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.
BOTTOM TAPS have a chamfer (lead) of 1–2 threads, the angle of the lead being around 18 degrees per side. They are used to produce threads close to the bottom of blind holes.

Finisher (Plug), 2-3 Threads Lead
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’.
All of our Taps are to class 2 Fit: These produce tapped holes of 6H, 4G, and 5G for Metric Threads, 2B for Unified threads and Medium fit for Whitworth and BA Threads.
