Push Drills and Electric Drills - How to Use Them
A push drill is an excellent tool for starting screws and drilling small holes.
It looks a little like a screwdriver and is held the same way.
It comes with a set of special bits that are usually carried in a compartment in the handle.
The bits are notched and snap into the chuck.
The chuck is the mechanism that grips the bit.
To insert a bit, pull the spring-loaded chuck back toward the handle (in some models, away from the handle), slip in a bit, and let the chuck snap back.
Usually, the bit must be rotated until a click is heard.
That means it is seated in the chuck.
A push drill is operated much like a ratchet screwdriver.
Hold the handle as you would a screwdriver.
Place the bit against the wood and move your hand up and down, keeping the bit in contact with the wood.
As you push your hand down, the bit drills into the wood.
An electric drill is the least-expensive power tool you can buy.
A drill with one forward speed can be purchased for ten to twenty dollars.
However, if you are going to invest in a drill, I recommend a 3/8-inch, variable-speed drill with forward and reverse.
The 3/8 inch refers to the chuck, which will accept bits that are up to 3/8 inch in diameter.
Variable-speed drills allow you to vary the rotating speed of the bit by changing the amount of pressure on the trigger.
This is useful when using the drill as a screwdriver.
Most drills are double insulated.
The motor is surrounded by a material that won't conduct electricity, so if a wire comes loose inside the drill, you won't get shocked.
The bits are locked into the chuck with a chuck key.
The tip of the chuck key is inserted into one of the three holes located around the chuck.
When it is rotated clockwise, the slots in the key mesh with the slots around the chuck and the jaws of the chuck close around the bit.
To remove the bit, turn the chuck key counterclockwise.
When drilling, hold the drill in your strong hand.
I like to put my first finger along the housing and operate the trigger with my middle finger.
This grip affords more control to those of us with small hands.
Hold the drill perpendicular to the wood.
When the bit begins to rotate, there is a tendency for the drill bit to slip off the mark.
To prevent this, make a small indentation on the mark with a nail or nail set.
Push the drill into the wood with even pressure.
When you have reached the appropriate depth, pull the drill straight up, keeping your finger on the trigger.
The rotation of the bit removes shavings from the hole and makes removing the bit easier.
After the drill is clear of the wood, release the trigger.
