Long-Reach Carbide Rounded-Edge Square End Mill
Manufacturer part: 8899A23
Also known as torus end mills, these tools have a rounded edge and long, thin neck for precision contouring in molds and dies. Coated with titanium aluminum nitride (TiAlN), they have the hardness, wear resistance, and temperature resistance needed for cutting tool steel, hardened steel, and iron. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. All are center cutting, allowing plunge cuts into a surface.
