It also offers increased hardness for abrasion resistance and may reduce the need for lubricants based on the application. The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It balances lower angles’ strong cutting edge for difficult-to-machine materials with higher angles’ increased cutting action. The 30-degree helix angle supports general-purpose applications. Four flutes produce a better finish than fewer flutes. The tool’s ball nose creates contoured surfaces where sharp corners are not required, and 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.
The Niagara Cutter CB430 TiAlN-coated carbide ball nose end mill has four flutes and a 30-degree helix angle for general-purpose machining on a range of materials.
