Components:

• Chuck: The part that holds the drill bit or screwdriver bit. Can be keyless (for quick bit changes) or keyed (requiring a chuck key for bit changes).
• Trigger: The control used to start and stop the drill, often pressure-sensitive to control the speed.
• Grip/Handle: Ergonomically designed for comfortable use, often with rubberized material for better grip.
• Motor: Powers the drill bit, with different power ratings typically measured in amps (corded) or volts (cordless).
• Battery (for cordless): Rechargeable lithium-ion batteries are common, known for their long life and quick charging times.
