37-degree helix provides the efficient cutting action and chip evacuation required to machine aluminum and other nonferrous materials
Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool''s ability to remove material
High-speed steel (HSS) is a common general-purpose steel for cutting tools
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

Product Description

The Niagara Cutter AB910 uncoated high-speed steel ball nose end mill has two flutes and a 37-degree helix for milling aluminum and other nonferrous materials. The 37-degree helix angle provides more support behind the cutting edge than higher angles and increases cutting action and chip evacuation compared to the standard 30-degree helix. It efficiently cuts aluminum and other nonferrous materials, moving it up the spiral and away from the workpiece. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut.
High-speed steel (HSS) is a common, general-purpose steel for cutting tools; this tool has no coating or surface treatment. The tool’s ball nose creates contoured surfaces where sharp corners are not required. 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. Cutting diameter tolerance is +0.001” to -0.000''. The tool has a Weldon shank.
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.
