Is it acceptable for construction or blue collar jobs?
In my opinion, yes. But it depends on what you are doing. If all you are doing is installing shutters (like the nice wooden ones we got from Costco) then no. Just a normal 9V/7.2V will do. This may be too powerful for such a fragile item and it’s better to play it safe if you do not have well developed fine motor skills. For normal construction jobs and house repair it is great. Just be careful to lower the clutch settings for screws and other fragile objects. If you are drilling through concrete or dense wood for a living then I recommend a more powerful corded drill (although they do have an 18V hammer version.) Yes it could probably do it but I do not recommend it because there are much better drills out there for that sort of thing. Note, this is from some one that does not do construction and does minimal home repairs. I have some experience but no where near enough to call myself an authority on the matter. The battery system. This system is awesome. You use big battery packs
