It features a 3\/8 inch diameter with a 1-1\/4 inch length of cut and a 3 inch overall length. The 7-flute geometry combined with an AlCrTiN coating delivers high heat resistance and extended tool life in abrasive and hard materials. The 38-degree right-hand spiral helix promotes efficient chip evacuation while maintaining surface finish quality. This is a non-centercutting, single-end tool with a straight cylindrical shank, intended for use by machinists and tool-and-die professionals in CNC and manual milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for side milling, profiling, and contouring operations in ferrous and non-ferrous materials where a small corner radius blend is required at the base of a cut. The 0.060 inch corner radius reduces stress concentration at the cutting edge and extends tool life compared to sharp-corner tooling. It is appropriate for finish and semi-finish passes in production environments where tight tolerances and consistent edge geometry are required. The micrograin carbide substrate supports use in high-speed and high-feed applications common in aerospace, mold, and die machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute design increases feed rates and improves surface finish in finishing operations\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating provides high-temperature oxidation resistance for hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e0.060 inch corner radius reduces chipping at the cutting edge and improves part geometry at floor-wall intersections\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, non-centercutting single-end configuration for profiling and peripheral milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill for CNC machining centers and manual mills accepting a 3\/8 inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist using an appropriate collet or end mill holder rated for the 3\/8 inch shank diameter. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before mounting. Verify runout after installation, as excessive runout on a 7-flute tool will accelerate uneven wear. This is a non-centercutting tool and must not be used for plunge cuts directly into solid material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 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: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312599\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749493932338,"sku":"312599","price":111.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b1b94845bcff2067ed67561c86dac70.jpg?v=1788906804","url":"https:\/\/voomisupply.com\/products\/accupro-312599-corner-radius-end-mill-3-8-in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
