do some house work,you may end up needing a power drill.A power drill is a drill that you do not have to use good old fashion elbow grease with.The old drills back in the day did not have power running through them.To drill a hole in something you would have had to get it going by hand.Although these types of drills still work,they take a lot more time to use.Not only that,but over time it's going to wear you out a lot faster than the power drills of today.So what does a power drill do?The word drill actually comes form a Dutch word that is called Drillen.A power drill is a tool that has a drill bit on the end of it.The drill then spins this drill bit around very fast,and it digs a hole into different surfaces.Most of the time,you will see power drills being used in woodworking and of course,metalworking.Although the drill itself can be big,the drill bit is what is doing all the work.You sill notice that the motor is in the body of the drill,but this is just used to spin the shaft that the drill bit is on.The bit is the tool that actually cuts into the target material.Without the drill bit,you would just have a round shaft that spins without a purpose.There are tons of different types of drill bits that you can put on the end of your power drill.These drill bits are used to drill into different things.Some of them are made to drill into wood,and others are used to drill right through metal.Other drill bits can go through rock and even concrete.It's important to make sure that you use the right drill bit for every job.Otherwise,you could end up damaging the drill or the drill bit itself.
