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. Drill Pilot Holes or use center punch to start holes. Use a Drill Stand if necessary. Properly Set the Drill Bit - hand tighten chuck and make sure drill is spinning concentrically before tightening with chuck key.

Active Use

Apply Proper Pressure to the Drill - not excessive. Peck drill if necessary. Drill only in a perpendicular direction to the materiel being perforated. Adjust the clutch according to material hardness. Never use drill bits to purposely elongate holes.

Clean Up

Sweep/vacuum any debris and clean/deburr any holes and put away drill bits & countersinks that were used.

Best Practices

Depending on the diameter of the drill and the hardness of the material being drilled it may be necessary to adjust the rpms of the spindle. Typically it is not good practice to mount larger drill bits (over .5") on a cordless drill. The amount of torque required to spin and produce the hole can sprain the user's wrist.
