It features a 3\/4 inch cutting diameter, a 2-1\/4 inch length of cut, and a 5 inch overall length, making it well-suited for both slotting and peripheral milling. The nACRo finish provides enhanced wear resistance and heat reduction at the cutting edge. With a 40-degree helix angle and spiral flute geometry, this tool evacuates chips efficiently and maintains stable cutting action. It is a centercutting design, allowing plunge entry into the workpiece. The micrograin carbide substrate contributes to edge retention in demanding materials.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual milling machines for cutting ferrous and non-ferrous metals. It is a single-end, right-hand cut, right-hand flute tool with a 3\/4 inch shank diameter that fits standard ER collet chucks, side-lock holders, and shrink-fit toolholders. Typical applications include profiling, contouring, slotting, and pocketing operations in job shops, production machining, and toolroom environments. Machinists and CNC operators select this geometry when working with steel, stainless, or high-temperature alloys where a longer length of cut is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003enACRo coating reduces friction and extends tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches ensures consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or new installation for standard 3\/4 inch shank toolholders used in CNC machining centers and manual knee mills requiring a 2-flute square end mill with a 3\/4 inch cutting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is secure in a properly sized collet or toolholder before operation. Verify runout after installation to maintain dimensional accuracy and extend tool life. Follow the machine tool manufacturer and tooling manufacturer guidelines for feeds, speeds, and depth of cut appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: nACRo\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\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: 0.5 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: 12178822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744620118322,"sku":"12178822","price":403.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa671b2b9414d9bacd0bbe0999539093_8e77a858-a2a8-4f5b-9441-f17994adeb49.jpg?v=1788859090","url":"https:\/\/voomisupply.com\/products\/accupro-12178822-square-end-mill-3-4-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
