I use the tdk12 to install ski bindings as in about 3000 pair since i've purchased it i like it alot, i honestly don't understand the brushless thing if someone would care to explain it i'd appreciate it. i used it today from nine a.m. til 7 p.m. had to change the battery once, granted i wasn't using it non-stop, almost tho, had a few tune-ups to do. i guess my point is i'd say it's a great drill and if they in fact discontinue it you may get a bargain. happy holidays. dan
