With a 7\/16 inch (0.4375 inch) cutting diameter and a 1 inch length of cut, this two-flute tool delivers clean, accurate slots, pockets, and profiling passes. The TiCN (titanium carbonitride) coating increases surface hardness and reduces tool wear, extending service life in harder workpiece materials. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin solid carbide construction provides rigidity and edge retention that high-speed steel tooling cannot match. This is a right-hand cut, right-hand flute configuration with a spiral flute geometry.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills performing general-purpose milling on steel, stainless, cast iron, and similar materials. The centercutting design allows plunge entry directly into the workpiece without pre-drilling. With a 7\/16 inch shank diameter and 2-3\/4 inch overall length, it fits standard ER and side-lock toolholders common in production and job shop environments. The regular length classification makes it appropriate for standard-reach applications where a stub or long-reach tool is not required. Machinists, tool-and-die makers, and CNC operators in manufacturing and maintenance environments are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for superior rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for increased hardness and extended tool life on harder materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 7\/16 inch shank square end mill compatible with ER collet chucks, side-lock holders, and shrink-fit toolholders accepting a 7\/16 inch shank diameter.

Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before loading or removing the tool. Seat the shank to the minimum insertion depth recommended for the toolholder type in use to maintain runout accuracy. Verify spindle speed and feed rate against published cutting data for the workpiece material and coating type before starting the cut.\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\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\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\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\u003eCoating\u003c\/strong\u003e: TiCN\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: Regular\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\u003eExtended Reach\u003c\/strong\u003e: No\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: 12181444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748266180914,"sku":"12181444","price":71.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9593e97e6456c49db2e57ccfbf9592f.jpg?v=1788891416","url":"https:\/\/voomisupply.com\/products\/accupro-12181444-square-end-mill-7-16-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
