Product Description

The Niagara Cutter EX350 TiN-coated cobalt steel square nose end mill combines powdered-metal cobalt steel, flutes with low-friction cutting edges, and a 35-degree helix angle for milling difficult-to-machine materials. The number of flutes varies; fewer flutes provide better chip-carrying capacity, while more flutes produce a finer finish. Powdered-metal cobalt is high-speed steel (HSS) with 8.5% cobalt, which provides better heat and wear resistance than high-speed steel, and increased toughness when compared to general-purpose cobalt.

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. (TiN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) The cutting edge is treated with extra grinding passes, minimizing surface roughness and creating a low-friction surface on the cutting edge to help prevent chips from sticking to the tool. The 35-degree helix angle provides more support behind the cutting edge than higher angles and increases cutting action and chip evacuation compared to the standard 30-degree helix. It efficiently cuts radiuses, slots, fillets, special shapes, and contours on difficult-to-machine material, moving it up the spiral and away from the workpiece.

The tool has an eccentric primary relief feature that provides better support behind the cutting edge than a flat relief, reducing tooth breakage in deep cuts. The center-cutting design has cutting teeth at the end of the tool, so it can be fed straight into the workpiece like a drill bit. The tool’s square end creates sharp, unrounded cuts. Cutting diameter tolerance is +0.001" to -0.000". This tool 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 two facilities in Pennsylvania and Massachusetts. This allows the company control over production, an essential benefit for customers in a variety of industries, especially aerospace and automotive.

Features & Highlights

  • Powdered-metal cobalt steel offers toughness and resistance to heat and wear
  • Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills
  • 35-degree helix angle provides increased cutting action and chip evacuation compared to the standard 30-degree helix
  • Number of flutes varies; fewer flutes have more chip-carrying capacity and more flutes produce a finer finish
  • Low-friction cutting edge reduces chip buildup
