Use a cordless drill-driver

Key points

• Fit the bit firmly in the chuck, and remove the battery while you change it
• Use a masonry bit for brick and block, and a wood bit for timber
• Use the clutch setting for driving screws, so you don't strip the head
• Use the drill setting for holes, and hammer mode only for masonry
• Start slowly, keep the drill straight and let the drill do the work
• Wear safety glasses, and check for pipes and cables before you drill into a wall
