These bits are used to drill low compressive strength, very soft formations.
1) The bits maximize the use of both conical and chisel inserts of large diameters and high projection.
2) This cutting structure design, combined with maximum cone offset, results in high bit penetration rates.
3) The deep intermesh of cutter rows prevents bit balling in sticky formations.
Size Available:
From 3 7/8"(98.4mm) to 26"(660.4mm).
NOTE:
Sizes and types that are not shown above can be customized according to specific drilling requirements.
