    Nonsparking Drill Bits

    Drill safely in flammable environments. Made of beryllium copper, these bits won’t create sparks that could ignite upon contact with combustible vapors or residues. They're Factory Mutual (FM) approved and help you meet OSHA requirements in areas where flammable materials are present.
    Do not use these bits in direct contact with acetylene. Dust from beryllium copper can be toxic, so don't grind or sharpen them.

    Spiral Flute

    Round Shank

    Standard

    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

    2 Channels

    Create very small holes, including pilot holes to run EDM (electrical discharge machining) wire through. For use in hole-popping EDM machines.
    Also known as spark machining, EDM uses electrical current to erode a metal workpiece to a desired shape.
    Copper—Copper electrodes last longer and are better for use on extremely hard materials, such as carbide, sintered diamond, and invar and kovar nickel alloys.
    1 Channel—Electrodes with one channel are best for creating through holes.
    2 Channels—Electrodes with two channels are best for creating closed-end holes. The internal channels disintegrate material left at the bottom of a closed-end hole.
