Power Drill

A power drill is a handheld tool that uses a rotating bit to make holes in various materials or drive fasteners into place. Drills come in several varieties

• Variable Speed Driver - The most common type, the chuck rotates at higher or lower speed depending on trigger pressure.

• Impact Driver - Uses a spinning hammer and anvil inside the drill to knock the chuck in a rotating motion. Impact drivers can loosen fasteners easier and tighten them further. When used in the wrong application, overtightening can damage wood.

• Hammer Drill - The rotating chuck also hammers forward and back for added impact. This motion also helps to clear material when drilling into concrete or cement.

Prepare Before Use

• Choose the right drill bit for the job.

  • Driver bits are available for any screw, bolt or fastener

  • Spiral shank are best for making pilot holes

  • Spade tip bits can drill holes through any thickness at a 90 degree angle

  • Hole Saws are cleaner and can be easier on your wrist, but are limited by their depth

• Fit the bit into the chuck at the tip of the drill and tighten it securely.

  • Most corded drills have a chuck key which fits into the teeth of the chuck for added tightening strength.

Tool Tips

• Hold the drill firmly and apply pressure to the bit as you drill into the material.
