A cordless drill is an electric drill which uses rechargeable batteries. Drills are primarily used for drilling circular holes in material, or for inserting screws and other threaded fasteners into material.

Drills are also available in the impact driver configuration, high-torque tools primarily used for driving screws and tightening nuts. Impact drivers can be especially useful when driving larger fasteners or driving into harder, more dense materials.

Safety Instructions

Always Wear Protective Eyewear. Avoid Baggy/Loose Clothing. Loose sleeves, jewelry and hair can be a hazard when you are operating a power drill.


Secure Your Work Piece. Insert and properly set your drill bit. Hand tighten chuck and make sure bit is spinning concentrically before tightening. Use a center punch to start holes.

Active Use

Ensure drill is set to proper rotation before beginning. Adjust the clutch according to material hardness - the lower 1 setting for driving screws or other fasteners, while the 2 setting can be used for drilling holes into your material.

Throughout operation, apply proper pressure to the drill - not excessive. Peck drill for harder materials or longer holes if necessary. and drill smaller pilot holes before attempting large holes.

Best Practices

Avoid mounting larger drill bits (over .5") on a cordless drill. The amount of torque required to spin and produce a successful hole can spin the drill out of the user's grip.
