Built from micrograin carbide stock, this stub-length tool measures 0.1969 inches (5.00 mm) in diameter with a 0.3937-inch (10.00 mm) length of cut. The AlTiN finish improves heat resistance and extends tool life in dry or high-speed cutting conditions. Two spiral flutes at a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. The centercutting geometry allows plunge entry, giving machinists flexibility in toolpath programming without a pre-drilled start hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers, vertical mills, and manual knee mills running high-speed or conventional milling passes. The stub-length configuration adds rigidity, making it a strong choice for slotting, profiling, and pocketing in harder workpiece materials where deflection control is critical. The right-hand cut and right-hand flute orientation are standard for the majority of machining setups. Typical users include tool-and-die machinists, production CNC operators, and precision job shop technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat resistance in dry and high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eStub-length body reduces deflection in demanding milling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard machine spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in standard milling chucks, collet holders, and shrink-fit toolholders accepting a 6.00 mm (approximately 0.2362 inch) shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before loading or removing the tool. Use a calibrated torque wrench on collet nuts and verify runout with a dial indicator after seating the shank. Inspect the cutting edges for chips or wear before each use, as micrograin carbide is brittle and sensitive to improper handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1969 inches (5.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: 12181616\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737179357490,"sku":"12181616","price":46.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c7fe3fe316fc6ff66c013f07103b3ff.jpg?v=1788785280","url":"https:\/\/voomisupply.com\/products\/accupro-12181616-square-end-mill-0-1969-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
