Built from micrograin carbide and coated with AlCrTiN for heat and wear resistance, this tool delivers extended tool life in hardened steels, stainless, and high-temperature alloys. It runs a 7-flute, right-hand spiral configuration with a 38-degree helix angle, offering improved chip evacuation and surface finish in deep-cavity and long-reach applications. The 0.060-inch corner radius reduces stress concentration at the cutting edge, minimizing chipping in aggressive passes. Installed by machinists and toolroom technicians on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing and semi-finishing operations where extended reach is required. The 3.250-inch length of cut and 6.000-inch overall length make it appropriate for deep-pocket milling and tall-wall part features. The straight cylindrical shank at 1\/2 inch diameter fits standard ER and end mill holders. Non-centercutting geometry means this tool is intended for side milling and ramping entry strategies rather than direct plunge cuts. Applicable in aerospace, die-mold, and general precision machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating provides high-temperature hardness and oxidation resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003e7-flute design increases feed rates and improves surface finish compared to standard 4-flute configurations\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers superior rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e0.060-inch corner radius reduces edge chipping and stress concentration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes efficient chip flow and reduces cutting forces in deep pockets\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting construction — requires side entry, ramping, or helical interpolation for pocket entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-purpose tooling option for CNC machining centers and manual mills accepting a 1\/2-inch straight cylindrical shank end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with CNC tooling setup. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before loading or unloading tooling. Verify holder runout with a dial indicator before committing to a production setup, as excessive runout will accelerate edge wear on a 7-flute geometry. Because this tool is non-centercutting, program entry moves as a ramp or helical interpolation — never a straight Z-axis plunge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 3-1\/4 inches (3.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSeries\u003c\/strong\u003e: HS\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312662\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51752562884914,"sku":"312662","price":295.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7560ccda74557ed8fa3056dcdc0f777.jpg?v=1788929116","url":"https:\/\/voomisupply.com\/products\/accupro-312662-corner-radius-end-mill-1-2-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
