The core drilling bits is used for drilling in solid materials with a through hole or blind hole

     In core drilling bits in concrete, etc., can ease the situation suddenly changed drilling status, so that core drilling bits operations stable, even when a large grain chips, reduced core drilling bits efficiency is not caused by the drill. Its axial direction by the rotation movement and the operation of the impact of the cutting core drilling bits  of the composite.Drill slowly lifting the box, the four legs of the box corresponding core drilling bits holes into four turntable rig, according to the choice of the appropriate size drill core drill box, lifting the drill core box core drilling bits box into the body and then to groove and drill drill core box corresponding convex tip installed, will drill into the box drill, drill that card on the turntable heart. Then turn on the drill spin coupling nut drill pipe.When the digging operation, the core drilling bits bit rotation around the Drilling Tools  axis, while for axial movement. The soil is cutting torque and axial force at the bit role, was destroyed in the extrusion and centrifugal force to work loose leaf and stir chopped, pressed to form a soil pit wall flow, while the elevator to the surface along the page. When the earth moves to free Pit stop the flow at the time, due to the centrifugal force pulverizer was thrown around the pit, complete the digging process. The core drilling bits is used for drilling in solid materials with a through hole or blind hole, and can have a hole for the reaming tool.
