It features a 3\/16 inch cutting diameter, five flutes, and an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life at elevated cutting speeds. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This end mill is single-end, center-cutting, and manufactured from micrograin carbide for consistent edge integrity. It is installed by machinists and CNC operators working in job shops, production facilities, and tool rooms.\u003c\/p\u003e\u003cp\u003eThis end mill suits finishing and semi-finishing operations on hardened steels, stainless steels, cast iron, and similar ferrous materials. The AlTiN finish performs well in dry or minimal-lubrication cutting environments where heat buildup is a concern. With a 3\/8 inch length of cut and 2 inch overall length, it fits standard toolholders and collet chucks in vertical machining centers and manual milling machines. The right-hand cut and right-hand spiral flute configuration is the standard orientation for conventional CNC milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in ferrous and high-temp alloy cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes chip flow and reduces cutting pressure\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry as well as peripheral milling\u003c\/li\u003e\n\u003cli\u003eFive-flute geometry increases feed rate capability versus four-flute tools\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit solid carbide end mill for standard 3\/16 inch collet chucks, end mill holders, and shrink-fit toolholders used in CNC vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Insert the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\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: 12180716\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738218299698,"sku":"12180716","price":41.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e7ba45777800b633e7ee61521db0ed9.jpg?v=1788796895","url":"https:\/\/voomisupply.com\/products\/accupro-12180716-square-end-mill-3-16-inch-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
