  GUSHI drill bit for metal The drill is used for drilling in solid materials with a through hole or blind hole, and can have a hole for the reaming tool. Commonly used mainly twist drill, flat drill, center drill, deep hole drilling and core drill. 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 bit role, was destroyed in the extrusion and core drilling bit 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. A drilling operations conducted on concrete, Drilling Tools  state can ease the situation suddenly changed, so that drilling operations stable, even when a large grain chips, reduced drilling efficiency is not caused by the drill. Drill slowly lifting drill cartridge installed, the four legs of the box corresponding to drill four holes into the rig turntable, choose the appropriate drill core drill according to the specifications of the box, lifting the drill bit into the drill core box inside the box then drill a groove to be installed with the convex tip drill core boxes correspond to drill into the box drill, drill that card on the turntable heart.
