Milled Steel Teeth Tricone Bits 15inch IADC127

Tricone Bits with Steel Milled Teeth 15'' IADC Code 127 , Rock drilling tools manufacturer ROSCHEN offers a complete line of rotary drilling tools. These bits are designed with smaller teeth, which are more closely arranged together. Drill speeds are higher when the rock face is harder and TCI can withstand the heat generated from these conditions. Mud is pumped down the drill string and out through the tricone bit to keep the bit clean from cuttings and to move these cuttings back to the surface.

Product Description

Milled Steel Teeth Tricone Bits 15inch IADC127


Product description: 

Mill tooth tricone bits are used in soft rock formations. The protruding teeth are widely spaced to prevent getting clogged with material as they cut through the surface material. Tungsten carbide insert (TCI) tricone bits are used for medium and hard rock formations. Rock drilling tools manufacturer ROSCHEN offers a complete line of rotary drilling tools.  These bits are designed with smaller teeth, which are more closely arranged together. Drill speeds are higher when the rock face is harder and TCI can withstand the heat generated from these conditions. Mud is pumped down the drill string and out through the tricone bit to keep the bit clean from cuttings and to move these cuttings back to the surface.
