Top Industrial Quality Tools !!!!

HAND TAPS (ISO 529)
These are NEW professional quality ground finish straight flute general purpose tools which can be used for both machine or hand tapping. They are generally the most economical tool for use on production runs, but are best on materials that produce chips, or where the swarf breaks readily. Where deep holes are to be tapped, in materials which produce stringy swarf, other types of taps may be needed, especially for coarse threads.

  SECOND TAPS have a lead of 3-5 threads    at 8 degrees    per side. They are the most popular and can be used    for through holes, or blind    holes where the thread does not need    to go right to the bottom.

IMPORTANT NOTE ON TERMINOLOGY! In the       U.K. bottom taps are often referred to as ‘plugs’. In North America second    taps    are often referred to as ‘plugs’! This can easily lead to    confusion. To avoid    problems when ordering it is best to use the    terms bottom, second and taper.
    Another variation is that second taps are sometimes referred to as ‘intermediate’,       and taper taps can be called ‘firsts’.
