Niagara Cutter CB430 Carbide End Mill, General Purpose, TiCN Coated, 4 Flutes, Ball End, 1/2" Cutting Length, 1/8" Cutting Diameter
The Niagara Cutter CB430 TiCN-coated carbide ball nose end mill has four flutes and a 30-degree helix angle for general-purpose machining on a range of materials. The tool’s ball nose creates contoured surfaces where sharp corners are not required, and 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. Four flutes produce a better finish than fewer flutes. 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 TiCN coating offers the increased hardness and abrasion resistance required to machine a broad range of materials, providing more abrasion resistance than the TiN coating. 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 +0.000” to -0.002”. The round shank accommodates a variety of 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.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.
