With a 19\/64 inch (0.2969 inch) cutting diameter and a 2-inch overall length, this stub-length tool is built for rigidity in tight-clearance setups. The TiCN (titanium carbonitride) coating improves hardness and wear resistance compared to uncoated carbide. Two spiral flutes with a 40-degree helix angle promote efficient chip evacuation. The micrograin carbide substrate supports sharper cutting edges and longer tool life in ferrous and non-ferrous materials. This end mill is centercutting, allowing plunge entry directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling, slotting, and profiling operations on machining centers, CNC mills, and manual knee mills. The stub length-of-cut design reduces deflection, making it appropriate for applications requiring dimensional accuracy in close-tolerance work. The right-hand cut, right-hand flute configuration is standard for conventional and climb milling on most spindle setups. Machinists, toolmakers, and CNC operators in job shops, production facilities, and maintenance environments are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended edge life and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eStub length-of-cut (1\/2 inch LOC) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or new-install square end mill for toolholders and collets accepting a 5\/16 inch shank diameter.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the shank to the full depth recommended by the toolholder manufacturer to maintain runout tolerance. Do not exceed the toolholder's rated RPM or the end mill manufacturer's recommended cutting parameters for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 19\/64 inch (0.2969 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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: 5\/16 inch (0.3125 inch)\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12181642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732676149554,"sku":"12181642","price":59.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71ff9b3376bb73721d9a486fabdfa617.jpg?v=1788745631","url":"https:\/\/voomisupply.com\/products\/accupro-12181642-square-end-mill-19-64-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
