It carries a 1\/2 inch cutting diameter with a 5\/8 inch length of cut and a 60-degree helix angle, which promotes aggressive chip evacuation and reduces cutting forces on harder materials. The micrograin carbide substrate improves edge retention at elevated feeds and speeds. A TiCN (titanium carbonitride) coating adds surface hardness and lubricity, extending tool life compared to uncoated carbide. Licensed machinists, tool-and-die shops, and CNC operators use this mill for slotting, profiling, and peripheral milling applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits stub-length milling applications where rigidity and reduced deflection are the priority. The double-end design provides two usable cutting ends, offering additional value for high-volume production environments. With a 1\/2 inch shank diameter and 3-inch overall length, it seats securely in standard ER collet chucks, shrink-fit holders, and side-lock holders. Right-hand cutting and right-hand flute direction are standard for conventional CNC machining centers. The centercutting geometry allows plunge cuts directly into the workpiece without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end configuration provides two cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003e60-degree helix angle promotes efficient chip evacuation in harder materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and lubricity for extended tool life\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers superior edge retention\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry supports direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flutes suit standard CNC machining setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 1\/2 inch bore ER collet chucks, shrink-fit holders, and Weldon side-lock holders used on conventional CNC vertical machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and the machine in an e-stop or locked-out state. Ensure the shank is fully seated to the recommended engagement depth in the tool holder and that the collet or set screw is torqued to the holder manufacturer's specification. Inspect runout with a dial test indicator before production use. Never exceed the manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\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\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 2500254\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":52126692475186,"sku":"2500254","price":180.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e101aab241ef7cb38b61569ebc56dd3.jpg?v=1790088488","url":"https:\/\/voomisupply.com\/products\/accupro-2500254-square-end-mill-1-2-in-3-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
