you are correct in this aspect...
you are correct in this aspect...Doesn't really work, Tom...snow, heat, cold, rain, wind, ice on the driveway, longer hoses, extension cord, etc...
Besides, the fine dust gets all over the place (driveway, lawn, cars, neighbors, etc) and then gets tracked into the house.
Bought one a long time ago and now I use it to blow off the driveway...the bag made good compost...
Robert the most efficient dust collection will happen as close as possible to the source so using the dust ports on those tools is your best plan of attack especially for the portable ones. The bag units are basically dust redistributors and not dust collectors unless you spend a bunch of money on replacing the top bag with a cartridge filter. All they do is catch the large particles. The fine dust goes right through them. I know this because that's what mine does and Tom's suggestion to wheel it outside doesn't work for all of us. It's too cold in the winter to do that here. I would definitely have no faith in the small single bag ones to work.
A drill press doesn't make much fine dust but if you want DC at it then maybe this Lee Valley magnetic dust chute is your answer. It might be for a band saw too if you can find or make a mounting spot for it. https://www.leevalley.com/en-us/sho...accessories/30041-veritas-magnetic-dust-chute
