The 3\/4 inch diameter, 2-flute geometry paired with a 45-degree helix angle promotes efficient chip evacuation and smooth cutting action at aggressive feed rates. A ZrN (zirconium nitride) coating extends tool life by improving hardness and lubricity at the cutting edge. The long-length configuration with a 3 inch length of cut (LOC) and 6 inch overall length (OAL) makes this end mill well suited for deep-cavity work where standard-length tools cannot reach. Machinists and toolroom operators working on CNC machining centers and manual mills are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is configured as a single-end, right-hand cut, right-hand spiral tool with no chipbreaker and a standard straight shank at 3\/4 inch diameter. The long reach geometry makes it appropriate for profiling deep pockets, slotting tall workpieces, and contouring operations where extended tool projection is required. The micrograin carbide substrate provides a fine grain structure that supports sharp edge retention under continuous cutting loads in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch milling diameter with a tight tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e3 inch length of cut for deep-pocket and deep-cavity milling applications\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle for aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eZrN coating increases surface hardness and reduces built-up edge on the cutting flutes\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount tooling insert for standard 3\/4 inch ER or side-lock tool holders used on CNC machining centers and manual milling machines accepting straight-shank end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing tooling. Seat the shank fully and evenly into a clean, undamaged collet or end mill holder to the recommended engagement depth per the holder manufacturer. Verify runout at the cutting diameter with a dial indicator before beginning a production cut, as excessive runout accelerates tool wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.75 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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 313477\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728560128306,"sku":"313477","price":412.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5289cb7ed8535869e268e83d9660e477.jpg?v=1788693354","url":"https:\/\/voomisupply.com\/products\/accupro-313477-square-end-mill-3-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
