PDC Non-core Bits

This series of non-core PDC bits is designed for coal mining, geological exploration, gasdrainage, and tunneling. They provide efficient drilling and stable borehole quality across a wide range of formations.

Concave Bit

The concave crown with flat wings enables smooth start/re-entry and efficient cuttings transport, ideal for homogeneous soft to medium-hard foramtions and short/medium runs.

Applicable Formations

F ≤ 10

Size Range (mm)

Φ48 – Φ153

Three-Wing Flat

Five-Wing Flat

Four-Wing Step

Three-Wing Flat

ArcBlade Bit

Steel body offers faster drilling and better chip evacuation in medium-soft formations.

Applicable Formations

8 < F ≤ 12

Size Range (mm)

Φ75 – Φ311

Three Wing ArcBlade

Four Wing ArcBlade

Multi-Wing Flat-Top Bit

Steel body offers faster drilling and better chip evacuation in medium-soft formations.

Applicable Formations

8 < F ≤ 12

Size Range (mm)

Φ56–Φ120

Five Wing Flat-Top Bit

Four Wing Flat-Top Bit

Flat-Top Bit

Arc-shaped crown with carbide pillar structure provides excellent stability and guidance by minimizing bit oscillation during operation.

Alternating rake and orientation interleave cutting paths to reduce torque fluctuation and deviation.

Applicable Formations

8 < F ≤ 12

Size Range (mm)

Φ56 – Φ120

Drag Bit

The drag-type PDC bit uses conical or step blade geometry for sharp cutting, fast ROP, and smooth chip evacuation in soft to moderately hard formations.

Conical blade ensures sharp cutting teeth and stable drilling perfor mance.

Applicable Formations

F ≤ 6 Soft homogeneous formation

Size Range (mm)

Φ75–Φ311
