Impregnated Diamond Bits
Hughes Christensen offers a wide selection of
impregnated bits for drilling medium to hard formations.
For hard and abrasive formations, the S279 utilizes
hot pressed segments, which are proven features for
high ROP and excellent durability. When drilling mudstones
and carbonates or formations where
hydraulics can be challenging, the advanced
S280 impregnated bit is the solution. The S280
utilizes a balanced mixture of diamond sizes
to increase the space between rock and bit.
This extra “standoff” results in better cuttings
removal and higher ROP. All Hughes Christensen
impregnated bits utilize “Super Cone” technology
for enhanced durability and balanced wear.
Natural Diamond/BallaSet Diamond Bits
Hughes Christensen offers natural and BallaSet diamond
bits in a variety of styles for both motor and
rotary drilling. Various sizes, shapes and concentrations
of cutters are used in these bits to match the
requirements of your specific application.
