PDC NON-CORE BIT SERIES

PDC Non-Core Bit Series

Non-core drilling tools selected by structure, flushing path, waterway design, and formation conditions for gas drainage, water detection, and related mining applications.

Flat-Top Bit

Engineering Advantages

  1. 01SHAPED FLAT-TOP CROWN
  2. 02CONTROLLED DIRECTIONAL GUIDANCE
  3. 03CONTINUOUS BORE CLEANING

Formation / Operating Conditions
f ≤ 10
Size Range
Φ56–Φ120 mm

Product Details

The flat-top crown and cutter arrangement are configured for directional drilling where guidance, bore-path control, and stable engagement are important. Its compact steel-body profile supports consistent cutting response and effective flushing while allowing connection and cutter details to be matched to the drilling assembly.

Drag Bit

Engineering Advantages

  1. 01SHARP CUTTING EDGES
  2. 02FAST PENETRATION
  3. 03RELIABLE FLUSHING

Formation / Operating Conditions
f ≤ 10
Size Range
Φ75–Φ311 mm

Product Details

The drag-bit structure uses conical or stepped blades to form sharp cutting edges while preserving open space for cuttings removal. It is suited to soft, uniform formations where rapid penetration, straightforward torque response, and reliable bore cleaning are favored over complex cutting geometry.

Model-to-Formation Match

Match each non-core bit configuration to formation category and Protodyakonov coefficient F before final connection and diameter selection.
