Handyman tips-understanding the functions of an electric drill
POWER DRILLSThe electric drill is probably the most sold tool in the tool market today-and lets face it rightly so,because there ir
not a lot you can do around the home without one-for anything you want to attach to the wall you need a drill to first of all
make holes for the plugs that will hold the screws.
Basic workings are that:
when the drill is plugged in the trigger activates the motor which turns the gears like the wheel of a car,which in turn
spin the chuck holding the drillbit in the rotational diection in which the selector dial was programed-IE; forward or reverse.
some drill come with a "Hammer" function which means that it can easilly drill through concrete and hard materials much
easier than a normal drill.
When choosing a drill there are ceartain terms to look out for:
1.Hammer action-a semi pumping action like someone wearing boxing gloves and punching a wall several times with speed.
This action helps to break up brick,concrete and any hard materials.
2.Reverse action- this function allows you to remove the drillbit from a tight hole or to remove screws-a useful feature.
3.Trigger lock-this is a seperate button on the dril-when depressed it keeps the drill running continuously unti the trigger
is depressed again.
There are two basic types of drill
1.corded:uses a flex and has to be pluged into the mains
ADVANTAGE: deliveres more power for tougher jobs
DISADVANTAGE: Not flexible because you always have a long trail of wire behind you.
2.cordless:This is more widely used than the corded version
ADVANTAGE:fully mobile can be used anywhere without the need to look for an electrical outlet.
DISADVANTAGE:battery life is limited and it takes about an hour on average to charge the batteries so you always need 2 batteries
so that whilst one is charging you have another one to use whilst you are waiting .
