YG-1 E5974 Carbide Ball Nose End Mill, Uncoated (Bright) Finish, 50 Deg Helix, 2 Flutes, 3" Overall Length, 0.5" Cutting Diameter, 0.5" Shank Diameter

The YG-1 E5974 uncoated carbide stub cut-length ball nose end mill has a 50-degree helix angle and two flutes for high-performance machining on aluminum, stainless steel, and copper. The stub length cutting edges increase tool strength and make it less likely to break in the material being machined. It is best used when depth of cut is shallow. The 50-degree helix angle offers increased cutting action compared to end mills with lower helix angles, as it moves excess material quickly up the spiral and away from the workpiece. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes into the material. The tool’s ball nose creates contoured surfaces where sharp corners are not required. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. Carbide is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. This tool has no coating or surface treatment. Cutting diameter tolerance is + 0.0000 to - 0.0010". The round shank accommodates a range of tool holders. End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool’s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts. YG-1 manufactures drills, taps, end mills, and rotary tooling. The company, founded in 1981, is headquartered in South Korea and has a U.S. office in Vernon Hills, IL.
