Cone shaped grinding shoes are mainly used for repairing deformed fish tops or trimming burrs caused by various tools during the drilling process, such as curling and perforation at the casing joint, cleaning up mineral crystals and other hard debris trapped on the wellbore wall, in order to restore the diameter size. Piercing and conical grinding shoes rely on the alloy milling on the cone to cut the protruding inner wall of the casing and the crystals and other impurities remaining on the inner wall of the casing. The cylindrical part serves as a stabilizer, and the debris milled is carried back to the surface by the flushing fluid.
