2, Application for bit

In Petroleum & Gas ,Water well ,Mining and Tectonic Industries ,Oil field, Construction, Geothermal, Directional Boring, and Underground Foundation work.

2,Diamond drilling bit

diamond pdc core bits for coal mining are the new bits with the characteristics of high wear resistance, high impact resistance,

high penetration rate. After using on site, it is proved that PDC bits have advantages in high speed,deep footage, long life,

steady work, few accident, good well bore quality when sneaking in hard or soft foundation. Company independently developed

the PDC drill bits have reached more than 30 varieties of products to meet the needs of different strata.

PDC bits characteristics:

1. Uses outline optimization design, adapts in different strata.

2. Short parabolic crown, cutting force balance design structure, spiral knife wing, balance the bit force, improve

impact resistance.

3. Uses the dynamic flow field technique of simulation, optimizes the drill bit water power design, strengthens the drill bit clean, cooling capacity and prevents the drill bit balling.

4. Using high performance compound piece combination , enhances the bit life.

packaging&Shipping:

By sea,By air ,By train,By truck,and so on

1). By Express like TNT, DHL, UPS, Fedex, Aramex, suitable for small bits total weight less than 45kg

2). By Air, suitable for urgent orders, total weight exceed 45kg

3). By ship, suitable for large quantity, will take more shipping time

Our Services

How to choose the type:

shallow well, mainly consider the drilling speed and preventing the mud pack.

deep well,mainly consider the bit footage

When out of the well the outer cutter is broken heavily, should be selected with gage bit

In the ease of deviated section should use small and short cutter bit

In the selection of insert button bit, should use the wedge-shaped cutter

Diamond limestone, appropriate uses double bevel gear, projectile shape tooth bit

Shale more or drilling fluid density is larger, should be selected with a larger amount of slip drill

The formation of limestone, sandstone, should choose smaller slip bit

In drilling hard and high abrasive stratum, appropriate uses ball tooth, double cone tooth head.
