Pro tip: get a small piece of clear acrylic, drill hole then set drill bit in chuck so only 5mm sticks out through the acrylic.
You will never drill all the way through again.
You sound like i did up until a few months ago haha. I now use Hardened screw starters to pre-thread screw holes in wood, never miss again. I also have on my to order list a set of depth stop drill bits.
