Development of low temperature electroplated hot-pressed diamond impregnated drill bits
Abstract The hot-pressed diamond impregnated drill bit is produced by low-temperature electroplating process (room temperature), or the diamond impregnated insert is mounted on the rigid body of the drill, and then a diamond composite coating is coated on the surface to bond it with the rigid body to avoid it. Silver welding has secondary thermal damage to the diamond, and the drill has the advantages of good adjustability of the carcass performance and strong internal and external diameter. Praised by production users.
