Tungsten Carbide Drill

    A bit used in core drilling. Steel cylinder of bit body on because of welding tungsten carbide carbide cutting tools. The shapes of the tungsten carbide cutting tools and its welding on the bit number, arrangement, welding Angle different, referred to as the bottom blade, the blade and blade, going out to ensure that the periods of water and powder.
    Bit body the upper part of the core tube is threaded connections, bit body side open tank, also opened a nozzle lip at the bottom of the surface. Tank and nozzle are guarantee the circulation of flushing fluid, can play a bit role to eliminate rock dust and cooling. Drilling clay layer and shale strata, in order to increase the clearance on the internal and external wall of hard alloy bit welding frame, frame type drill bit.
    In hard strata with high abrasive can use needle-like carbide sharpening drill bits. General of hard alloy bit drilling rock drillability Ⅱ formation of a Ⅶ level; Needle-like carbide drill rock drilling Ⅵ - Ⅷ level.
    When choosing tungsten carbide drill, you first need to consider the size of the drilling machining accuracy requirement.
