ULTRALITE NUTPLATE DRILLMOTORS The Spacematic ULTRALITE® Nutplate Drill Motor II is a pneumatic portable hand held tool that drills and countersinks the two rivet holes which are subsequently used to mount various types of nutplates. The tool is completely automatic in that operation consists of inserting the colletmandrel assembly into the pre-drilled pilot hole and activating the trigger. The collet-mandrel assembly grips the work piece, holding the tool securely while both drill-countersincks are simultaneously rotated and advanced into the work piece under controlled feed conditions. When both drill-countersinks have reached their pre-set depth, releasing the trigger completes the cycle.
