The Niagara Cutter SMW835 uncoated (bright) cobalt steel metric end mill has two flutes, a 30-degree helix angle, and a square end to machine a wide range of materials. The cobalt steel substrate can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering greater resistance to heat and abrasion. With no coating or surface treatment, the tool features just the base material for use on a broad range of materials. It can provide an economical alternative to higher-priced coatings.
The end mill’s 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 30-degree helix angle offers general-purpose machining. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The tool’s square end has straight cutting edges that create sharp, unrounded cuts, while the center-cutting design has cutting teeth at the end of the tool that support making pocket cuts, profiling, and slotting. Cutting diameter tolerance conforms to DIN specifications 327 and 1835. The end mill 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.
