PDC drill bits for water well, mining and exploration.
FengSu PDC configurations are reviewed around the formation, hole specification, rig and operating target—not selected by diameter alone.
Core and coreless · custom geometry · OEM marking · technical selection

Heavy-Duty Mining PDC Bit
Gauge protection and cutter grade reviewed per site
Sample mining configuration emphasizing gauge protection and abrasive-wear review.
View product4-7 blade focus
Compare blade-count tendencies before selecting the detailed geometry.
Blade count does not replace a formation review. Cutter exposure, profile, gauge length, body protection and total flow area can make two bits with the same blade count behave differently.
Information for selection
Four details determine a useful PDC recommendation.
A short operating description is more valuable than a part number without context.
Formation
Rock type, hardness, integrity, abrasiveness and any interbedded layers.
Hole specification
Required diameter, target depth, inclination and core or full-face drilling.
Rig and circulation
Rig model, rotary speed, weight on bit, connection and fluid or air circulation.
Performance target
Penetration, service life, core recovery, stability or a specific operating problem.
Applications
PDC tools for established drilling applications.
Water well drilling
Water well, geothermal and large-diameter drilling in formations suitable for PDC cutting.
Mining and gas drainage
Exploration, coal mine and directional drilling where a matched PDC profile is appropriate.
Geological exploration
Core drilling and sampling configurations selected around recovery and formation conditions.
Technical reading
Prepare the details that affect compatibility.
Comparable evidence
Measured PDC results in real formations.
Review limestone, fractured volcanic rock and core-drilling records with the rig, diameter and recorded result shown together.
