    Chip-Clearing Tap Sets

    A range of sizes that remove chips so they don’t ruin the threads or jam the tap. The spiral-point flutes force chips through the hole to prevent buildup and create threads faster than standard taps. Also known as gun taps.

    The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Gold Oxide—The finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.

    Chamfer Set

    The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic. These sets include one of each chamfer type: Taper for starting holes and threading through holes; plug for through holes and blind holes; and bottoming for cutting the closest to the bottom of any hole.
    Uncoated—The economical choice, these won't last as long as coated taps.

    Taps

    Image of Product. Front orientation. Taps. Taps.
    Cut threads into holes so screws, bolts, and rods fit snugly. Our basic taps have straight flutes that are good for most jobs.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Uncoated—The economical choice, these won't last as long as coated taps.
    Taper Chamfer—Good for both starting holes and threading through holes. These taps have the longest taper to gradually engage with the material, reducing the force needed to turn them. They can't reach the bottom of blind holes, however, so you will likely need to finish with a bottoming-chamfer tap.
    Plug Chamfer—Our go-to chamfer type, these thread both through holes and blind holes. The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, they're easier to turn than bottoming taps but require more force than taper taps.
    Bottoming Chamfer—Cut all the way to the bottom of blind holes with taps that have the shortest taper. Since these require the most force to turn, they’re often used to finish holes started by taper- or plug-chamfer taps.
    Number of Flutes—Taps with fewer flutes have more space to capture chips, so you won’t have to clear them as often. However, they can be more difficult to keep straight in the hole.
    Taps Sold as Sets—Include one tap of each chamfer type.

    Chip-Clearing Taps

    Spiral-Point Flute for Through Holes

    Remove long, stringy chips to produce cleaner threads than standard taps. The flute design prevents buildup to protect the quality of the threads and avoid damage to the tap. Since you don’t need to reverse these taps to extract chips, they also create threads faster.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Uncoated—The economical choice, these won't last as long as coated taps.
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.
    Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear for three times the life of uncoated taps.
    Spiral-Point Flute for Through Holes—Push chips ahead of the tap and out of through holes. Also known as gun taps.
    Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.
