Step 1: Idea
Even though I am just thirteen my dad died when I was five so I am always having to do odd jobs around the house. I have a large amount of tools which belonged to my dad. I keep having trouble where when I drill through some wood there is a circle where the drill bit has gone through and the silver bit that attaches the drill bit to the drill.
Step 2: The Parts
You will need - a cordless drill - a drill bit - and an old golf ball
Step 3: Assembly
Find an old golf ball and cut it in half. Then remove the outer shell. The problem with this design is that you need a different bit of golf ball for each drill bit you use (you only really need one for the smaller drill bits) use the drill bit you need to. Then place the part over the end. And your done :)
