Niagara Cutter SB207 High-Speed Steel End Mill, General Purpose, Regular Length, TiAlN Coated, 2 Flutes, Ball End, 1-5/8" Cutting Length, 3/4" Cutting Diameter Reviews
Niagara Cutter SB207 High-Speed Steel End Mill, General Purpose, Regular Length, TiAlN Coated, 2 Flutes, Ball End, 1-5/8" Cutting Length, 3/4" Cutting Diameter Feature
- Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
- Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance, offering better heat resistance than TiN and TiCN coatings
- High-speed steel is compatible with a variety of materials
- Ball nose end mills (also called ball end) create contoured surfaces
- Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
The Niagara Cutter SB207 TiAlN-coated high-speed steel ball nose end mill provides the efficiency of two flutes and a 30-degree helix angle for general-purpose machining. The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness for abrasion resistance and may reduce the need for lubricants based on the application. (TiAlN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) High-speed steel (HSS) is a common, general-purpose steel for cutting tools and is compatible with a variety of materials.
The end mill’s 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. In contouring applications where the depth of cut is shallow, the end mill will create a fine finish. 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. The tool’s ball nose creates contoured surfaces, where sharp corners are not required, while the center-cutting design has cutting teeth at the end of the tool that support making pocket cuts, profiling and slotting. 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.
