The aluminum-titanium-nitride (AlTiN) coating on these bits resists heat and wear when cutting steel and stainless steel. They have a square cut style for creating slots, pockets, and edges. They're made of solid carbide for longer tool life and faster cutting speeds than high-speed steel. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the bit from breaking. With spiral flutes, they leave a smoother finish than straight-flute bits and are good for making plunge cuts. The flutes lift chips up from the workpiece for applications that require a smooth finish on the bottom edge of the cut. Securely clamp your material before routing to prevent lifting. Bits with more flutes produce a smoother finish.
