Using these DTS brazed core bits is easy. First, make sure you have the right drill for the job. Attach the bit to the drill securely, following the drill's instructions. Mark the spot where you want to drill on the material. Start the drill at a slow speed to get the bit in place, then gradually increase the speed for faster cutting. When drilling, apply steady pressure but don't push too hard. Always wear safety goggles to protect your eyes from debris. After use, clean the bit with a brush to remove any dust or debris. Store the bits in a dry place to prevent rusting. If the bit becomes dull, it might be time to replace it.
