ImpregnatedDiamond Core Drill Bit

Features
a) The impregnated diamond coredrill bit significantly outperforms the successful series range inboth drilling speed and bit life;

b) Protects the diamond from oxidation and surface degradation duringmanufacturing;

c)  Inhibits the premature “pull- out” of the diamond;

d)  Increases the number of cutting edges exposedto the rock;

e)  Our impregnated diamond core drill bit isavailable in multiple standard configurations and selected on the basis ofrelative rock hardness and ground condition;

f)  Triple-tube bits are used with Boart Longyeartriple-tube core barrels.  The design ofthe face discharge waterways and core lifter case forces the drilling fluid tothe bit face.  The core can be recoveredand inspected in a virtually undisturbed condition;

CHINA DRILLING offers the most acceptable range ofimpregnated bit matrices.  Long respectedas the industry standard, our series matrix range provides an easy to selectand dependable foundation for your drilling needs.

When available, China Drillingimpregnated diamond core drill bit can be ordered in abrasive, standard andcompetent formulations.

Abrasive drill bits are forbroken, abrasive drilling conditions or for harder rock with broken, abrasivecondition.

Competent bits are free-cuttingfor fast penetration in very hard, competent rock or for use on lower-poweredrigs and in geo-technical applications.
