 (variable)\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: HTA (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\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 (M), Superalloys (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STR440.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10115924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558182551858,"sku":"10115924","price":92.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52f4788599c70ccfa660ccede1a9fc2c.jpg?v=1786405569","url":"https:\/\/voomisupply.com\/products\/seco-10115924-corner-radius-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
