    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.
    Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear for three times the life of uncoated 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.

    Spiral Flute for Blind 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.
    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.
    Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes. When tapping brittle material like iron that creates fine or powdery debris, choose a straight-flute tap.
    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.
    Bottoming Chamfer—These taps have the shortest taper to thread close to the bottom of blind holes. They require the most force to turn, so they’re often used to finish holes started by plug-chamfer taps.

    Chip-Free Taps

    Image of Product. Front orientation. Taps. Chip-Free Taps.
    No flutes, no chips. Press threads into material for zero buildup to slow you down or damage the tap. Since these displace rather than cut material, they create stronger, cleaner threads. They require an exact hole size, however, or tapping can be difficult and result in weak threads. Fluteless taps are faster and require more force to drive than fluted taps, so they're commonly used in production work on a milling machine. Also known as cold-forming taps.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals.
    Titanium Carbon Nitride (TiCN) Coated—Resist heat, chipping, and wear for three times the life of uncoated 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.

    Spiral-Point Flute for Through Holes

    Chips won't slow you down when creating threads to join counter-clockwise rotating parts. Left-hand threads keep components such as flywheels and propellers from loosening and spinning off. These taps force chips through the hole so there’s no buildup to damage the threads or the tap. Since you don’t need to reverse taps to extract chips, they also form threads faster than standard left-hand taps.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    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.

    Chip-Clearing Pipe and Conduit Taps for Steel and Stainless Steel

    Made of a high-vanadium alloy, these taps are harder and more wear-resistant than other high-speed steel taps. The widely spaced flutes prevent buildup that can ruin threads and keep pipe and conduit from making strong connections. Also known as interrupted-thread taps.
