The Niagara Cutter CB330 TiCN-coated carbide ball nose end mill provides the versatility of three flutes and a 30-degree helix angle for general-purpose machining on aluminum and other nonferrous materials. Ball end creates contoured surfaces where sharp edges are not required, while center-cutting design allows the tool to plunge into the workpiece like a drill bit. While the tool is best suited for aluminum and other nonferrous materials, it can also be used to machine abrasive plastics, steel, stainless steel, and cast iron.
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 30-degree helix supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The TiCN coating offers the increased hardness and abrasion resistance required to machine aluminum and other nonferrous materials, providing more abrasion resistance than the TiN coating. Cutting diameter tolerance is +0.000” to -0.002”. The round shank accommodates a variety of holders.
End mills are designed to remove material and create three-dimensional shapes or 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 make plunge cuts similar to a drill bit.
Niagara Cutter has been designing and manufacturing precision cutting tools since 1954. Specializing in end mills, cutting mills, and saws, the company is based in New York and manufactures its tools at facilities in Pennsylvania and Massachusetts. This allows the company control over production, from substrate to coating, which is essential for customers in a variety of industries, especially aerospace and automotive.
