YG-1 E5980 Carbide Square Nose End Mill, TiCN Monolayer Finish, Finishing Cut, Non-Center Cutting, 45 Deg Helix, 3 Flutes, 3" Overall Length, 0.625" Cutting Diameter, 0.625" Shank Diameter

The YG-1 E5980TC TiCN-coated carbide stub-length square nose end mill has a 45-degree helix angle, three flutes, and a center-cutting design for high-performance machining on aluminum and other nonferrous materials. The stub length increases tool strength and makes it less likely to break in the material being machined. It is best used when depth of cut is shallow. The 45-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 end mill’s three flutes provide better chip-carrying capacity than four flutes and a finer finish than two. They efficiently remove excess material from the cutting area and provide a third cutting edge to create an improved finish that may eliminate the need for a second finishing cut in some applications. 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. The TiCN coating lubricates the end mill for high-temperature stability, and offers increased hardness and greater abrasion resistance than uncoated or TiN-coated tools. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. Cutting diameter tolerance is + 0.0000 to - 0.0005". 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.
