These Robert Sorby thread cutters were designed in conjunction with master turner Robert Sorby and have been specially produced for cutting in wood.
Thread cutters are available in matching pairs for internal and external threads.
The Relief Tool is a handy accessory to cut the relief in the bottom of female threads whilst the Tool Support enables extra access.
The gauge is extremely useful for any box maker as it enables the accurate sizing of the lid whether threaded or a push fit.
One of the anvils gives a 1:1 measurement for a push fit whilst the other three accurately give the size required for the specific depth of thread - whether 10tpi, 16tpi or 20tpi.
