Key Features
- Double-end ball nose end mills create contoured surfaces and have cutting edges on both ends for longer tool life
- Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
- High-speed steel is compatible with a variety of materials
- Uncoated (bright) tools have no additional surface treatment or coating for use on a broad range of materials
- Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
Product Description
The Niagara Cutter DB260 uncoated high-speed steel double-end ball nose end mill has two flutes and a 30-degree helix angle for machining in a wide 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 ball nose end mills. The tool’s ball nose creates contoured surfaces where sharp corners are not required. 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.
High-speed steel (HSS) is a common, general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials and provide an economical alternative to coated tools. 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 and for used profiling, slotting, contouring, and creating pockets. The 30-degree helix angle supports general-purpose applications. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. Cutting diameter tolerance is +0.0000 to -0.0015". The 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.
