Stay with a drill roto-brush.
Don't really like the 1/4" hex drill chucks. Have quite a few. Almost never used them.
Max RPM for roto-brushes iis 800 for brass & steel, 2,300 for horse hair & nylon.
I travel with a 18v Makita drill driver combo kit. The two ranges on the drill work pretty well, 800 & 1,900.
When I have a few pairs to do, I usually use a Bosch 3/8" corded drill. The specs are not that different from the 18v cordless drill but in real life it works mush faster. The trigger lock button also takes a huge load off the hand.
Porter Cable sells one with a trigger lock for $40. Similar to the Dewalt drill. More than adequate for the job.
