It features a 3\/4-inch cutting diameter, a 2-inch length of cut, and a 6-inch overall length, making it well-suited for extended-reach profiling and slotting operations. The micrograin carbide construction provides a balance of hardness and toughness. The nACRo finish enhances wear resistance and reduces friction at the cutting edge. Two spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. This tool is installed and used by machinists and CNC operators in job shop, production, and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is applied in vertical and horizontal milling operations on machining centers and CNC mills. The centercutting geometry allows plunge entry directly into a workpiece, expanding its use to pocketing and ramping applications. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle setups. It is appropriate for general-purpose milling of steel, stainless steel, cast iron, and similar materials where a high-helix solid carbide tool is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for extended tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003enACRo coating reduces friction and increases wear resistance at elevated temperatures\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry for pocketing and ramping operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eShank diameter matches cutting diameter at 3\/4 inch for straightforward toolholder setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank solid carbide square end mill compatible with 3\/4-inch collet chucks, end mill holders, and shrink-fit toolholders used on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before loading or unloading the tool. Seat the shank fully into the toolholder to the recommended gauge-line depth and secure per the toolholder manufacturer torque specifications. Inspect the cutting edges for chips or coating damage before each use.\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\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\u003eLength of Cut\u003c\/strong\u003e: 2 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: 6 inches\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\u003eFinish\u003c\/strong\u003e: nACRo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12178857\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748304355634,"sku":"12178857","price":504.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a04859ed73a8d100bdc17a30558bc47.jpg?v=1788892101","url":"https:\/\/voomisupply.com\/products\/accupro-12178857-square-end-mill-3-4-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
