This is an appeal to the true tool-geeks out there!
One of the unsung qualities of a brushless motor drill is its high torque and ultra long battery life at very low speeds. For a demonstration, see about 6 minutes in here: https://www.youtube.com/watch?v=tPiaduBZHRU
in addition to the auto shut-off bug discussed in the video, the lowest speeds of various drills vary a lot, as does how they react to a load at low speed (or maybe at any speed). Some have lowest speeds as low as about 15 RPM, and some lowest speeds as high as 60 RPM. Some are almost unaffected by the kind of hand torque shown in the video, and others slow down considerably. Some have a very, very low speed with almost no torque.
They also all have discreet speeds as they ramp their way up --not a gradual increase, but jumps. The size of these jumps also varies considerably from model to model, so some are better than others if you're looking to dial in a particular speed in the low speed range.
I'm trying to find the best drill on the market for the purpose of powering a slow speed device requiring significant torque. I've tested quite a few, but I'm wondering if people out there would be willing to test for the lowest speed on their drill and report back about it here. It's possible to do this with a small hand screw or other clamp, or even by carefully holding down the trigger lightly by hand. The best device for finding this is something that can actually be useful for certain jobs, allowing easy use of the drill at a fixed speed other than full blast: https://www.youtube.com/watch?v=oCbRWaz2Fsw With a little care with the swiveling geometry, it's possible to build such a "switch" such that it doesn't have to fall off to reach an "off" position, so one can turn the drill on and off by simply swiveling, allowing the set speed to be returned to. The other tests that I'm interested in is whether the drill slows appreciably under minor load (like that applied by hand to the spinning chuck), and whether it has the auto shut-off "feature" at about five minutes.
I'm particularly interested in ones I haven't laid my hands on: 18 Volt Bosch brushless motor drill, which is quite costly, the Worx, Dewalt Atomic, and the super cheap ones sold on Amazon as Cacoop, but the manufacturers change model numbers frequently,(and for all I know could change even within a model number) and this is a spec that isn't mentioned in any product literature, so any report back about this on any brushless motor drill would be appreciated. The manufacturers have been unwilling to give me this information when I've written and asked.
Thanks!
