How to measure drill bit size?
Here is how to find the correct drill bit size for yourself. You’ll need a drill bit gauge. They are made out of thin plastic or metal and measure approx. 3 x 6 inches. They are not expensive. However, you can make one yourself. Take a scrape piece of wood and starting with the smallest or the largest bit that you have and drill a hole through the wood. Then repeat with each bit going in order of size. Next take the bolt and starting with the smallest hole and working over to the first hole that the bolt will fit through. That will be the drill bit size you need. Count over the number of holes, then count over the number of bits you have (in order). Take the bit and fit it inside the hole that the bolt fits through to confirm that this is the correct bit. If it fits, this will be the bit you will use.
