After minutes of pounding the nails (and my thumb >.<) I've finally hung my modem and router. :)

There are times that we, moms, have to do what "only dads can do" like drilling a hole in a concrete wall! I had to drill a hole in the wall and put the nails in order to hang my DSL modem and my router to make my workspace organized and of course, to prevent the kids from playing with the gadgets, especially the cords but I had no one to do it so i had to do it on my own. The apparatus to use in drilling a hole is the Electric Hand drill tool. I'm kinda familiar in using it so i tried to drill a hole in the concrete but the hole that i made was bigger than what i intended and i just realized that i had to replace the drill bit that is installed in the hand drill. I didn't know how to change the drill bit until i stumbled upon an instruction in the internet courtesy of Ehow so i want to share to you moms what i have learned. :)

Instructions

1. Decide which bit you will be attaching. This will depend on exactly what application you are going to be using the drill for. Do you need to screw drywall onto wall studs? Do you need to bore a hole for a door handle? Or perhaps you need to drill a pilot hole for a furniture project. Choosing the proper bit is important for making the job go smoother and easier.

2. Find the chuck key and locate the clamp gear and chuck cap. You will have to use the chuck key in order to break the drill's hold on the current bit. The chuck key is usually found attached to the cord near the plug end. It is a piece of metal featuring a thin handle and a round, grooved head that resembles a gear. On the front of the electric hand drill you will see a set of grooves that resemble those found on the chuck key; this is the clamp gear. There will also be a series of holes immediately in front of the gearlike grooves; this area is called the chuck cap.
3. Insert the tip of the chuck key into one of the holes on the chuck cap. The grooves on the chuck key and the clamp gear should fit together.

4. Turn the chuck key counter-clockwise. Use the handle of the chuck key to get proper leverage. Like the gears in a clock, the turning chuck key will force the bit slot of the drill to open. Sometimes, a little extra force is required if the existing bit was really tightened down. Once you break the hold you can easily loosen the drill tip by turning the chuck with your hand.
5. Remove the current drill bit and open the chuck wide enough for your new drill bit. With the old bit removed, you may have to open the tip up even wider depending on the size of the bit you will now be attaching. If that is the case, just keep turning the chuck to open it wider.
6. Insert the new bit and hand tighten the chuck to hold the bit in place. Use the chuck key to further tighten down the drill's hold on the bit by inserting it as you did earlier and turning it clockwise. That is all it takes to change electric hand drill bits!
