Secure the sheet metal to the drill press table using clamps to prevent it from moving during drilling. Use a center punch to mark the center of the hole to ensure the drill bit starts in the right spot. Start the drill press at a slow speed and gradually increase the speed as you drill through the metal. Use cutting fluid to lubricate the drill bit and reduce heat buildup. Finally, deburr the edges of the hole with a deburring tool to smooth out any rough edges. **
