Niagara Cutter N88699 Cobalt Steel Ball Nose End Mill, Weldon Shank, TiCN Finish, Roughing and Finishing Cutting, 30-Degree, 6-Flute, 4.5" OAL, 1.500" Cut Diameter, 1.250" Shank Diameter

Description

The Niagara Cutter SPB540 TiCN-coated cobalt steel ball nose end mill has a 30-degree helix angle to shape contoured surfaces on a wide range of materials, including high-temperature alloys. The number of flutes varies; fewer flutes provide better chip-carrying capacity, while more flutes produce a finer finish. The TiCN coating lubricates the end mill for high-temperature stability, and provides more hardness and abrasion resistance than the TiN coating. The cobalt steel substrate can be run at faster speeds and stays sharp longer than high-speed steel tools, while offering greater resistance to heat and abrasion.

The 30-degree helix angle offers general-purpose machining. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The ball end creates contoured surfaces where sharp edges are not required. The center-cutting design has cutting teeth at the end of the tool. It can be fed straight into the workpiece like a drill bit for plunge cutting, and used for applications such as slotting and profiling. Cutting diameter tolerance is +0.001” to -0.000”. 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.
