Spiral Cuttings Flow Combined with Concave Guidance

4-Wing Spiral Concave PDC Drill Bit A four-wing spiral concave PDC drill bit designed to combine directional stability with efficient cuttings flow. Key Advantages Spiral blade channels support flushing and cuttings removal. Concave profile helps guide the bit during drilling. Four-wing layout balances cutting efficiency and stability. Recommended Applications Water well drilling Geological exploration Mining and engineering drilling Available Specifications Manufacturing range: 94–325 mm. Common international sizes within this range are listed as selectable options. OEM/ODM Customization Diameter, thread connection, cutter layout, color and packaging can be customized. Please provide the target formation, drilling method, required connection and order quantity before production.

Spiral Blade Channels

Spiral waterways support flushing and cuttings evacuation.

Concave Tracking Profile

The recessed center helps guide the bit and stabilize the cutting face.

Male and Female Connections

Connection style can be matched to the actual drill string.

Selection and Operating Guidance

Recommended when

  • The visible cutting structure matches the required drilling method.
  • The formation and flushing method can be supplied for configuration review.
  • A customized diameter or thread connection is required.

Confirm before ordering

  • Required diameter and thread connection
  • Formation hardness, abrasiveness and fracture condition
  • Rig model, drilling method, target depth and quantity

Performance depends on formation, rig parameters, flushing and operating practice. Final configuration should be confirmed by the technical team.

Fast Quote Checklist

Send diameter, thread/connection, formation description, target depth, rig model, flushing method and quantity. Photos or geological reports improve configuration accuracy.
