Key Features

  • 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
  • Stub length increases the strength of the tool, making it less likely to break in the workpiece
  • 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
  • Titanium carbon nitride (TiCN) coating lubricates the end mill for high-temperature stability and offers better abrasion resistance than TiN coating

Product Description

The Niagara Cutter DS211 TiCN-coated high-speed steel stub-length double-end square nose end mill has a 3/16” shank diameter, two flutes, and a 35-degree helix for creating shallow cuts 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 stub length increases tool strength and makes it less likely to break in the material being machined. It is best used when depth of cut is shallow. The double-end design has cutting edges at both ends of the shank that can be swapped out when one side begins to show signs of wear, doubling the tool life compared to single-end tools. Two flutes have better chip-carrying capacity than end mills with more flutes, enhancing the tool’s ability to remove material. 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.

The TiCN coating offers increased hardness and greater abrasion resistance than uncoated or TiN-coated tools. High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety 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.
