Product Description
114-117,
Soft Formation Tooth Bits
The 114-117 bits are used to drill low-compressive strength, soft formation. Long
projection tooth lengths are used on high offset cones to
provide the greatest penetration rates possible. Wear-resistant hard facing is used to
control tooth wear. On the softest bits type this hard facing
completely covers the bit teeth.
127
Medium-Hard Formation Tooth Bits
The 127 bits are used to drill high-compressive strength, medium hard formations. Short
projection teeth with reduced crest length
are used in this series of bit designs. Durable hard facing is applied to reduce tooth
wear.
437
Soft Formation TCI Tricone Bits
The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits
maximize
the use of both conical and chisel tungsten carbide inserts of large diameters and high
projection.
This cutting structure design, combined with maximum cone offset, result in high bit
penetratione
rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
