what PDC bits should i use

PDC BIT OPTIONS:

Body:

Steel body PDC bits are a lower cost alternative, to matrix body bits. They are generally preferred in soft formations, such as sandstone.

Matrix body PDC bits provide excellent resistance to wear. They are commonly used in harder more abrasive formations such as limestone and dolomite.

Number of Blades:

The number of blades on a PDC bit is largely determined by the formation being drilled.

Generally higher blade and cutter counts are used for harder formations, whereas in softer formations fewer blades can be used to increase ROP.

Gauge protections is applied to all bit blades to insure longevity and to sustain a straighter hole which increases ROP.

Cutter Characteristics (count and size):

Cutter count and size can be adjusted for drilling in specifi c formations. Small cutters and high cutter count are chosen for hard and abrasive rock formations,

whereas large cutters and a reduced cutter count are preferred for soft to medium formations.

Hydraulics:

PDC bits are available with flushing holes or open center and either fixed or adjustable nozzles.

Options are available for all varieties of PDC bits and are designed specific to those PDC bits to maximize bit performance and longevity

Champion New PDC bit

large circulation ports on the side of the bit instead of the bottom to reduce plugging in softer formations. bore through sandstone, limestone, granite, conglomerate, basalt, shale and any other hard substance that may impede us.
One Piece Steel Body PDC bits

These bits are recommended for drilling in soft to medium, sedimentary formations Mainly used for geological exploration,coal mining, water conservancy and hydropower, construction of road, railway, bridge and building.
PDC cutter

PCD or PDC cutter is a material composed by diamond and carbide matrix composite with high hardness, wear resistance characteristics, widely used in oil drilling, geological exploration, coal drilling bits and machining tools ,etc.
Anchor drill bits

Mainly used in drilling anchor nets support holes in coalfields, in mines for drilling holes for roof-bolts, providing a powerful guarantee for efficient roadway excavation.
