carbide drill bits drill bits Introduction and installation

  Carbide drill bits, drill bits When the digging operation, the drill bit rotation around the vertical axis, while for axial movement. The soil is cutting torque and axial force at the core drill bits 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.
  In drilling in concrete, etc., can ease the situation suddenly changed drilling status, so that drilling operations stable, even when a large grain chips, reduced drilling efficiency is not caused by the Drilling Tools . Its axial direction by the rotation movement and the operation of the impact of the cutting operation of the composite.  Carbide drill bits installation Drill slowly lifting the box, the four legs of the box corresponding drill holes into four turntable rig, according to the choice of the appropriate size carbide drill bits core drill box, lifting the drill core box drill 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.
