As we are relocating and going on a trip across the country to find a new home, our items are in stock. Aside from that, I bring my 20v power tools with me in case we need to fix anything along the way. Instead of carrying a huge set of drill bits, I decided to bring some step drill bits with me. They work very well, they have many sizes to choose from, they are very sharp and strong whether you are drilling wood or mild steel, of course when drilling steel I pre-drill with a regular drill before using a step drill. I used them to drill a feed hole for our new two burner stove which feeds the stove with propane using a black pipe. They worked great.
