It features a 1\/16 inch cutting diameter, a 0.015 inch corner radius, and 4 right-hand spiral flutes with a 30-degree helix angle. The cutting edge is centercutting-capable, allowing plunge entry into workpieces. An AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life when cutting hard alloys, stainless steels, and high-temperature materials. This tool is used by CNC machinists and tool-and-die professionals running tight-tolerance finish and semi-finish passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for small-feature milling operations such as slot milling, profiling, and contouring in ferrous and non-ferrous materials. Its 1\/16 inch diameter and 3\/16 inch length of cut make it appropriate for fine detail work and restricted-access pockets where larger tooling cannot reach. The 1\/8 inch shank diameter fits standard ER and collet-style toolholders common in vertical machining centers and CNC routers. Micrograin carbide substrate provides rigidity and edge retention at small diameters. It is a single-end tool with right-hand cutting direction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance at 1\/16 inch diameter\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat and oxidation resistance during high-speed cuts\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress concentration and improves surface finish at part edges\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand spiral design for efficient chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank fits standard collet toolholders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement-style solid carbide corner radius end mill for use in standard 1\/8 inch collet or ER-style toolholders on CNC vertical machining centers, manual mills, and high-speed spindle systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Seat the 1\/8 inch shank fully into the collet and torque the nut to the toolholder specification before running. At 1\/16 inch diameter, this tool is sensitive to runout and excessive side load — verify collet condition and minimize overhang to avoid breakage during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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: +0.0002 \/ -0.0008 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.13 x 0.25 x 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12176900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737325470002,"sku":"12176900","price":32.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce698c0a4bf409bd2e0d01b2300950c3.jpg?v=1788787121","url":"https:\/\/voomisupply.com\/products\/accupro-12176900-corner-radius-end-mill-1-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
