6 3/4" PDC drill bit with 5 blades and 16 mm cutters, built for medium-hard to hard formations.
Deep-blade hydraulics + 5 nozzles maintain cool cutters and clean returns.
Reinforced gauge tracks true in steerable systems, lowering reaming and toolface corrections.
3-1/2" API REG pin for quick fleet compatibility across BHAs.
Recommended window: 60–300 rpm, 20–125 kN WOB.
Custom nozzles and cutter grades available for shale–limestone–dolomite sequences.

This 6 3/4" PDC rock bit translates torque into consistent, low-vibration shearing. A medium parabolic crown and heavy cutter density stabilize engagement so the driller feels steady pull—less chatter, fewer stalls—while the diamond PDC bit’s deep blades sweep fines off the face before they can heat-check cutters. Returns look uniform, pumps run smoother, and motors stay in their efficiency band. On directional sections, the armored gauge behaves like rails, holding toolface without over-steering, which protects ROP and hole quality. For B2B buyers, the outcome is practical: lower NPT from fewer unplanned trips, better footage per bit, and tighter cost/ft predictability across mixed runs.
Hydraulics with headroom: Five tuned nozzles wash the cutting structure aggressively without starving the motor, improving cooling and cuttings transport at higher ROP.
16 mm cutters, balanced layout: The attack angle and spacing minimize stick-slip and cutter spall, useful on interbedded limestone–sandstone.
Reinforced gauge: Hard-wear surfaces and inserts preserve OD in abrasive streaks, sustaining steerability late in the run.
Parabolic crown geometry: Bites early yet resists tracking; helps hold trajectory through laminated shale and hard stringers.
API-standard connectivity: 3-1/2" API REG simplifies inventory and rig-up; fewer adapters, faster spud-in.
Configurable by geology: Jetted/flow tuning and cutter grade options align with your mud program and rig hydraulics.
| Parameter | Value |
|---|---|
| Bit size | 6 3/4" |
| Blades | 5 |
| Primary cutter | 16 mm |
| Nozzles | 5 |
| Connection | 3-1/2" API REG |
| RPM window | 60–300 |
| WOB window (kN) | 20–125 |
| Target formations | Hard shale, limestone, sandstone, dolomite, hard gypsum, marble |
Applications & formations: Optimized for water-well, HDD, O\&G workovers, and geothermal where intervals swing from abrasive shale to compact limestone. Heavy cutter density plus parabolic crown preserves ROP without losing toolface control.
Cutting system: 16 mm PDC cutters staged for load sharing. The layout reduces torque ripple, keeping MWD/LWD telemetry stable and motors in the sweet spot.
Hydraulics & cleaning: Deep-blade channels accelerate fluid over the face; 5-nozzle configuration supports both jetted and higher-flow programs to keep returns crisp and temperatures down.
Compatibility: 3-1/2" API REG fits common 6–7" BHAs; no exotic makeup required, easing multi-rig deployment.
Customization & QA: Optional nozzle kits, cutter grades, and gauge protection packages; factory inspection and video reports available on request to support pre-spud QA packs.
Operating practice: Start mid-rpm/low-WOB, confirm smooth torque and uniform cuttings, then walk up together while monitoring differential pressure and vibration.
Procurement teams value predictability. This PDC drilling bit ships with a clear operating window, API-standard connection, and configuration options that map to your fluid and BHA constraints. Manufacturing capacity supports both pilots and urgent replacements, while MOQ-friendly ordering keeps inventory lean. The gauge armor and cooling efficiency translate to longer dwell on bit and fewer re-runs, reducing logistics touches and tripping exposure. Field notes from supervisors highlight easier toolface holding and quieter pumps—signs of efficient cleaning and stable torque—so crews spend more time drilling and less time diagnosing dysfunction. Technical support includes parameter guidance and post-run dull-grading review.
Q1. Which formations deliver the best ROI?
Medium-hard to hard intervals—hard shale, limestone, dolomite, and abrasive sandstones—where cooling and gauge retention curb wear and sustain ROP.
Q2. Will it fit my fleet and BHAs?
Yes. The 3-1/2" API REG pin integrates with standard 6–7" assemblies used in water-well, HDD, and many O\&G workovers.
Q3. How should I set parameters at spud?
Begin mid-rpm with lower WOB, verify clean returns and steady torque, then increase together within the 60–300 rpm and 20–125 kN window while tracking vibration and ∆P.
Q4. Can I specify cutters/nozzles?
Yes—nozzle kits, cutter grades, and gauge protection are configurable. We can align selection with your mud weight, motor specs, and expected lithology transitions.
