Lapidary Diamond Core Drill Bits/Stock Sizes | Gunther Diamond Tools
Our diamond core drill bits are the best in the World. They are similar in function to a sintered drill bit, where the diamonds are completely interspersed throughout the metal, but our proprietary production process produces a stronger bit with a longer life span. Most sintered bits are produced by melting diamonds and metal power together. Our manufacturing process pulls the metal over a diamond matrix, which results in a higher concentration of diamond for superior cutting power.
Additionally, each bit is grinded between peaks to allow for a smaller abrasion area with high rotation precision. Our drill bits can yield 500 to 800 holes per bit. When combined with our cooling and the self-centering systems you have a fast and precise drilling tool.
We try to keep these standard sizes in stock and often can ship within a few days HOWEVER it can take as long as 2-4 week, if our inventory is depleted.
If you need a size not listed here, please see the Custom Size Drill Bits option.
**Don't forget the Counter Part. Counter parts are sold separately because they will outlast drill bits and can be used over and over again. If this is the first time you are purchasing a new drill bit size you will need to purchase the same size Counter Part for the self centering system. Here is a link to the Stock Size Counter Parts.
