Is the Tormek HTK-706 Hand Tool Kit compatible with a Tormek T7?
Welcome to the forum, Al.
Yes, The HTK-706, and all the Tormek jigs, are compatable with all Tormek models, both in 250 mm (T7, T8, and the older SuperGrinds) and 200 mm (t4, T3, and earlier). The only exception to this is the T2, which is a specialized model for restaurants.
One of the hallmarks of Tormek is "no Tormek left behind".
