With a 7\/16 inch (0.4375 inch) cutting diameter and a 3-inch length of cut, this tool handles deep-reach profiling, slotting, and peripheral milling in a single setup. The micrograin carbide substrate paired with an AlTiN finish provides heat resistance and edge retention at elevated cutting speeds. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. At 6 inches overall length, this is an extra-long configuration suited for setups requiring extended reach without sacrificing rigidity. It is installed by machinists and CNC operators working in job shops, tool rooms, and production machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is well-suited for milling steel, stainless steel, cast iron, and other ferrous materials where the AlTiN coating delivers thermal protection. The extra-long 6-inch OAL makes it appropriate for deep cavity work, tall workpiece features, and applications where standard-length tools cannot reach. It fits standard collet chucks, end mill holders, and shrink-fit toolholders with a 7\/16 inch bore. The 3-flute geometry balances chip volume and rigidity, making it a practical choice for both roughing and finishing passes on difficult materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN finish for high-temperature resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin carbide substrate for improved hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch OAL provides reach for deep cavity and tall-feature milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute configuration for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for any setup requiring a 7\/16 inch shank end mill in a collet chuck, end mill holder, or shrink-fit toolholder with 7\/16 inch bore capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before loading or changing tooling. Verify the holder bore matches the 7\/16 inch shank diameter and apply appropriate tightening torque per the toolholder manufacturer's specification. Confirm runout with a dial indicator after seating to minimize premature tool wear and maintain dimensional accuracy.\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 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eFinish \/ Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (0.4375 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra 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\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: 12182252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729301012786,"sku":"12182252","price":138.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3cbc924ff868019a9e4f37a599bb75f7.jpg?v=1788702626","url":"https:\/\/voomisupply.com\/products\/accupro-12182252-square-end-mill-7-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
