    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.
    Cobalt Steel—These taps resist higher temperatures and and last twice as long as high-speed steel taps. They thread hard materials such as iron and hardened steel without damaging their cutting edges.
    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.
    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.
    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.

    Spiral Flute for Blind Holes

    Long, gummy strands from soft metals won’t get stuck on the tap or in the hole. With two layers of slippery coating over spiral flutes, these taps prevent chip buildup that can harm the threads and the tap.
    Cobalt Steel—Tough and wear resistant, cobalt taps last twice as long as high-speed steel. They also can run at higher temperatures without damage to their cutting edges.
    Spiral Flute for Through Holes—Left-hand flutes push chips ahead of the tap and out of through holes.
    Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes.
    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.

    Long-Reach Chip-Clearing Taps

    Image of ProductInUse. Front orientation. Taps. Long-Reach Chip-Clearing Taps.
    Push out chips while threading holes that are hard to reach or obstructed. These taps are double the length of standard taps to reach inside machines or through assemblies such as pulleys and belts. 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.
    Cobalt Steel—These taps resist higher temperatures and and last twice as long as high-speed steel taps. They thread hard materials such as iron and hardened steel without damaging their cutting edges.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than 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.

    Spiral Flute for Blind Holes

    Avoid heat buildup that can deform material and prematurely wear taps when threading nickel alloys. The body on these taps narrows closer to the flutes for better coolant flow and less contact with the workpiece. Spiral flutes prevent stuck chips that can slow you down and decrease the quality of the threads.
    Cobalt Steel—Tough and wear resistant, cobalt taps last twice as long as high-speed steel. They also can run at higher temperatures without damage to their cutting edges.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.
    Spiral Flute for Through Holes—Left-hand flutes push chips ahead of the tap and out of through holes.
    Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes.
    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.

    Spiral Flute for Blind Holes

    Sharp, angled flutes cut through tough titanium alloys while reducing heat and preventing clogs. These taps draw out chips gradually to create clean threads and protect the tap from jamming or breaking.
    Cobalt Steel—Tough and wear resistant, cobalt taps last twice as long as high-speed steel. They also can run at higher temperatures without damage to their cutting edges.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.
    Spiral Flute for Through Holes—Left-hand flutes push chips ahead of the tap and out of through holes.
    Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes.
    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.

    Cobalt Steel—These taps resist higher temperatures and and last twice as long as high-speed steel taps. They thread hard materials such as iron and hardened steel without damaging their cutting edges.
