Core Drills
Diamond Drill Bits
Lapidary Core Drills are used to create holes in gemstone, glass, and acrylics. At Cutting Edge Supply, we have a wide variety of different sizes and styles so that you can accomplish exactly what you need.
Sintered core drills have diamond mixed throughout the entire bur which makes them last much longer and a little more expensive. Plated core drills are great for aggressive cutting and when chipping isn't a concern. Plated core drills are usually cheaper and cut quicker to begin with, however they can dull quickly.
We recommend starting with a core drill that is a smaller size than what you would like to finish with, then work up to the size you desire. This will reduce chipping and give you more control of your bur.
