The important variables that should be taken into the consideration while selecting a drill bit are, the hardness of the rock, abrasive rock, whether the rock is competent or fractured, type of drill rig, depth of drilling expected, level of drilling expected, knowledge of the area, bit range and the right waterway configuration. It is fully automated and designed specifically for the manufacture of rock drill steel. These specialist drill bits are used for drilling centreholes at two different angles, 60 degrees and90 degrees. The hammering action provided by . Distributors. Adjust drill depth into backer material to proper level, (1½ times the drill diameter, or the drill point geometry + 0.010”). Drill bit basics The drilling bit industry is changing rapidly in the areas of manufacturing technology and the use of new materials. for PDC Drill Bits SPE/IADC 23939 “First Revision to the IADC Fixed Cutter Dull Grading System” ~ 1992.
