GUSHI core drilling bits profiles and work process

Core drilling bits, are used to drill 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. Used or other masonry materials drilling in stone, or used to drill holes explode.Core drilling bits work process: When digging operations, drill 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 centrifugal force to work loose leaf and stir core drilling bit , 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. Choose the appropriate drill core drill according to the specifications of the box, lifting the drill bit into the drill core boxes will be installed inside the box and then the corresponding convex tip drill core box Drilling Tools  and the core drilling bits, will drill into the box carbide drill bits, drill that card on the turntable heart. Then turn on the drill spin coupling nut drill pipe. When in use, remove the drill should be attached to the spindle collet that header from packing boxes or automatic replacement drill tool library. Then run back into packing boxes. To settle with the grinding wheel surface edge. Before grinding core drilling bits,, drill bit first to the main cutting edge and the wheel surface is placed in a horizontal plane, that is, to ensure that when the blade contacts the wheel surface, the entire blade must grind to. This is the first core drilling bits, relative position of the grinding wheel, and then slowly to gracefully position on the surface of the grinding wheel.
