Niagara Cutter SLR600 High-Speed Steel End Mill, Heavy-Duty, Extra Long Reach, TiN Coated, 4 Flutes, Square End, 1" Cutting Length, 3/8" Cutting Diameter Reviews
Niagara Cutter SLR600 High-Speed Steel End Mill, Heavy-Duty, Extra Long Reach, TiN Coated, 4 Flutes, Square End, 1" Cutting Length, 3/8" Cutting Diameter Feature
- Extra-long-reach tools provide reach beyond that of standard-length end mills
- Number of flutes varies; fewer flutes have more chip-carrying capacity and more flutes produce a finer finish
- Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills
- High-speed steel is compatible with a variety of materials
- Square nose end mills (also called square end) create sharp, unrounded cuts
The Niagara Cutter SLR600 TiN-coated high-speed steel extra-long-reach square nose end mill has a 30-degree helix and a non-center-cutting design for peripheral milling and finishing applications in a wide range of materials. The number of flutes varies; fewer flutes provide better chip-carrying capacity, while more flutes produce a finer finish. Extra-long-reach end mills provide greater access to recessed areas of the workpiece than standard-length tools. 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.
The general-purpose TiN coating combines stability at high temperatures with hardness for wear protection, increasing tool life and performance compared to uncoated end mills. (TiN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) 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 creates sharp, unrounded cuts. The non-center-cutting design is for applications such as peripheral milling and finishing. 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.
