Marble Drill Bits
Diamond Tool Store stocks the highest-quality core bits for marble and other soft stones like porcelain, tile, and glass. Most marble drill bits in our inventory come with a standard 5/8"-11 thread. However, we do offer marble drill bits with other thread sizes, depending on your needs.
Additionally, we care drill shaft extensions that can be attached to your drill for deeper boring into marble. For these particular applications, we recommend a marble drill bit with brazed side protection for a smoother, cleaner hole.
Our drill bits for marble have a high concentration of diamonds for long lasting quality and performance. If you're unsure of which marble drill bit is right for you, contact one of our marble drilling experts today!
