Metal-boring tools do precisely as their name says -- make holes through metallic materials. If you are a welder, then you are likely to use a hand drill to bore through metal surfaces. Metal sculptors and mechanics are more likely to use drill presses to make their hole-boring process more effective. You can use either a manual or an electric drill to bore through metal.
People dig holes for many reasons -- for erecting poles, making fences or building a house. A clamshell posthole digger is a tool you can use to bore small holes at calculated lengths in a compound. An auger is another tool for making holes in the ground. Auger holes are larger compared to posthole digger holes. The two types of augers are the vehicle-mounted auger and the gas-powered auger.
A nail is the most common type of tool for boring wood. However, that also requires a hammer. Another tool for boring wood is the hand drill. The drills contain a large bit, which is threaded. Chisels are other tools carpenters use to bore wood when making decorations on pieces of furniture or wood sculptures.
Leather is bored during drying, designing a product or repairing. When boring leather, you will need tools such as a leather punch, if you need to make small holes on a piece. You can also use a leather lathe to make a large hole on the leather material. Other tools you can use to bore leather include the awl and the hammered leather awl.
