Also known as O-flute bits, these have a single open flute for efficient chip removal when cutting aluminum. Use them to create square slots, pockets, and edges.
Bits with straight-flutes are for general purpose use.
Spiral-flute bits make plunge cuts more easily than straight-flute bits and leave a smoother finish. Spiral-flute bits with upward chip removal lift chips up for applications that require a smooth finish on the bottom edge of the cut. Securely clamp the workpiece before routing to prevent lifting. Spiral-flute bits with downward chip removal push chips down for applications that require a smooth finish on the cut's top edge.
High-speed steel bits can be used with hand tools, router tables, and CNC machines. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.
Carbide bits have a longer life and faster cutting speeds than high-speed steel bits. Their extreme hardness makes them brittle, so they’re not recommended for use with hand tools. A highly rigid setup, such as a CNC machine, is necessary to keep bits from breaking.
