It carries a 3\/8 inch cutting diameter, a 0.015 inch corner radius, and seven flutes arranged in a right-hand spiral with a 38-degree helix angle. The AlTiN PVD coating improves heat resistance and extends tool life when cutting abrasive or tough materials at elevated speeds. At 2.5 inches overall length with a 0.5 inch length of cut, this stub-length geometry provides rigidity and reduces deflection in tight-tolerance finishing and roughing passes. Machinists and CNC setup technicians working in job shops, production facilities, or tool rooms are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for single-end milling operations in steel, stainless steel, cast iron, superalloys, and titanium. The close pitch and micrograin carbide substrate support both roughing and finishing passes without a tool change. The 7-flute configuration increases chip load per tooth at higher feed rates, making it effective for semi-finishing and finishing operations where surface finish consistency matters. It is used in vertical and horizontal machining centers with straight-cylindrical toolholders. The S738R series designation identifies the geometry family within the SECO product line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for cutting steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e7-flute close-pitch design supports higher feed rates in roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and improves corner strength on milled profiles\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle with right-hand cut and right-hand flute direction for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStub-length geometry maximizes rigidity and minimizes deflection in short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with straight-cylindrical toolholders accepting a 3\/8 inch shank diameter.

Confirm toolholder bore diameter matches the 3\/8 inch shank before mounting and verify runout against the stated TIR maximum of 0.0005 inch after clamping. Do not exceed toolholder torque specifications provided by the toolholder manufacturer. Coolant-through is not supported by this tool; external coolant or air blast is required for chip management.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.001 to -0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.002 \/ 0.000 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: -0.06 \/ +0.06 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: 0.14 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: 17002322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560932311346,"sku":"17002322","price":132.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7b3d388458dd9e311df51dda5d3dc92.jpg?v=1786459585","url":"https:\/\/voomisupply.com\/products\/seco-17002322-corner-radius-end-mill-3-8-in-7-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
