Built from micrograin carbide, it delivers consistent cutting performance and edge retention across a wide range of machining applications. The tool features a 7\/16 inch cutting diameter with a 1 inch length of cut, a 4-flute spiral geometry, and a 40-degree helix angle that promotes smooth chip evacuation and reduces cutting forces. At 2-3\/4 inches overall length with a matching 7\/16 inch shank, it mounts directly in standard end mill holders or collet chucks. Machinists and tool-and-die professionals install this end mill on CNC mills and manual knee mills requiring a reliable uncoated general-purpose cutter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in general machining environments. The centercutting design allows direct plunge entry into workpiece material without pre-drilling. Right-hand cut and right-hand flute configuration make it compatible with standard CNC spindle rotation. The uncoated finish works well in applications where coolant is used and where coating buildup or galling is a concern, such as when machining aluminum or other non-ferrous materials. It is a single-end tool intended for production and job-shop use alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for high edge retention and wear resistance\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for coolant-assisted machining of non-ferrous and ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for use with standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style solid carbide square end mill compatible with standard 7\/16 inch end mill holders, ER collet chucks, and milling machine spindles accepting that shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the controller is in a safe state before installing or removing the tool. Seat the shank fully in the holder and torque set screws or collet nuts to the holder manufacturer specification. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.001 \/ -0.000 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\u003eWeight\u003c\/strong\u003e: 0.212 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: 12177086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741404070194,"sku":"12177086","price":95.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5179a8d8e97243e576a61e055a3b7c6.jpg?v=1788831295","url":"https:\/\/voomisupply.com\/products\/accupro-12177086-square-end-mill-7-16-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
