Core Product Advantages
Exceptional Wear Resistance
Diamond layer hardness reaches 8000–10000 HV with strong self-sharpening; outlasts carbide by 20–25× in soft formations.
Compact & High Strength
10 mm diameter with integrated tungsten carbide substrate; high structural strength resists chipping under light-to-medium impact.
Good Thermal Stability
Withstands continuous temperatures up to 700°C; low residual stress prevents delamination in shallow, high-speed drilling.
High ROP & Efficiency
Shear-based cutting (vs. roller cone crushing); improves penetration rate by 30–40% in soft rock and reduces trips.
Precision Standard Dimensions
Diameter 10.00±0.02 mm, height 8.00±0.02 mm, 0.3 mm standard chamfer; fully compatible with 10 mm PDC bit blades for easy installation.
Cost-Effective & Economical
Competitive pricing with long service life; lowers cost per meter in soft formations and maximizes ROI.
Precise Size Specifications
S1008 features standard dimensions of 10.00 mm diameter, 8.00 mm total height, 1.8 mm diamond layer thickness, and 0.3 mm diamond chamfer. Strict tolerances of ±0.02 mm for diameter and ±0.02 mm for height ensure batch consistency and interchangeability. It fits 10 mm series PDC bits (3 7/8″–6″ for water wells, mining, and shallow oil/gas), with minor dimensional adjustments available on request.
Material and Core Technology
Core Material
Made from 99.9% high-purity micron diamond powder and ultra-fine grain WC-Co carbide (6–8% cobalt) for balanced hardness, toughness, and thermal conductivity.
HPHT Sintering Process
Sintered at 1500°C, 5.5 GPa to form a strong metallurgical bond between diamond and carbide—no weak layers, no delamination, bonding strength ≥2.5 GPa.
Quality Control
All production complies with ISO9001, ISO14001 and ISO45001 international system standards. Three-level inspection is carried out on raw materials, semi-finished products and finished products. All performance indicators including impact toughness, high temperature resistance and wear resistance reach stable standards. Factory direct supply ensures fully controllable quality.
Application Field
Oil & Gas Drilling
Suitable for shallow to medium-deep well operations on land. Works well in tight sandstone, interbedded strata and gravel-bearing formations. High temperature resistance avoids carbonization and delamination, reducing bit replacement and overall drilling cost.
Mining Drilling & Exploration
Ideal for mineral prospecting, tunnel drilling and mine water well projects. Perfect for high-abrasive hard rock such as granite and quartzite. Excellent impact resistance prevents edge chipping, serving longer life in fractured mining formations.
Geological Exploration & Sampling
High dimensional accuracy ensures stable drilling and regular borehole. Guarantees complete formation core sampling, fully meeting high-precision geological survey and resource exploration requirements.
Water Well & Infrastructure Engineering
Widely used in deep water wells, pile foundation drilling and construction projects. Efficient penetration in common rock layers, low wear and stable performance for long-time continuous site operation.
Universal Bit Matching
Compatible with mainstream PDC bits, core bits and drilling tools with good interchangeability. Custom sizes and chamfers are available to meet non-standard matching demands for different projects.

FAQ
Q: What drilling scenarios is the S1008 PDC cutter most suitable for?
A: The S1008 cutter is specially optimized for shallow, soft and low-abrasion formations. It is the best choice for water well drilling, coal mine soft rock tunneling, shallow oil and gas exploration, and civil geological prospecting, and is not recommended for hard and highly abrasive complex strata.
Q: What are the key differences between S1008 and other 10mm series cutters?
A: Compared with S1013 (13.2mm height), S1008 has a shorter overall height and a more compact structure, with higher drilling flexibility and cost performance, more suitable for shallow rapid drilling; its 0.3mm ultra-thin chamfer is sharper than other models, delivering faster rock-breaking efficiency in soft rock.
Q: What operating parameters are recommended for daily construction?
A: The optimal working parameters are 8–18kN weight on bit per cutter and 100–180RPM rotating speed. Adopt low drilling pressure and high rotating speed for loose clay and mudstone; appropriately increase drilling pressure for soft fine sandstone, and keep stable mud circulation for cooling.
Q: Can S1008 work in wet and water-rich formations?
A: Yes. The integrated sintered structure has excellent waterproof and anti-corrosion performance, no delamination or rusting in long-term water-rich and wet drilling environments. It maintains stable cutting performance in conventional water well and underground wet working conditions.
Q: Does your factory support small-batch trial orders of S1008?
A: Absolutely. We support flexible order quantities. Besides bulk orders, small trial orders of 50–100 pieces are acceptable for new customers to test quality, and we can provide sample services for project verification.
