Mark the drilling position, secure the workpiece or ensure stable wall support, and start drilling at low speed to establish the cut. Increase speed and apply steady, even pressure while keeping the bit cool if drilling in dense materials; use appropriate drilling fluid or intermittent drilling to avoid overheating. Clear debris through the discharge holes as needed and finish the hole to the required depth.
