How to use

Select the drill bit with the required diameter and insert it into a compatible hammer or rotary-percussion drill chuck. Use the hammer function for concrete and hard masonry; use rotary-only mode for softer materials if available. Start drilling at low speed to position the bit, then increase speed and apply steady pressure without forcing. Withdraw the bit periodically to clear dust and prevent overheating. Follow the drill manufacturer's safety and operating instructions.

Recommendations

Use appropriate personal protective equipment (safety glasses, dust mask, hearing protection) and secure workpieces before drilling. Match bit diameter to anchor or plug size and avoid side loads; replace bits that show excessive wear or damaged carbide tips.
