It features a 1 inch cutting diameter with a 2-flute spiral configuration and a 40-degree helix angle, delivering aggressive chip evacuation and smooth cutting action. The micrograin carbide substrate provides hardness and edge retention at elevated cutting speeds. An nACRo coating reduces friction and heat buildup, extending tool life in demanding materials. This end mill is centercutting, allowing plunge milling entries in addition to standard peripheral and slot milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual mills in job shop, production, and tool-and-die environments. The 2-1\/4 inch length of cut and 5 inch overall length make it well-suited for medium-depth cavities and pocketing operations where reach beyond a standard stub configuration is required. The right-hand cut and right-hand flute configuration is the standard orientation for conventional vertical and horizontal milling setups. It is intended for use by machinists and tooling specialists working in steel, alloy steel, stainless steel, and similar ferrous materials typical for this coating and substrate combination.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness, rigidity, and edge retention\u003c\/li\u003e\n  \u003cli\u003enACRo coating reduces friction and thermal buildup during high-speed cuts\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e2-flute layout maximizes chip clearance in slotting and pocketing applications\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches ensures consistent fit in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and direct-fit tooling option for standard 1 inch straight-shank tool holders, collet chucks, and end mill adapters used on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1 inch shank fully into the holder to the minimum clamping depth required by the holder manufacturer, and torque the retention fastener per the holder specification. Verify runout at the cutting diameter before beginning the cut to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: nACRo\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: 0.25 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: 12178812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748700651826,"sku":"12178812","price":784.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33ecb74d035b1b8f0d3929cdb34f10d5.jpg?v=1788896962","url":"https:\/\/voomisupply.com\/products\/accupro-12178812-square-end-mill-1-inch-2-flutes-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
