scope:

This commercial item description (CID) covers hand-held, and stand-mounted power drives powered by integral or separately mounted electric motors for cutting threads on pipe and bolt stock. Included are optional items to tailor the power drive to perform various functions. The power drives provide rotational power to turn pipe and bolt stock or turn geared threaders for threading, cutting, and reaming pipe. The type I is a hand-held drive which can also be adapted for turning large valves and turning geared threaders. Type II is a portable power drive unit which is normally bolted to a portable stand and used for threading pipe and bolt stock using a mounted carriage with attached die-heads, reamer, and cutter, or coupled to a geared threader. Both power drive units are intended for use in the shop or on the construction site due to the portability.
