HF1000
Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for drilling soft formation.
HF2000
Trapezoidal tungsten carbide inserts held in
a sintered carbide nickel bronze matrix. This will give a great depth of
carbide coverage-ideal for high deviation drilling in abrasive formations.
HF3000
Tungsten carbide inserts sets in a powder
spray deposit ideal for abrasive formations.97% bonding guaranteed, certified
by ultrasonic reports. This kind is recommended for non-magnetic stabilizer.
HF4000
Tungsten carbide inserts (button type), The
inserts have been developed to allow cold insertion and maintain close fit. A
great concentration of inserts on the bottom third of the blade and leading
edge will increase surface contact to reduce wear in highly abrasive
formations.
HF5000
This oxy-acetylene process applies tough
molten carbide particles of varying sizes held in a nickel chrome matrix which
provided excellent bonding properties and greater surface wear characteristics
are achieved. Surface hardness levels over 40HRC.Ideal for geo-thermal
applications over 350°C.
