Drilling
Hand control on the flex shaft handpiece is not steady and has a tendency to twist the drill with more force being applied to one side only resulting in uneven, oval and skew holes. The Drill-Str8 holds drill bits steady at the correct angle as seen in these drilling tasks of 6mm square bar, 3mm mild steel and 4mm stainless steel all done using a 1mm drill bit.
Polishing
Often, when working on the bench, small sections of the work have to be pre-polished in preparation for soldering task. Simply do this on the bench with your Drill-Str8.
