We supply only quality taps and dies. Generally Sutton, Bordo, Goliath, APEX UK.
Available in 3 leads:
Taper: 8 - 10 leads of thread used for starting new threads
Intermediate: Less tapered, 4 - 5 leads, used to follow a Taper tap or for restoring threads
Bottoming: Very little taper 1 1/2 - 2 1/2 leads, so will cut a new thread to the bottom of a blind hole, but the lack of taper makes starting a new thread difficult.
A tap set is available and it it simply three times the price of a single tap.

Good quality tool, used in #29 pre-drilled hole in Al workpiece. Excellent performance with clean cut thread following about 5 initial turns.
