Drag bits also named blade bits, with PDC cutter inserts on the blades, they are applied to rock formation f≤6,like mudstone, shale, sandstone, etc., mainly used for drain hole, grouting hole, geological and hydrology drilling,etc.

Usually drag bits are three wings, while sometime people need four wings , five wings or six wings.

Our drag bits selected high quality PDC cutters, which ensure the bits have high abrasion resistance, fast drilling speed and long life.

Our diameter is from75mm to 270mm, any special design is available upon customers' requestment.

PDC core bits incorporating PDC(Polycrystalline Diamond Compact) cutters can be very cost effective and very productive, which are applied to rock formations of f≤10,mainly used for geological and  hydrology drilling.

We have two main types of core bits are available: rib core bits and flat core bits.

The rib core bits are applied to rock formation of f≤6, like mudstone, sandstone, etc. And the flat core bits are applied to rock formations of f≤10,like limestone, granite, etc.

Our core bits adopt 2 cutters, flat and dome-shaped cutters ,

The flat cutters have high abrasion resistance and fast drilling efficiency, suitable for drilling integrate formation.

The dome-shaped cutters have high impact resistance and stable drilling performance, suitable for formations with hard interbed layers.
