    Straight and Spiral Router Bits for Aluminum

    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.

    High-speed steel bits can be used with hand routers, router tables, and CNC machines.
    Straight Flute—Bits with straight flutes are for general purpose use. They quickly remove material, leaving a rough finish.
    Upward Chip Removal—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.

    Zirconium-nitride (ZrN) coated carbide bits have a smoother cutting edge than uncoated bits, so they generate less friction when cutting. This helps keep temperatures down when cutting at high speeds, minimizing material buildup and extending the life of the bit. 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.
    Spiral Flute—Bits with spiral flutes leave a smoother finish than straight-flute bits and make plunge cuts more easily.
    Upward Chip Removal—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.
    2 Flutes—Bits with two flutes produce a smoother finish.

    Ball-End Router Bits

    Image of Product. Front orientation. Router Bits. Ball-End Router Bits .
    For smooth contour carving in wood, plastic, and aluminum, these bits have a ball-nose design. All are made of solid carbide for a long tool life and fast cutting speeds. The extreme hardness of carbide bits means they are brittle, so they're not recommended for use with hand tools. A highly rigid setup, such as a CNC machine, is necessary to prevent the bit from breaking. The spiral flutes pull chips up from the workpiece while making cuts; securely clamp your material before routing to prevent lifting.

    Use carbide bits for longer tool life and faster cutting speeds than high-speed steel.
    Bottom Pilot—Bottom-pilot bits trim material from an upper layer of the workpiece so that it is flush with the layer below. In addition to flush trimming, they can be used to cut along a template placed below the workpiece.
    Spiral Flutes—Bits with spiral flutes leave a smoother finish than straight-flute bits and make plunge cuts more easily (for plunge-cutting bits).
    Ball Bearing—Ball-bearing pilots guide the bit for accurate cuts and produce less friction than solid pilots for smoother operation.
    Pilot Location—Pilot location describes the position of the pilot when the bit is used for hand routing. The pilot location is reversed when using the bit with a router table.
