Product Features

  • Three flutes provide better chip-carrying capacity than four flutes and a finer finish than two, reducing the need for a second finishing cut in some applications
  • Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN and TiCN coatings
  • Carbide can run at higher speeds than high-speed steel, offering increased wear resistance at high cutting temperatures
  • Ball nose end mills (also called ball end) create contoured surfaces
  • Center-cutting design allows mill to plunge into material like a drill bit while also performing conventional surface milling

Product Details


Product Description

The Niagara Cutter CB330 TiAlN-coated carbide ball nose end mill provides the versatility of three flutes and a 30-degree helix angle for general-purpose machining on steel, stainless steel, and titanium. 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. The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness for abrasion resistance and may reduce the need for lubricants, based on the application. (TiAlN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) 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 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 angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. 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.
