These short diamond core drill bits feature crown segments and a circle of vacuum-brazed diamonds on the outside of the barrel. The crown segments provide a longer lifespan. They can be used for drilling granite, marble, concrete, reinforced concrete, and other stones. The vacuum-brazed diamonds on the outside help protect the barrel, enhance cutting speed, and improve drilling ability. They can be used for both wet and dry drilling.
We offer a series of 60mm length dry-use diamond core drill bits, with diameters ranging from 25mm to 110mm. Two types of vacuum-brazed diamonds are available: strip type and dot type. Connection types include round shank, G 1/2″, 5/8″-11, and M14. Segment types available include crown, turbo, roof, and more.
