The Niagara Cutter REC700 TiCN-coated cobalt steel fine-pitch rougher end mill has a 30-degree helix and is suitable for machining soft, gummy materials such as aluminum or other nonferrous metals. The number of flutes varies by diameter to optimize the feed and cut rate. 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 end mill produces a rough finish that can be smoothed by a second finishing cut. The TiCN coating offers increased hardness and greater abrasion resistance than uncoated tools. 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.
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 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 corner chamfer on the cutting edges to provide more strength than standard square end tools in applications where cutting forces are high. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit, and used for applications such as slotting and profiling. Cutting diameter tolerance is +0.003 to -0.000" for cutting diameters 1 or under; +0.006 to -0.000 for cutting diameters over 1 . 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.
