Drill bit sets are a most useful tool to have on hand at your home. They come in many different sized sets as well as one at a time. They come in many different sizes to drill almost any size hole you need. They are made of different materials to make them work better in different mediums. They are made in metric and standard sizes. You have lots of choices to pick what you will need the most, but having some of all of them is the best.
You can get bits that are a small as a hair, or one that will drill a four inch hole. Jewelers use the smallest bits on repair work and watches. Construction workers use the larger ones in building. The average home owner uses the ones in between those two sizes.
Different metals are used to make these bits. They are made from carbide, cobalt, titanium, steel, and diamond tipped. The kind of metal they are made of helps determine what they will drill through. The size and shape of the twists on them also helps decide this. Each type of designed twist makes it easier to drill through the particular substance it is made for.
There are bits that are made to drill through metal, any kind of metal. Most of these are made from carbide or titanium with a diamond tip. This keeps the bit from being worn down or breaking to easy. They wear and break easy because the rpm’s combined with the friction from the material they are drilling through creates a tremendous amount of heat. This causes the metal fatigue that makes for breakage and wear. The diamond tip helps lessen this effect.
Some bits are made for wood. These generally have a different type of twist that aids in the drilling of wood. Some of the larger wood drill bits have teeth and are called ‘hole saws’. These can drill a hole through a board or piece of wood for things like door knobs.
Concrete or masonry bits are made for drilling through concrete, plaster, and such as that. They are usually made from steel. The twists on these bits help go through cement easier than the twists on a wood bit would. They can also be hammer bits, to go in a hammer drill that beats while it turns to help get through the concrete faster.
The size and shape of the shanks vary as well. There are short shanks for drilling in close spaces, and long ones to reach into a space. There are hex shaped and round shaped shanks. This helps them to fit in almost any drill, electric or cordless.
Having an assortment of drill bit sets around the house can help you be prepared for any sort of hole drilling that you might need. Kept in their cases where the sizes are marked ensures that you will find the size you need quickly and easily. Keeping the different kinds marked for wood, metal, or masonry also makes your choice easier and quicker.
