Built on the S738R series platform, it features a 1\/4 inch mill diameter, 3\/4 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentration at part corners and extends tool life. The AlTiN PVD coating provides thermal resistance and hardness for dry or semi-dry cutting conditions. With a 38-degree helix angle and close-pitch flute geometry, this tool is engineered to handle both roughing and finishing operations in a single setup. It is installed in standard toolholders with a straight-cylindrical 1\/4 inch shank.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use on CNC machining centers and manual mills where precision corner geometry is required. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material groups P, M, K, and S. The single-end, right-hand cutting and right-hand flute direction make it compatible with conventional CNC spindle configurations. The 2-1\/2 inch overall length provides reach suitable for most standard milling applications without requiring extended-reach toolholding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute close-pitch geometry supports aggressive feed rates in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating delivers oxidation resistance and surface hardness for high-temperature cutting\u003c\/li\u003e\n  \u003cli\u003e0.0300 inch corner radius reduces chipping and part stress at corner transitions\u003c\/li\u003e\n  \u003cli\u003e38-degree medium helix balances chip evacuation with cutting stability\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCapable of both roughing and finishing, reducing tool change frequency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders.

Ensure the machine spindle is fully stopped and locked before mounting or removing the tool from the toolholder. Confirm proper runout before cutting: the maximum TIR for this tool is 0.0005 inches. Follow your facility safety protocols and toolholder manufacturer torque guidelines when securing the shank.\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 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: AlTiN (PVD)\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\u003ePitch\u003c\/strong\u003e: Close\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\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, Titanium\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\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S738R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 17002317\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559392051506,"sku":"17002317","price":116.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b71db816984211a420db58722733575_76e79d44-d3a4-4301-b35c-de23577ee8be.jpg?v=1786431020","url":"https:\/\/voomisupply.com\/products\/seco-17002317-corner-radius-end-mill-1-4in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
