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 cutting, threading, or reaming pipe. Type I is a hand-held drive that can also be adapted for turning large valves and geared threaders. Type II is a portable power drive unit that is normally bolted to a portable stand and used for threading pipe and bolt stock. This unit uses a mounted carriage with attached die-heads, reamer, and cutter, or coupled to a geared threader. Both power drives are intended for use in the shop or on the construction site due to their portability.
