A hand drill is an essential tool during most home renovations and repairs. Black & Decker manufactures many different varieties of cordless hand drills to help homeowners complete their tasks. Black & Decker manufactures drills with two different types of drill chucks. Found on older drills, the keyed chuck requires the use of a pinion key to unlock drill bits. Found on newer drill models, the keyless chuck requires no such key to unlock drill bits.
