Because some materials are harder to drill through or they are more fragile, there are different types of drill bits that you can choose to drill through specific materials. For example, composite drill bits are used for those materials that are harder to drill through. The drill bits are designed in a certain way to withstand the toughness and the density of the composite material. Using some types of drill bits will overheat the bits and wear them out much quicker.
Therefore, composite drill bits are made out of a different material so that they do not wear out or overheat.
Composite drill bits are used on many types of materials, but they should not be used for just any project. They are somewhat more expensive than most drill bits, and so should only be used when necessary. This will ensure that they last longer. Also, keep in mind that most drill bits that come included with a drill are used for smaller daily projects. They should be replaced shortly after they are used before they damage the drill. Composite drill bits, because they are designed for tougher materials, will last much longer and will not need to be replaced for some time.
