The Niagara Cutter SPC408 TiCN-coated cobalt steel square nose end mill has a 30-degree helix angle for milling a wide range of materials, including high-temperature alloys. The number of flutes varies; fewer flutes provide better chip-carrying capacity, while more flutes produce a finer finish. The TiCN coating offers increased hardness and greater abrasion resistance than uncoated or TiN-coated tools. 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.
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 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 is +0.001” to -0.000”. 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.

First, a simple plea to question each review to make sure they know what they're talking about before taking their opinion seriously. One individual is saying it will chatter taking a *FULL DIAMETER* depth of cut axially, and 0.005" radially. Another is claiming it burnt out running a half inch end mill against hardened steel (very hard, actually) at 870RPM. This is HSS folks, not carbide.Personally I won't take HSS above 300-400RPM in steel, especially on a hobbiest machine. and for that, when you actually observe the speeds and feeds as reccomended in the machineries handbook or from the manufacturer....Niagara is ALWAYS superior. I have yet to be dissapointed on anything I've purchased from them, and this cutter is absolutely no exception.FWIW, I took actual roughing cuts using this exact endmill in 304 stainless that had already been work-hardened. I was taking 0.100" depth (axially), 1/4 depth radially (so around 0.120"), with a relatively low spindle speed (about 200RPM) and a definitely slow feed, and it performed beautifully. No chatter (on a benchtop machine), smooth cuts, the chips were precicely the way you want them (little 6's for the most part).Great product!!

Very good for creating a smooth "face" on metal.
