It features a 3\/4 inch cutting diameter, a 1-5\/8 inch length of cut, and a 4 inch overall length with a 3\/4 inch shank diameter. The tool is constructed from micrograin solid carbide and coated with AlTiN (Aluminum Titanium Nitride) for extended tool life at elevated cutting temperatures. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. This end mill is centercutting, allowing plunge milling in addition to peripheral and slot milling. It is installed and used by machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for high-speed milling of ferrous metals, hardened steels, cast iron, and similar alloys in both conventional and climb milling applications. The right-hand cut and right-hand flute configuration is standard for use in conventional vertical and horizontal machining centers. The AlTiN coating provides heat resistance that extends tool life in dry or minimal-lubrication cutting conditions. It is appropriate for both roughing and finishing passes within its length-of-cut range of 1.5 to 2.0 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling capability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC machining center use\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank replacement end mill for CNC vertical machining centers and manual mills accepting a 3\/4 inch straight shank tool holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by machinists using an appropriate 3\/4 inch collet chuck or end mill holder on a CNC or manual milling machine. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Verify shank seating depth and runout with a dial indicator before initiating a cut. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting feeds, speeds, and depth of cut.\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: 1-5\/8 inch (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.5 to 2.0 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\u003eOverall Length\u003c\/strong\u003e: 4.0 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\u003eCoating\u003c\/strong\u003e: AlTiN\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: 12180469\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744572277042,"sku":"12180469","price":361.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f898e07cd3346d6e50f9e35818492b84.jpg?v=1788858411","url":"https:\/\/voomisupply.com\/products\/accupro-12180469-square-end-mill-3-4-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
