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.

The smooth flutes and sharp cutting edges on these router bits cleanly cut square slots, pockets, and edges in most plastics, including polyethylene, polycarbonate, and vinyl. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.

Also known as O-flute bits, the flutes on these bits are open and rounded for efficient chip removal when cutting aluminum. This also reduces heat to prevent melting or warping. Use these bits to create square slots, pockets, and edges. They are plunge cutting, letting you cut directly into the workpiece from above. They do not have a pilot, so guide your router along a straight edge when hand routing to make accurate cuts.

With a diamond coating, these bits resist wear when used on abrasive materials, making them last about 50 times longer than uncoated bits. Their sharp cutting edges and flute shapes are specifically designed to cut through tough materials such as composites with minimal resistance. This means less strain on your router and more control when cutting, leading to a smooth cut. Bits are made of solid carbide for longer tool life and faster cutting speeds than high-speed steel.
