HMT VERSADRIVE IMPACTADIE
Patent pending
Thread bar, studs and conduit on site with your impact wrench.
A guide sized to the bar holds the hex die square as you drive it, so the thread starts straight first time: no die stock, no cross-threading, up to 15x faster than threading by hand. Create new threads, repair damaged ones up to a shoulder, or clean galvanizing and rust out of existing threads.
