Tips for drilling through metal using your Bosch hammer drill

• Use a center punch to mark the hole location in the workpiece before you begin drilling.
• Secure the workpiece firmly before drilling so the workpiece doesn't move.
• Begin drilling using low speed to prevent the bit from slipping.
• Use a light multi-purpose oil on the drill bit to keep the bit from overheating.
• Maintain consistent pressure and use a constant speed to drill the hole.
