    Long-Reach Taps

    Image of Product. Front orientation. Taps. Long-Reach Taps.
    Thread holes that are hard to access or where obstructions make it difficult to turn a tap wrench. About twice as long other taps, these get you inside machines or through assemblies such as pulleys and belts. They 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.
    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—These taps thread 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.

    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 form threads faster.
    High-Speed Steel
    The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Plug Chamfer—The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, these are easier to turn than bottoming taps but require more force than taper taps.
    Uncoated—The economical choice, these won't last as long as coated taps.
    Spiral-Point Flute for Through Holes—Push chips ahead of the tap and out of through holes. Also known as gun 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.
    Plug Chamfer—The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, these are easier to turn than bottoming taps but require more force than taper taps.
    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.

    Long-Reach Pipe and Conduit Taps

    Reach into the deep recesses of your system and bypass obstructions to thread pipe and conduit. These are twice as long as standard taps but with the same shank diameter, so you don’t need a different holder. They have straight flutes that are good for most jobs.
