It might sound weird to drill a hole on your hotdog bun instead of cutting it in half. Why drill? Becuase now you can add lots of condiments without worrying about spilling everything in your shirt or seeing the sausages/brats slipping away from your hotdog.
Seriously! A Leakproof hot dog! How good is that! Just twist the bun drill bit into the side of the bun to make the hole, add condiments of your choice, and slide a hot dog right in. Now you can enjoy without worrying about spills and look like a culinary genius to curious others at the same time.
