While these bits tend to be more expensive than standard masonry options, their performance and resistance to wear make them a worthwhile investment for professionals and serious DIYers working on granite projects.

On the downside, some bits may require careful handling to avoid chipping or overheating during prolonged use. Overall, those seeking to drill into granite will benefit from selecting a high-quality drill bit designed specifically for such tough materials, ensuring accuracy and reducing the risk of damage to both the tool and the stone.
