A method for abrading or polishing and reaming the terminal ends of tubing or fittings using a hand-held electrically powered device having a rotating member capable of accepting a standard shaft which has attached to it a male and female abrasive member which will polish or abrade the inside and outside of a length tubing or fitting respectively uses the same tool. Also attached to the standard shaft is a reamer for removing unwanted material from the end of the length of tubing. All of these members are attached at the same end of the standard shaft, thereby allowing all the operations to be performed at one time on each tubing or mating fitting member. In addition, the standard shaft may be connected to a clutch release mechanism allowing the tool mechanism to disengage upon the application of excessive torque.
