    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.
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as 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.
    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.
