It features a 1\/2 inch mill diameter, a 1 inch length of cut, and a 0.09 inch corner radius that produces a controlled edge radius on workpiece features, reducing stress concentrations and improving surface finish. The TiCN coating extends tool life in ferrous and non-ferrous materials by increasing surface hardness and reducing friction. With 4 right-hand spiral flutes and a centercutting geometry, this end mill handles both plunge and profile operations. It is installed and operated by machinists and tooling professionals in CNC and manual milling environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose profiling, slotting, and contouring in shop and production settings. The 1\/2 inch shank diameter fits standard ER and side-lock toolholders common to vertical machining centers and knee mills. The single-end configuration and 3 inch overall length make it appropriate for typical reach requirements in die-and-mold, aerospace, and general fabrication work. Micrograin carbide substrate supports higher surface footage and feeds compared to standard carbide grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for improved wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e0.09 inch corner radius reduces edge chipping and improves part surface finish\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with centercutting capability for plunge and profile milling\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 1\/2 inch shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2 inch shank corner radius end mill compatible with ER collet chucks, side-lock holders, and similar toolholding systems used on CNC vertical machining centers and manual knee mills accepting 1\/2 inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill. Confirm shank seating depth meets the toolholder manufacturer's minimum engagement specification before tightening. Inspect the cutting edges and corner radius for chips or damage before each use, and do not exceed the tool's rated depth-of-cut 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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (2.1250 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\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\u003eMaterial\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\u003eWeight\u003c\/strong\u003e: 0.28 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: 12182603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749705417010,"sku":"12182603","price":113.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a2efbd0a9ee97f988163fb3a6bbc3bf.jpg?v=1788909418","url":"https:\/\/voomisupply.com\/products\/accupro-12182603-corner-radius-end-mill-1-2-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
