It features a 7\/16 inch cutting diameter, a 1 inch length of cut, and a 4 inch overall length, making it a long-reach option suited for deeper pocket and slot milling. The 2-flute geometry and 40-degree helix angle promote efficient chip evacuation in a range of ferrous and non-ferrous materials. An AlTiN coating adds heat resistance and surface hardness, extending tool life in high-speed and dry-cutting applications. Micrograin carbide construction provides the edge retention and rigidity needed for demanding cuts. This tool is installed and used by machinists and CNC operators in job shops, toolrooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 7\/16 inch collets and tool holders. It is well suited for slot milling, profiling, and peripheral milling on CNC machining centers and manual mills. The centercutting design allows direct plunge entry into the workpiece. Right-hand cut and right-hand flute orientation follow conventional milling norms. The long flute length relative to diameter makes it practical for applications requiring deeper cuts without a tool change.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for high rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in dry or high-speed cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC and manual mill setups\u003c\/li\u003e\n\u003cli\u003eLong length type with 1 inch LOC provides reach for deeper pockets and slots\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 7\/16 inch collets and end mill holders on CNC machining centers and manual milling machines requiring a 2-flute solid carbide square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in a clean, undamaged collet or tool holder and torque the retention nut to the holder manufacturer specification. Inspect the cutting edges and coating for chips or wear before each use; do not run a damaged end mill at speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2\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: 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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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\u003eVariable Helix\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\u003eWeight\u003c\/strong\u003e: 0.3 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: 12181820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731158139186,"sku":"12181820","price":108.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b146b26891ac9ee702aff5c486a2b2f4_4bb68f50-c831-4f15-9fc3-a12f2dc02123.jpg?v=1788727720","url":"https:\/\/voomisupply.com\/products\/accupro-12181820-square-end-mill-7-16-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
