Using the DeWalt DWHT58503 nail set is simple. First, pick the right tip for your job from the interchangeable ones available - 1/32 in., 2/32 in., 3/32 in. or #2 Phillips tip. Attach it to the nail setter. The hexagonal head stops it from rolling around when you put it down. Use the knurled locking collar to easily release and reverse nails. When you're using it, make sure to strike the metal edge with a hammer carefully. For maintenance, keep it clean after each use. Wipe off any dirt or debris. Store it in a dry place to prevent rust. This will help your nail set last a long time and keep working well.
