• 35-degree helix angle provides increased cutting action and chip evacuation compared to the standard 30-degree helix
• Three flutes provide better chip-carrying capacity than four flutes and a finer finish than two, reducing the need for a second finishing cut in some applications
• Carbide can run at higher speeds than high-speed or cobalt steel, offering increased wear resistance and high cutting temperatures
• Ball nose end mills (also called ball end) create contoured surfaces­­­

The Niagara Cutter SB335 TiAlN-coated carbide ball nose end mill has a 35-degree helix angle and three flutes for use on stainless steel, titanium, and high-temperature alloys. 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 difficult-to-machine material, moving it up the spiral and away from the workpiece. The end mill’s three flutes provide better chip-carrying capacity than four flutes and a finer finish than two. They remove excess material from the cutting area and provide a third cutting edge to create an improved finish that may eliminate the need for a second finishing cut in some applications. The carbide substrate keeps the end mill harder and more wear resistant than high-speed or cobalt steel at high temperatures. The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and p erformance. It also offers increased hardness for abrasion resistance compared to TiN and may reduce the need for lubricants based on the application.

The tool’s center-cutting design allows the tool to plunge into the workpiece like a drill bit, while its ball end creates contoured surfaces where sharp edges are not required. It is best suited for slotting applications. The tool’s round shank accommodates a range of tool holders. Cutting diameter tolerance is +0.000” to -0.002”.

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 pr ovide 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.
