Can the nail hit the wood?

Yes, but the effect will be poor. First of all, because the drill bit drilling on wood is different from the drill bit drilling on concrete; Secondly, the working principle of nail gun is different from that of electric drill. The electric drill just rotates, while the nail gun has a tapping action while rotating. So it's best not to use an electric hammer to make holes in wood. There is a specialization in the industry.

The use of expansion bolts on wood materials has never been heard of or seen. In fact, solving the problem you described is very simple. Just use an electric drill (commonly known as a pistol drill) to drill a hole, the length of which is two-thirds of the length and two-thirds of the diameter of the wooden screw in its seat. Pay attention to take out all the sawdust and install it with wood screws. For example, if you use a 6*60 wood screw, you can use a 4mm drill to drill a 40mm hole.
