The brad nailer was introduced after the finish nailer primarily to provide a gun that shoots thinner nails.
You will find that brad nailers are designed for 18 gauge nails.
You’ll want to use a brad nailer on the smaller applications where you are worried about splitting the wood or the size of the nail head.
As any nail head will leave a hole in the wood, you’ll obviously want a nail that won’t leave too big of a hole – and that’s what the brad nailer is for. An 18 gauge brad nailer will have a reduced hole size which leaves less of a mark in your woodwork. Depending on the material you’re using, you may not even need to fill it in before painting.
Brad nailers are used for on wood where splitting might be an issue or where you would want a thinner nail for less of a hole. They have many uses but they are most commonly used for:
Fastening decorative molding
Ideal for thin or more delicate wood that you’re worried about splitting
Leaves small nail head holes
Brads can be used to temporarily hold things in place when using glue. Simply remove them when the glue has dried and the nail holes are barely visible.
The nails are perfect for small projects, like making jewelry boxes, picture frames, or attaching decorating trims and edges to cabinetry.
