Power drills are great tools and can be used for various jobs besides just drilling holes. You can also use them install screws, strip paint, and even use them as sanders and polishers. The power drill is very versatile but can also be dangerous if used wrong. Here is a brief run through on how to properly use a power drill.
The first thing you need to do is make sure that you are going to have enough cord to run from the outlet to where your work needs to be done. If the power cord provided by the power drill is not long enough, you can use an extension cord to reach the rest of the way. Just make sure that the cord is not laying in or near a puddle of water. This goes without saying but a power cord laying in water could result in an electric shock that could lead to sever injury or death.
Before you plug in your new power drill, you'll need to open the chuck by using the chuck key that the drill comes with. Just slide the key into the hole and turn it counterclockwise to open it up.
With the chuck loose, you'll want to now insert the drill bit into the front of the drill. Make sure you select the right type of drill bit for your job. Some of the most common drill bits are as follows:
Twist Bit: This is your normal drill bit that allows you to drill a hole into wood, plastic, and / or a light metal.
Spade Bit: This bit does the same as a normal twist bit but can drill bigger holes more effectively.
Hole Saw: This drill is primarily used for boring large holes usually from a half inch to six inches in diameter.
Glass Bit: You can use this to bore holes in glass or certain tiles.
Screwdriver Bits: These bits are for your normal flat head or Phillips screwdriver and are used for us lazy folk who do not want to use a normal screwdriver.
There are literally thousands of more bits available to fit the many jobs you need a drill for. Be sure to find the right drill bit for your job description.
Once you have the right drill bit in place, then use the chuck key to fasten it in by turning it clockwise this time. Make sure it is nice and tight so it does not fly off when in use.
Now you can go ahead and plug in the drill and press the trigger to make sure that it is on and running. Once it's on and running, make sure to line it up precisely and hold your hand steady and firm while drilling.
Make sure to read all safety and drill precautions that come with the drill before you use it.
