JDK’s diamond core bits provide excellent drilling performance on reinforced concrete. Precise processing and surface treatment as well as high quality segments make for better drilling. Each segment for the diamond core drill bit is made from high-grade diamond powder and sintered by an Italian Arga sintering machine. Depending on the working condition, we can customize the diamond core bit to be used for brick, soft concrete, and reinforced concrete with aggregate containing granite, marble, limestone, sandstone, and quartz.
