Key Features

  • Four flutes produce a better finish than fewer flutes and can machine material twice as fast as two-flute end mills in some applications
  • Ball nose end mills (also called ball end) create contoured surfaces
  • Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
  • Uncoated (bright) tools have no additional surface treatment or coating for general-purpose applications
  • Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures

Product Description

The Niagara Cutter CB430 uncoated carbide ball nose end mill provides the fine finish of 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 and can machine material twice as fast as two-flute end mills in some applications. 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.

With no coating or surface treatment, the tool features just the base (or substrate) material for a range of general-purpose applications. It can provide an economical alternative to higher-priced 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 +0.000 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 typically ranges 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.
