YG-1 E2110 High Speed Steel (HSS) Ball Nose End Mill, Weldon Shank, Uncoated (Bright) Finish, 30 Deg Helix, 2 Flutes, 3.875" Overall Length, 0.75" Cutting Diameter, 0.75" Shank Diameter

The YG-1 E1110 uncoated high-speed steel ball nose end mill has two flutes and a 30-degree helix angle for machining radius bottom slots, fillets, and special contours on a range of materials. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The tool’s ball nose creates contoured surfaces where sharp corners are not required. The 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. 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.High-speed steel (HSS) is a common general-purpose steel for cutting tools. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials. Cutting diameter tolerance is + 0.0010 to - 0.0000" for end mills with a different shank and cutting diameter and + 0.0015 to - 0.0000" for end mills with the same shank and cutting diameter. The tool has a Weldon shank. 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.
