Coal mine drilling demands cost-effective, durable PDC inserts for horizontal holes, gas drainage, and roof bolting. Among common sizes, 0808 PDC inserts (8mm×8mm) are the most widely used for small-to-medium coal drill bits. As a trusted provider of ODM Pdc Bit solutions, Ninestones Superabrasives offers stable-priced, high-quality 0808 PDC inserts tailored to Oman’s coal and soft rock formations.
0808 PDC Insert: Core Specs & Price Range
The 0808 PDC insert is a standard small-size cutter for coal drill bits, featuring a diamond layer thickness of 0.8mm and a total height of 8mm. It balances wear resistance and impact toughness, ideal for soft coal, shale, and weak sandstone.
Per industry data from PDC Cutter World (a leading global superabrasive portal), 2026 wholesale prices for 0808 PDC inserts range from $3.5–$5.8 per piece, depending on grade, batch quantity, and customization.

Ninestones Superabrasives’ 0808 inserts adopt deep cobalt leaching tech (per PDC Cutter World standards), boosting thermal stability to 720°C—critical for coal drilling’s high friction heat. Bulk orders (10,000+ pcs) get a 5–8% discount, making them perfect for ODM Pdc Bit manufacturers.
Key Factors Affecting 0808 PDC Insert Pricing
- Diamond Powder Quality: Premium synthetic diamond (6–8μm grain) costs 15% more than standard powder but extends lifespan by 30%. Ninestones uses high-purity diamond for 0808 inserts, ensuring consistent performance.
- Substrate Hardness: Tungsten carbide substrates with HRA 92–93 offer better impact resistance, adding $0.3–$0.5 per piece. This is vital for Oman’s interbedded coal-shale formations.
- ODM Customization: ODM Pdc Bit clients often require custom chamfers, logos, or special bonding—these add 5–10% to unit price but enhance brand value.
- Batch Consistency: Ninestones’ 0808 inserts undergo 100% C-Scan testing to eliminate internal cracks, reducing on-site failures by 40% vs. low-cost alternatives.
Oman Coal Field Case: 0808 Inserts Cut Costs by 35%
In 2025, a major Omani coal contractor tested Ninestones’ 0808 PDC inserts vs. generic alternatives on ODM Pdc Bit roof bolting bits in the Al Kamil coalfield.
| Metric | Generic 0808 Inserts | Ninestones 0808 Inserts |
|---|---|---|
| Service Life | 120–150 meters | 280–320 meters |
| Bit Changes per Shift | 3 changes | 1 change |
| Total Daily Cost | $1,200/day | $780/day |
“We’ve tried many suppliers for ODM Pdc Bit components, but Ninestones’ 0808 inserts deliver the best value—stable price, long life, and zero quality issues.”
