Using the Bosch HC8515 SDS - Max Rotary Hammer Core Bit is straightforward. First, make sure your rotary hammer is compatible with SDS - Max bits. Insert the bit securely into the tool. When starting to drill, use the carbide - tipped pilot drill to center the hole easily. This bit is great for vertical drilling and can create large, clean holes up to 6 inches in diameter and 4 inches deep. When using, keep the drill at a steady pace and apply consistent pressure. As for maintenance, after each use, clean the bit with a brush to remove any debris. Check the carbide tip regularly for wear and tear. If it's damaged, it may be time to replace the bit. Store the bit in a dry place to prevent rusting. That way, your Bosch HC8515 will serve you well for a long time.
