Built from solid carbide with a titanium carbonitride (TiCN) coating, it delivers hardness and wear resistance across a range of ferrous and non-ferrous materials. The mill features a 0.1 inch corner radius, a 0.25 inch mill diameter, and a tip diameter of 0.05 inches. With two right-hand flutes and right-hand cutting direction, it is suited for finish passes and edge-breaking operations on machining centers and manual mills. Machinists and tool-and-die professionals are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision machining environments including job shops, production facilities, and toolroom operations. It applies to milling operations where a controlled corner radius is required on steel, aluminum, stainless, and similar materials. The double-end design extends tool life by providing two usable cutting ends. The 0.25 inch shank diameter is compatible with standard collet systems and end mill holders common to CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge on the cutting surfaces\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends, extending tool service life\u003c\/li\u003e\n\u003cli\u003e0.1 inch corner radius for consistent, repeatable edge rounding\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute geometry for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e0.25 inch shank diameter fits standard collet and end mill holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom end mill for use in any machine tool accepting a 0.25 inch shank diameter via collet, end mill holder, or equivalent workholding.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tool-holding practices. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Confirm runout with a dial indicator after tightening to minimize deflection and premature tool wear. Follow the tool and machine manufacturer guidelines for appropriate speeds, feeds, and depth of cut for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eEnd Configuration\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: 12180343\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755680104754,"sku":"12180343","price":82.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ae29ec1a424006325549d40e27ef078.jpg?v=1788958015","url":"https:\/\/voomisupply.com\/products\/accupro-12180343-corner-rounding-end-mill-1-4-in-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
