- Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
- Square nose end mills (also called square end) create sharp, unrounded cuts
- Aluminum titanium nitride (AlTiN) coating lubricates the end mill for high-temperature stability and abrasion resistance, offering better heat resistance than TiN, TiAlN, and TiCN coatings
- Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures
- Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling

The Niagara Cutter C230M metric AlTiN-coated carbide square nose end mill has two flutes and a 30-degree helix angle for general-purpose machining on a range of materials. The two flutes have better chip-carrying capacity than more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The tool’s square end creates sharp, unrounded cuts, 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. 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 AlTiN coating resists heat better than TiN, TiAlN, and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. (AlTiN 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. Cutting diameter tolerance is +0.000 mm to -0.050 mm. 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.
