Niagara Cutter SR545 Carbide End Mill, for Titanium Roughing, TiN Coated, 7 Flutes, 0.025" Chamfer End, 3-1/4" Cutting Length, 1-1/4" Cutting Diameter

Niagara Cutter SR545 Carbide End Mill, for Titanium Roughing, TiN Coated, 7 Flutes, 0.025" Chamfer End, 3-1/4" Cutting Length, 1-1/4" Cutting Diameter

• Roughing end mills have chip-breaking cutting edges that remove material in less time than conventional end mills
• Fine-pitch tooth design and corner chamfer on cutting edges provide the strength to machine titanium
• 45-degree helix provides efficient cutting action and chip evacuation
• Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills
• Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures

The Niagara Cutter SR545 TiN-coated carbide square nose fine-pitch roughing end mill has a 45-degree helix angle and a corner chamfer on the cutting edges for high-performance peripheral roughing cuts on titanium. 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 fine-pitch tooth design and corner chamfer on the cutting edges provide the strength to cut difficult-to-machine titanium. The 45-degree helix angle offers increased cutting action compared to end mills with lower helix angles, as it moves excess material quickly up the spiral and away from the workpiece. The number of flutes varies to optimize the feed and cut rate. The end mill produces a rough finish that can be smoothed by a second finishing cut. The tool is designed for peripheral milling up to 25 percent of its cutting diameter.

T he 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 carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The tool’s square end creates sharp, unrounded cuts. 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. Cutting diameter tolerance is +0.000" to -0.003". The round shank accommodates a range of tool holders.

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 fro m 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.
