Updated: 8 December 2025

Power drills are among the most commonly used tools across construction, metalwork, woodworking and DIY projects.

Proper Oiling

Power drills contain several moving parts that rely on adequate lubrication. Always refer to the user manual to determine the correct oil type and lubrication points. Proper lubrication reduces friction, prevents overheating and keeps the motor running smoothly.

Keep Drill Bits Sharp

Dull, chipped or worn drill bits force the tool to work harder and compromise accuracy. When drilling into hard materials such as concrete, replace worn bits regularly. Sharp drill bits improve performance, reduce strain on the motor and produce clean, precise holes.

Check the Power Cord

For corded drills, inspect the power cord frequently for kinks, cracks or breaks. Damaged cords can interrupt electrical flow, overload the motor or create dangerous shock hazards. Replace compromised cords immediately to protect both the tool and the operator.

Care for Drill Bits

Never store drill bits while still attached to the power drill. Remove and place them back into their protective cases to prevent damage, reduce wear and avoid misplacement. Keeping bits organised ensures they remain sharp, safe and ready for the next job.
