- Corner radius end mills with extended-reach neck style have cutting edges with rounded corners to reduce chipping and provide longer tool life, and a longer neck to provide access to recessed areas of the workpiece
- 45-degree helix provides the efficient cutting action and chip evacuation required to machine aluminum and other nonferrous materials
- 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
- Wiper flat on cutting edges for a smoother finish than conventional end mills
- Titanium carbon nitride (TiCN) coating lubricates the end mill for high-temperature stability and offers better abrasion resistance than uncoated tools

The Niagara Cutter AN345R TiCN-coated carbide corner radius end mill with extended-reach neck style has three flutes, a 45-degree helix angle, a wiper flat, and cutting edges with rounded corners for high-performance cuts on aluminum and other nonferrous materials where tool reach is a problem. Corner radius on cutting edges reduces chipping and extends tool life. The extended-reach neck style provides greater access to recessed areas of the workpiece than tools with a standard neck style. The 45-degree helix provides increased cutting action and chip evacuation compared to end mills with lower helix angles, as it moves excess material quickly up the spiral and away from the workpiece. The 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. A wiper flat on the cutting edges provides a smoother finish to the workpiece than conventional end mills. The rounded area behind the cutting edge, called the cylindrical land, minimizes tool vibration when machining nonferrous materials.
The TiCN coating lubricates the end mill for high-temperature stability, and offers increased hardness and greater abrasion resistance than uncoated tools. 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 center-cutting design has cutting teeth at the end of the tool, so it can be fed straight into the workpiece like a drill bit. The tool has an eccentric primary relief feature that provides better support behind the cutting edge than a flat relief, reducing tooth breakage in deep cuts. Cutting diameter tolerance is +0.000" to -0.002". The round shank accommodates a range of tool 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.
