Abstract:
The invention pertains to the diamond drill bit technology field, disclosing an improved diamond composite sheet drill bit for easy and rapid heat dissipation. Inside the shank, there is a heat dissipation groove with a thermal conduction component installed. Near the through-hole at the lower position inside the shank, a placement slot communicating with the through-hole is opened, and near both sides of the through-hole, first threaded holes communicating with it are also opened. The through-hole and placement slot house a drilling component, and the exterior of the shank is evenly sleeved with a protective component. The invention facilitates rapid heat conduction on the shank via the thermal conduction component, enhancing heat dissipation efficiency and preventing damage due to excessive heat. The drilling component assists in penetrating the rock, reducing wear on the diamond composite sheet from direct contact with the rock, and together, they increase drilling efficiency into the rock.
