With a 1\/2 inch diameter, a 1 inch length of cut, and a 0.06 inch corner radius, this tool produces smooth, radiused profiles on workpiece corners while maintaining tight tolerances. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and stable cutting performance. Manufactured from micrograin solid carbide, the 12183559 delivers the rigidity and wear resistance required for demanding cutting applications. It is a single-end, centercutting tool, meaning it can plunge directly into material as well as cut along the periphery.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills where corner radii and edge-breaking profiles are required. The bright, uncoated finish makes it appropriate for general-purpose milling in ferrous and non-ferrous materials. With a 4 inch overall length and a 1\/2 inch shank diameter, it fits standard tool holders used in production shops, tool rooms, and maintenance machining environments. Machinists and CNC operators performing die work, mold work, or precision part finishing will find this geometry well-matched to those applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.06 inch corner radius reduces stress concentrations and produces consistent radiused profiles\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction provides high rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for a broad range of general-purpose milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 1\/2 inch straight shank tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout after installation using a dial indicator before beginning any cut.
