The Tormek TT-50 Truing Tool keeps your grindstone round and flat.
Its diamond tip takes the top layer off the stone wherever there's too much material. You set the depth of cut with the Micro Adjust on the Universal Support, which is marked every 0.25 mm (0.01 in). It works on every Tormek wheel except the diamond wheels, and the diamond tip can be replaced when it wears. It fits any Tormek with a Universal Support; machines without Micro Adjust can be updated with the US-105 (T-8) or US-103 (T-4). It is cast zinc and comes assembled.
Engineer Torgny Jansson founded Tormek in 1973 to build a modern version of the old Swedish water-cooled grindstone. The name is short for Torgny's Mekaniska, and the very first model was driven by an electric hand drill. Tormek is based in Lindesberg, Sweden, where all of its product development, engineering and production still take place.
