Key Features

  • Corner rounding end mills are designed to take the edge off sharp corners
  • Four flutes produce a better finish than fewer flutes
  • Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel
  • Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
  • Non-center-cutting design supports peripheral milling and finishing

Product Description

The YG-1 E2237 uncoated cobalt steel corner rounding end mill has four flutes and a non-center-cutting design for machining fillets on a range of materials. Corner rounding end mills have a concave, curved indent on the cutting end to create a more rounded or less rounded corner, depending on the radius selected. Four flutes produce a better finish than fewer flutes. The non-center-cutting design is for applications such as peripheral milling and finishing.

Cobalt steel can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering resistance to heat and abrasion. This tool has no coating or surface treatment for use on a broad range of materials. 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.
