This item may be available in a different size, colour, scent, version or platform. Click below to be directed to product options:
The tool has a 3/16" shank diameter and a smaller cutting diameter, allowing better control over the size of the cut than larger tools when creating precise details and contours
Double-end square nose end mills create sharp, unrounded cuts and have cutting edges on both ends for longer tool life
Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
High-speed steel is compatible with a variety of materials
Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
The Niagara Cutter DR209 uncoated high-speed steel double-end square nose end mill has a 3/16” shank diameter, two flutes, and a 35-degree helix for general-purpose applications in a wide range of materials. The tool has a 3/16” shank diameter and a smaller cutting diameter, allowing better control over the size of the cut than larger tools when creating precise details and contours. The double-end design has cutting edges on both ends, allowing a new cutting surface to be substituted when the first shows wear, which doubles the tool’s life compared to single-end square end mills. 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. The 35-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 difficult-to-machine material, moving it up the spiral and away from the workpiece.
High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials. The tool’s square end has straight cutting edges that create sharp, unrounded cuts. 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 +0.000" to -0.001". 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.
