Quickly adjustable to any thread diameter and pitch within the size range indicated on the tool.
Applicable to all kinds of thread - inch, metric, RH or LH, fine or coarse.
A major advantage over taps is the ability to enter below the first damaged grooves - often at the start of the thread - and work in an outward direction.
The blade - made of high speed steel (62RC) - is guided by the existing undamaged thread to regroove the damaged section.
