It carries a 0.0300-inch corner radius, a 3\/4-inch cutting diameter, and a 2-1\/4-inch length of cut. The micrograin carbide substrate is coated with AlTiN via a PVD process, providing thermal resistance and extended tool life in abrasive materials. A 38-degree helix angle and super-close pitch geometry support both roughing and finishing operations in a single tool. This end mill is a single-end, right-hand cut, right-hand flute design intended for use with standard straight-cylindrical toolholders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, superalloys, and titanium — material application codes P, M, K, and S. The S938R series targets shops running high-feed or high-speed strategies on difficult-to-machine alloys where tool life and surface finish consistency are critical. It fits production and job-shop environments running CNC vertical or horizontal machining centers. The single-end design is standard for indexing toolpaths where full length of cut engagement is required across deep-wall or shoulder features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for high-temperature oxidation resistance in dry or near-dry cutting\u003c\/li\u003e\n  \u003cli\u003e9 flutes with super-close pitch for improved surface finish and chip load distribution\u003c\/li\u003e\n  \u003cli\u003e0.0300-inch corner radius reduces stress concentration and extends tool life at cutting edges\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle supports smooth chip evacuation in deep-slot and shoulder applications\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing — reduces tool changes in multi-operation setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 3\/4-inch shank diameter.

Ensure the toolholder bore and retention mechanism are clean and free of chips before inserting the shank. Confirm runout does not exceed the 0.0005-inch TIR maximum specification after seating to avoid premature edge wear. Do not use this end mill in centercutting operations — this tool is not centercutting and is not designed for plunge entry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 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\u003eNumber of Flutes\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (5.0000 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\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 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\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\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: Super 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\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\u003eSeries\u003c\/strong\u003e: S938R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 17002363\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563588649266,"sku":"17002363","price":674.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0031b782cd23a96992b001cda061341_d5e8af53-517a-473b-b4f5-4e21d48e7b50.jpg?v=1786499506","url":"https:\/\/voomisupply.com\/products\/seco-17002363-corner-radius-end-mill-3-4-in-9-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
