    Countersinking Drill Bits

    Drill and countersink holes at the same time. These bits create a surface that matches the profile of flat- and oval-head screws, so they sit flush with the edge of the hole once installed.

    Wear and heat resistant, these bits are versatile for use on a range of materials.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.

    Precise-Cut Counterboring Drill Bits

    Double-edged flutes keep these bits centered to drill straighter and smoother than other counterboring bits. In one pass, they drill and counterbore a hole to create a flat surface for the head of a socket head cap screw. Also known as subland drill bits.

    With no fixed diameters, one of these bits cuts holes of almost any size within a range. Slip a washer (not included) over the bit to set your diameter. The washer acts as stop while drilling, so choose a washer with an inner diameter that matches your desired hole size.

    Wear and heat resistant, these bits are versatile for use on a range of materials.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
    Style B—Require a 129/64" pilot hole to start drilling.
    3-Flat Shank—Three flat sides on the shank prevent the bit from slipping in the chuck of a drill press or portable drill.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    Step Drill Bits

    Drill multiple hole sizes using only one bit. These have steps with progressively larger diameters—the deeper they drill, the bigger the hole. Count the steps as you drill to achieve the proper size. These bits also deburr as they cut, so they're good for thin materials like sheet metal and plastic panels.

    Wear and heat resistant, these bits are versatile for use on a range of materials.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits. These are the best choice for hard-to-machine metals like stainless steel.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.
    3-Flat Shank—Three flat sides on the shank prevent the bit from slipping in the chuck of a drill press or portable drill.
    Hex Shank—Use with portable drills and drivers.

    Tougher and more wear resistant than high-speed steel, these bits last at least twice as long. They also can run up to 25% faster and at higher temperatures without damaging the bit on hard materials like nickel.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
    Hex Shank—Use with portable drills and drivers.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    Step Drill Bit Sets

    Cut a wide range of hole sizes with just a handful of bits. The bits in these sets have steps with progressively larger diameters—the deeper they drill, the bigger the hole. Count the steps as you drill to achieve the proper size. They also deburr as they cut, so these bits are good for thin materials like sheet metal and plastic panels.

    Wear and heat resistant, these bits are versatile for use on a range of materials.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits. These are the best choice for hard-to-machine metals like stainless steel.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
