Built with 7 flutes and a 0.03 inch corner radius, it reduces edge chipping and improves surface finish on contoured profiles. The AlTiN coating provides high heat resistance and extended tool life in demanding cutting environments. With a 0.5 inch mill diameter, a 1-5\/8 inch length of cut, and a 4 inch overall length, this single-end centercutting tool suits plunge, slot, and profile milling applications. It is installed and operated by machinists and CNC programmers working in job shops, aerospace, and precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for high-speed machining of steel, stainless steel, cast iron, and other hard materials where corner integrity and tool longevity are priorities. The 7-flute geometry increases feed rates compared to standard 4- or 5-flute tools, making it effective for semi-finish and finish passes. The variable index design reduces harmonic vibration during cut, improving dimensional accuracy. The 0.5 inch shank diameter fits standard ER and side-lock tool holders used on vertical machining centers and CNC mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03 inch corner radius reduces stress concentration and extends tool life on profiled cuts\u003c\/li\u003e\n  \u003cli\u003e7-flute design supports higher feed rates for semi-finish and finish milling\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating delivers high-temperature hardness and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with right-hand spiral flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC vertical machining centers and manual mills accepting a 0.5 inch shank diameter in standard ER collet chucks, milling chucks, or side-lock holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout\/tagout state before changing tooling. Seat the shank to the minimum insertion depth recommended by the tool holder manufacturer and torque the collet nut or set screw per the holder specification. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 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 Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 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: 12178719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738643956018,"sku":"12178719","price":164.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35ec04fe2a6ce53674298bb4bdea950b.jpg?v=1788802255","url":"https:\/\/voomisupply.com\/products\/accupro-12178719-corner-radius-end-mill-1-2-in-7-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
