The 792ALX threader is a heavy-duty production caliber machine. The LX series is capable of producing class 2A threads from 1/4" Bolt thread up to 2" NC Bolt and 2" NPT Pipe in a single pass. Production speed bolt threading and threading bent material is no problem for the 792ALX because the material stays stationary and is available in Standard, Long and Extra Long Bed models.

Semi-Automatic Rotating Diehead

Rotating style Diehead keeps material still and handlers safe. Stationary material also allows for threading of bent pipe, rod and conduit. Open construction of head permits chips to fall away as thread is being cut. The yoke actuated by the movement of the vise carriage automatically controls the opening and resetting of the die-head. Head is fully adjustable for over and undersize thread.

Vise Carriage

Quick-acting, open type vise with hardened steel insert gripping jaws and auxiliary jaws for diameters under 1/2". This smooth working vise permits easy loading, insures positive gripping and automatic centering.

Adjustable Diehead Threading Stop

Easy to change quick-setting adjustable stop automatically opens the die-head at the desired thread length for Pipe & Bolt making repetative cuts of the same length easy and accurate.

Three Bed Sizes Available

With three bed sizes available you can find the perfect balance between maximum thread length capabilities and the foot print of your new machine.
