It features a 3\/8 inch diameter, a 1 inch length of cut, and a 0.045 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The AlTiN (Ti-NAMITE-A) coating provides high heat resistance and hardness, making this tool well-suited for high-speed cutting in tough materials. With 4 flutes and a right-hand spiral flute design, it delivers efficient chip evacuation and a quality surface finish. This end mill is a single-end, Weldon flat shank tool with a 2.5 inch overall length and is used in standard end mill toolholders. Machinists and tool-and-die professionals install and operate this tool on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing and finishing operations across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is also rated for secondary use in hard materials. The corner radius geometry makes it particularly effective in applications where sharp inside corners are not required and where edge chipping is a concern, such as profiling, slotting, and peripheral milling in production or job-shop environments. The micrograin carbide substrate and medium helix combine to provide stability at elevated cutting parameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch diameter with 0.045 inch corner radius for reduced edge stress and longer tool life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating (Ti-NAMITE-A designation) for high heat and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design supports both roughing and finishing operations\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for positive retention in standard end mill toolholders\u003c\/li\u003e\n\u003cli\u003eVariable index geometry reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill toolholders.

Confirm the Weldon flat shank is fully seated and the setscrew engages the flat before operation. Verify spindle RPM and feed rate are set per the applicable cutting data for the workpiece material before starting the cut. Never exceed the tool's rated cutting diameter or depth of cut without confirming rigidity of the setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\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, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 01C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38173\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51737581617458,"sku":"38173","price":98.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9616317ef44793bd5a097a0bcd5fd89.jpg?v=1788790811","url":"https:\/\/voomisupply.com\/products\/sgs-38173-corner-radius-end-mill-3-8-in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
