Yes, this thing is a baseboard nailing machine. Really, just about any type of trim work is the intended use.
If it is a Dewalt 20volt grease gun then yes
Brad nails have little to no head on them, so it will do nothing for metal roofing. Not to mention they are so thin (18g) they will have a hard time piercing metal without deforming. So that's a big no. As for molding/trim, it works great, that is what it is designed for.
I don't think this nailer uses a belt. If it does, any and all replacement parts for any dewalt tool are available through their online ServiceNet portal. Look up your tool model number and it will give you an exploded diagram of every part/component. Find your part and order it.
If it is a 20volt trimmer then yes
6 pounds. If you are concerned about holding it, my wife who is 5'3" and weighs 125 lbs can use it easily.
Jackie, you mean the options 1) Store Pickup, 2) Ship to Home, or 3) Delivery??? None of those apply to you? How else is there to buy a tool? You either buy it at a store, or have it delivered. Also, you can buy it anywhere, you don't need to buy it at HD exclusively. You have thousands of options to buy it.
Yes it will work just as good if not better than pneumatic nail guns of the same caliber
No it’s an 18 gauge gun!!!!! If you want 16 gauge you have to buy a 16 gauge gun!!!!
