Spiral Router Bits for Steel and Stainless Steel
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.

Drill/Rout Router Bits
Drill, rout, and trim with the same bit. The unique shape on these bits was originally used for aircraft panels. They have a pointed end and spiral flutes, like a drill bit, making downward plunge cuts easier than with square-cut and straight-flute bits. The spiral flutes also leave a smoother finish. The flutes lift chips up from the workpiece for applications that require a clean finish on the bottom edge of the cut. Securely clamp your material before routing to prevent lifting.
These bits are made of high-speed steel for general purpose use. They can be used with hand tools, router tables, and CNC machines. These bits do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.
Bits with four flutes produce a smoother finish than three-flute bits.
