HF 1000

Crushed tungsten carbide held in a nickel bronze matrix. the 3 mm grain size ensures greater concentration of carbide which is ideal for soft formation drilling.

HF 2000

Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. this will give a greater depth of carbide coverage ideal for high deviation drilling in abrasive formations.

HF 3000

Tungsten carbide inserts set in a powder spray deposit ideal for abrasive formations. 97% bonding guaranteed, certified by ultrasonic report. Recommended for non- magnetic stabilizers.

TCI

Tungsten carbide inserts (button type). the inserts have been developed to allow cold insertion and maintain close fit. A greater concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.
