Built from micrograin carbide and finished with an AlTiN coating, this tool delivers wear resistance and thermal stability across a range of workpiece materials including hardened steels, stainless, and cast iron. The 4-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and stable cutting action. Centercutting capability allows for direct plunge entry without pre-drilling. At 4 inches overall length, this end mill falls into the extra-long category, giving machinists reach for deep-pocket and extended-reach operations where standard-length tooling falls short.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual mills in job shop, production, and toolroom environments. The extra-long overall length and 1.375-inch length of cut make it well suited for milling deep pockets, slots, and contoured features in ferrous and non-ferrous materials. Right-hand cut and right-hand flute orientation follow standard spindle conventions, making setup straightforward. The AlTiN finish extends tool life when cutting dry or with minimal lubrication at elevated cutting speeds. Machinists working in aerospace, mold-and-die, and general metalworking will find this geometry a practical fit for multi-pass profiling and slotting operations requiring extended reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish provides thermal and oxidation resistance for dry and high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtra-long 4-inch OAL with 1.375-inch length of cut for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual mill spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit tooling solution for standard 7\/16-inch collets, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills requiring a 7\/16-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and power is locked out before inserting or removing the tool from the holder. Verify collet or holder bore size matches the 7\/16-inch shank before clamping; observe the shank diameter tolerance specification to confirm proper grip. Do not exceed the holder's clamping torque range as specified by the toolholder manufacturer, and inspect the cutting edges for chipping before each use.\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\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.3750 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\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\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: 12183416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747591192882,"sku":"12183416","price":122.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ab3aa8ffbd5122e43ac851032885405.jpg?v=1788883056","url":"https:\/\/voomisupply.com\/products\/accupro-12183416-square-end-mill-7-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
