Use Proper Drill Speed and Pressure: Start drilling at a slow speed to create a pilot hole, then gradually increase to a proper speed as needed. Apply steady and even pressure; avoid excessive force which can bend or break the drill bit. 2. Cooling and Lubrication: When drilling tough materials like concrete or stone, use water or a suitable lubricant to keep the drill bit cool. Overheating can damage the temper of the bit. 3. Avoid Rebar and Hard Obstacles to avoid damaging the bit. 4. Avoid Hammer Function on Non-Impact Bits: If you have non-impact masonry drill bits, avoid using them with a hammer drill setting. This can lead to premature wear and damage to the drill bit. 5. Clean After Use: After drilling, clean your masonry drill bits with a brush to remove dust and debris. This helps maintain their cutting performance and prevents corrosion. 6. Proper Storage: Store your masonry drill bits in a secure and dry place. Avoid storing them where they can rub against each other or against hard surfaces, which can dull the cutting edges.
