Discount Niagara Cutter DP530 Cobalt Steel End Mill, General Purpose, Regular Length, Uncoated (Bright), 2
The Niagara Cutter DP530 uncoated cobalt steel double-end square end mill has two flutes and a 30-degree helix angle for general-purpose machining on a range of materials. The double-end design has cutting edges on both ends, allowing a new cutting surface to be substituted when the first shows wear, which doubles the tool’s life compared to single-end square nose end mills. The two flutes have better chip-carrying capacity than end mills with more flutes, while offering additional support when the tool goes deep into the material in applications with a high depth of cut. 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. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials.
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 tool’s square end has straight cutting edges to create sharp, unrounded cuts. 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, profiling, and pocketing. Cutting diameter tolerance is +0.0000” to -0.0015”. 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 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.
