Niagara Cutter DLH590 High-Speed Steel End Mill, General Purpose, Uncoated (Bright), 4 Flutes, Double Square End, 1-7/8" Cutting Length, 7/8" Cutting Diameter Reviews
Niagara Cutter DLH590 High-Speed Steel End Mill, General Purpose, Uncoated (Bright), 4 Flutes, Double Square End, 1-7/8" Cutting Length, 7/8" Cutting Diameter Feature
- Left-hand cut, left-hand helix square end mills are used to make mirror image parts on multi-spindle machines and in applications where a counter-clockwise cutting action is preferred
- Double-end square nose end mills create sharp, unrounded cuts and have cutting edges on both ends for longer tool life
- Four flutes produce a better finish than fewer flutes
- 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 DLH590 uncoated high-speed steel double-end square nose end mill with left-hand cut and a left-hand helix has four flutes, a 30-degree helix, and a non-center-cutting design for general-purpose peripheral milling and finishing applications in a wide range of materials. Left-hand cut, left-hand helix end mills are used to make mirror image parts on multi-spindle machines and in applications where a counter-clockwise cutting action is preferred. 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 tool’s square end creates sharp, unrounded cuts. Four flutes produce a better finish than fewer flutes. 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.
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 non-center-cutting design is for applications such as peripheral milling and finishing. Cutting diameter tolerance is +0.001" to -0.000"; when the shank and flute diameters are the same, the cutting diameter tolerance is +0.0000” to -0.0015”. 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.
