We know that there are a lot of other companies out there producing core bits, that's why when we started producing diamond tools we worked with the some of the brightest minds in manufacturing and tooling, as well as fellow tradesmen to find out how we could make better tools. We're confident that we have done just that and here are a few reasons why:


All our tools are produced with the most advanced manufacturing processes available and use the highest-grade synthetic diamonds and metal bonding powders available in the industry. Producing a core bit that is built to last through the toughest jobs and give you a longer lasting product.


A lot of companies will lead you to believe that a “drill is just a drill” or a “diamond blade is just a blade”, getting you to invest in products that you constantly have to replace. We don’t believe that. The team at Carbon Diamond Abrasives have created core bits that have a truly unique segmented design, and that you won’t find with other companies. This innovative design means that the equipment you buy from us is designed with the work your taking on in mind.


When it comes to the production of our diamond tools, we make sure that they are as easy to use, safe, and that they use the most up to date technology. All of our blades and core bits are imbedded with our multilayered dry diamond dispersion technology, that creates blades that cut precise.


At Carbon, we understand the difficulty that can come with finding high quality core bits that will last. Which is why when we started producing diamond tools, our team went all in on design, quality, and R&D.

We don’t sit in an office every day talking about drilling with diamond tools. We’re out in the field using the very diamond core bits we produce. Which has created a diamond tool company that is constantly raising the bar for better tools for our industry.

Everyone single diamond tool we’ve manufactured has been constructed with the most up to date technologies available in the diamond tool industries, and with feedback from fellow industry professionals. This formula has provided us with diamond products that are truly the best out there.
We’ve spent hundreds of hours on our research and development over 10+ years. Everything from our core bit drill sets to our hand held drills have gone through extensive quality control test both in our factories and in the field, to ensure that they are built to take on the toughest jobs.
