YG-1 EIB07 Carbide Micro Ball Nose End Mill, Diamond-Like Finish, 30 Deg Helix, 4 Flutes, 3" Overall Length, 0.0312" Cutting Diameter, 0.125" Shank Diameter

The YG-1 EIB07 diamond-coated carbide long-reach ball nose end mill has four flutes and a 30-degree helix angle for high-performance machining on graphite, wrought aluminum, plastic, wood, brass, and other nonferrous and nonmetallic materials. The long-reach shank provides greater access to recessed areas of the workpiece than tools with a standard shank length. (Feed should be reduced.) Four flutes produce a better finish than fewer flutes. The tool’s ball nose creates contoured surfaces where sharp corners are not required. The 30-degree helix angle 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. The high hardness of the diamond coating provides high wear resistance compared to other coatings for increased tool life and performance on abrasive materials. It also produces a smoother finish on the recommended materials than other coatings. 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 - 0.0012". 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.
