It features an AlTiN coating and a 40-degree helix angle, which together improve chip evacuation and extend tool life in ferrous and high-temperature alloy applications. The 3\/16 inch cutting diameter and 3\/4 inch length of cut make it well suited for slot milling, profiling, and contouring in tight-tolerance work. Machining centers and CNC mills running demanding materials benefit from the chipbreaker geometry, which reduces cutting forces and controls chip size during aggressive passes.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision machining shops, tool rooms, and production environments where a single tool must handle both material removal and finish passes. The long-length configuration at 2-1\/2 inches overall length provides additional reach for deeper pockets and stepped features. Right-hand cut and right-hand flute direction are standard for conventional CNC and manual milling setups. It is a single-end tool with a 3\/16 inch straight shank for direct collet or end mill holder mounting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in dry or minimal-lubrication cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting pressure\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry enables aggressive roughing passes while controlling chip size\u003c\/li\u003e\n\u003cli\u003eCombined roughing and finishing capability reduces tool changes and setup time\u003c\/li\u003e\n\u003cli\u003eLong-length OAL of 2-1\/2 inches provides reach for deeper features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition for CNC machining centers and manual mills using 3\/16 inch collets or end mill holders with right-hand rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The tool must be seated fully in a clean, undamaged collet or end mill holder and torqued to the holder manufacturer's specification before use. Inspect the shank and cutting edges for chips or damage before each use. Ensure spindle speed and feed rate are set according to the material being cut and the manufacturer's recommended parameters for carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Type\u003c\/strong\u003e: Non-Extended Reach\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 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: 12184978\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735388389682,"sku":"12184978","price":60.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ad560b98c2405fdd6c519a879f1f712.jpg?v=1788772227","url":"https:\/\/voomisupply.com\/products\/accupro-12184978-3-16-inch-4-flute-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
