Niagara Cutter REM710 Cobalt Steel End Mill Set, Coarse-Pitch Roughing, TiN Coated, 4 Flutes, 6-piece Reviews
Niagara Cutter REM710 Cobalt Steel End Mill Set, Coarse-Pitch Roughing, TiN Coated, 4 Flutes, 6-piece Feature
- Roughing end mills have chip-breaking cutting edges that remove material in less time than conventional end mills
- Coarse-pitch tooth design is suitable for machining mild and cold-rolled steels
- Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills
- Cobalt steel resists abrasion and high cutting temperatures, and has higher feed rates than high-speed steel
- Square nose end mills (also called square end) create sharp, unrounded cuts
Each Niagara Cutter REM710 TiN-coated cobalt steel coarse-pitch rougher end mill in this six-piece set has four flutes and a non-center-cutting design, and is suitable for machining mild and cold-rolled steels. The coarse-pitch tooth design has chip-breaking cutting edges that remove more material in less time than conventional end mills to support heavier cuts at higher speeds. The six-piece set includes one each of these cutting diameters: 3/16”, 1/4", 5/16”, 3/8”, 1/2", and 5/8”.
Each end mill has four flutes to optimize the feed and cut rate, and produces a rough finish that can be smoothed by a second finishing cut. The 30-degree helix angle balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The tool’s square end creates sharp, unrounded cuts, and has a chamfer end to strengthen the cutting edge. The non-center-cutting design is for applications such as peripheral milling.
Rougher end mills are special-purpose tools whose chip-breaking cutting edges create small chips for heavy cuts and remove more material in less time than conventional end mills, with minimal vibration (chatter). 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. The cobalt steel substrate can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering resistance to heat and abrasion. Cutting diameter tolerance is +0.003” to -0.000". Each 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.
