With a 3\/16-inch cutting diameter and a 60-degree helix angle, this tool generates aggressive chip evacuation and smooth surface finishes on ferrous and non-ferrous materials. The TiCN (Titanium Carbonitride) coating extends tool life by increasing surface hardness and reducing friction at the cutting edge. At 2 inches overall length with a 5\/16-inch length of cut, this stub-length geometry minimizes deflection during tight-tolerance work. It is a single-end, right-hand cut tool suited for CNC machining centers and manual mills operated by skilled machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for slot milling, peripheral milling, and profiling operations where rigidity and dimensional accuracy are priorities. The stub-length design makes it particularly effective in low-clearance fixturing situations or when working close to a shoulder or step. The micrograin carbide substrate supports higher cutting speeds compared to standard-grade carbide, making it appropriate for production environments running hardened steels, stainless, and cast iron. Machinists in aerospace, automotive, and general manufacturing shops will find this tool fits standard ER and collet chuck toolholding systems sized for 3\/16-inch shank diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16-inch cutting diameter with a matching 3\/16-inch shank for direct collet chuck mounting\u003c\/li\u003e\n\u003cli\u003e60-degree helix angle promotes aggressive chip lift and improved surface finish\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases wear resistance and tool life on hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate enables higher speeds and feeds versus standard carbide\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for use in conventional CNC spindle configurations\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for any CNC or manual milling machine equipped with a collet or end mill holder sized for a 3\/16-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill from its holder. Use a properly sized ER collet, side-lock holder, or shrink-fit chuck to achieve accurate tool runout within the holder manufacturer's specified tolerance. Do not exceed the tool manufacturer's recommended cutting parameters for the specific workpiece material and machine setup.\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\u003eLength of Cut\u003c\/strong\u003e: 5\/16 inches (0.3125 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 (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 2500086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734761308466,"sku":"2500086","price":50.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/89fce40778e7595bc473c3efc13bdd4c.jpg?v=1788766722","url":"https:\/\/voomisupply.com\/products\/accupro-2500086-square-end-mill-3-16-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
