How to Use a Drill Bit
The primary purpose of a drill bit is to bore holes into solid material. Bits have been designed to bore through cement, metal and wood, and specialty bits have been designed for a wide variety of tasks. A bit typically works like a gouge, digging material from the bottom of the hole and guiding it up and out. Most drill bits are designed to work best when held perpendicular to the material you are drilling into and when steady, gentle pressure is applied to the drill. Does this Spark an idea?

1
Turn the drill chuck counterclockwise to loosen the vise. Continue until the opening is just slightly larger than the the shaft of the bit. If you open it too wide, the shaft can get wedged improperly when you try to tighten it.
-
2
Slide the bit into the vise. Many bits are not designed to rest on the bottom of the chuck, so hold the bit in a position where only the shaft is in the vise.

Turn the chuck clockwise to tighten the vise around the bit. Most chucks only need to be hand-tightened firmly. Some chucks have a set of holes and a set of teeth designed to work with a chuck wrench. If this is the case for your drill, use the chuck wrench once you have hand-tightened the chuck.

4
Mark the point on the material that represents the center of the hole. Place the tip of the bit on the mark and hold the drill so the bit is perpendicular to the material.
-
5
Gently squeeze the trigger on your drill and apply steady, even pressure on the handle. Use your free hand to hold the drill steady and perpendicular.
-
6
Gradually release the pressure on the drill when you feel the resistance from the bit decrease. This means you are almost through the material and you will damage the material or the drill if you are pushing too hard.
-
7
Keep the drill going as you draw the bit out of the hole. This will clean out the hole and prevent snagging.
