Built from micrograin solid carbide and coated with AlTiN for heat and wear resistance, this tool runs at higher speeds and feeds than standard HSS end mills. It features a 4-flute, right-hand cut configuration with a 40-degree helix angle and an integrated chipbreaker geometry that breaks chips and reduces cutting forces. The square end profile produces flat-bottomed features and shoulders. Shank diameter is 3\/16 inches with a 5\/8-inch length of cut and a 2-inch overall length.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for ferrous and non-ferrous machining applications in CNC milling operations. The AlTiN coating makes it particularly effective in hardened steels, stainless, and cast iron where heat generation is a concern. The chipbreaker design supports heavy roughing passes while the 4-flute geometry allows semi-finish and finish passes without a tool change, making it a practical choice for production machining, tool rooms, and job shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry reduces cutting forces and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge entry\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with straight shank for standard collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 3\/16-inch diameter, 4-flute, straight-shank end mills used in standard CNC machining centers, knee mills, and manual milling machines equipped with compatible collets or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using an appropriate collet, end mill holder, or set-screw adapter matched to the 3\/16-inch shank diameter. Ensure the spindle is fully powered down and locked before tool changes. Torque the retention mechanism to the tool holder specification and verify runout with a dial indicator before cutting. Follow the machine manufacturer and tool manufacturer guidelines for speeds and feeds based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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: Micrograin Solid Carbide\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: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 12184976\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730391204146,"sku":"12184976","price":77.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78fe344df1cd60c5230fc10f5c7d2881.jpg?v=1788716601","url":"https:\/\/voomisupply.com\/products\/accupro-12184976-roughing-end-mill-3-16-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
