Price Range & Key Factors for 19mm PDC Inserts
Based on data from Kingpdc and Tankdrill industry reports, 19mm PDC insert prices typically range $28–$48 per piece for bulk orders (50+ pieces) from professional PDC Insert Supplier factories. Three main factors drive this range:
- 1 Diamond Layer Grade: Premium 19mm inserts use 92%+ purity diamond powder with 2.0–2.5mm thickness, boosting heat resistance (up to 750°C) and wear life by 30% vs. standard grades.
- 2 Carbide Substrate Quality: High-grade tungsten carbide substrates (HRA 89–91) add $4–$6 per piece but reduce chipping in Algeria’s abrasive sandstone and hard limestone formations.
- 3 Manufacturing Process: HPHT-sintered (5,500+ bar) 19mm inserts from reputable PDC Insert Supplier partners cost 15% more but eliminate delamination risks, a common failure issue in local deep wells.
Why 19mm Inserts Are Standard for Large-Diameter Bits
Large bits (17 ½” and above) require cutters that can handle high torque and heavy load—19mm PDC inserts are the ideal choice, as noted by Drilling Contractor‘s 2026 bit design guide.
- ◆ Load Distribution: 19mm inserts have 40% more contact area than 16mm cutters, reducing localized wear in Algeria’s high-ROP water well and oilfield projects.
- ◆ Thermal Dissipation: Larger diamond layers in 19mm inserts dissipate heat faster, critical for deep wells (3,500m+) in the Hassi Messaoud basin where bottomhole temperatures exceed 700°C.
- ◆ Bit Stability: 19mm inserts improve bit balance in large-diameter holes, reducing vibration and extending bit life by 25% compared to smaller cutters.
Algeria Field Case: 19mm Inserts Cut Costs by 35%
A major Algerian drilling contractor recently tested 19mm PDC inserts from Ninestones and a generic PDC Insert Supplier on 17 ½” bits for a 4,200m water well in the Sahara Desert (abrasive sandstone, hard shale interbeds).
| Metric | Generic 19mm Inserts | Ninestones 19mm Inserts |
|---|---|---|
| Price per piece | $28 | $36 |
| Run time | 12 hours | 28 hours |
| Bit trips | 5 | 2 |
| Total drilling time | 68 hours | 44 hours (35% faster) |
| Issues | Frequent chipping & thermal wear | Zero chipping, 40% lower tool cost |
