Crushed tungsten carbide held in a nickel bronze matrix. The1720164314879518.png

3 mm grain size ensures greater concentration of carbide

which is ideal for soft formation drilling.

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

1720164372933519.pngTungsten carbide inserts set in a powder spray deposit ideal

for abrasive formations. 97% bonding guaranteed, certified by

ultrasonic report. Recommended for non- magnetic stabilizers.

HF 4000

1720164389323676.pngTungsten 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.

This oxy-acetylene process applies tough molten carbide particles of varying sizes held in a nickel chrome matrix which provides excellent bonding properties and greater surface ear characteristics are achieved. Surface hardness levels over 40 HRC. Idear for GEO-THERMAL applications over 350°
