Abstract

Tungsten carbide core drill bit STK are intended for core rotary and rotaryshock drilling of holes of various purpose in few and average abrasivity rocks of average hardness and firm. Application tungsten carbide core bit STK provides growth of technical and economic parameters as rotary, so rotaryshock drilling.
