Using the Bosch T3913SC is easy. First, make sure your hammer drill is compatible with SDS - Plus chuck fitment. Attach the core bit to the drill, then start drilling into masonry, brick, or block. Thanks to the ejector hole, when you're done, you can easily remove the core. When using this bit, always wear safety goggles and gloves. Keep the drill at a steady pace and don't apply too much pressure, especially when using it with smaller hammers. For maintenance, after each use, clean the bit with a brush to remove debris. Store it in a dry place to prevent rusting. This will help keep your Bosch T3913SC in good condition and ready for your next project.
