S1013 Flat PDC Cutter for PDC Drill Bits in Shale and Mixed Formations

S1013 is a high‑performance polycrystalline diamond cutter (PDC cutter) designed for oil and gas drilling. It is manufactured from premium polycrystalline diamond layer and high‑strength tungsten carbide substrate under high‑pressure high‑temperature (HPHT) sintering. It combines the extreme hardness of diamond and the excellent toughness of carbide, suitable for soft to medium‑hard formations.

This PDC cutter is engineered to work steadily across multiple geological formations. It performs well in soft formations including mudstone, shale, sandstone and coal seams. For medium-soft strata such as siltstone, argillaceous sandstone and weakly consolidated sandstone, it maintains high drilling efficiency. It also adapts to medium-hard formations like quartz sandstone, limestone, dolomite and strata with gravel interbeds. 

Core Product Advantages

Superior Wear Resistance
High‑purity diamond powder with dense microstructure. Wear ratio over 300,000+. Stable performance at 700°C, significantly extending bit life.

High Impact Toughness
Optimized non‑planar interface reduces shear stress. Withstands 450J vertical impact energy. Less chipping and breakage in hard streaks.

Excellent Thermal Stability
Deep cobalt leaching blocks heat conduction. 10 thermal cycles at 750°C without damage. Resists thermal softening in deep wells.

High Cutting Efficiency
Optimized diamond thickness (1.8 mm) and sharp edge. Lower cutting resistance. ROP improved by 15%–25%, shorter drilling cycles.

Precision Dimension Control
Full‑size precision grinding, tolerance ±0.02 mm. Excellent flatness and balance. Reduces vibration and premature wear.

Long‑Life Stable Performance
Works under high RPM and high WOB. Single bit footage 3,000–6,000 m. Reduces trips and operational cost.

Precise Size Specifications

For polycrystalline diamond cutters, the standard size of S1013 is 10.00 mm diameter, 13.2 mm total thickness, 1.8 mm diamond layer, with optional 0.3×45° or 0.5×45° chamfer. It is fully compatible with mainstream sizes including 1308 (13.44×8 mm), 1613 (16×13 mm), 1616 (16×16 mm), and 1919 (19×19 mm). Custom diameter, total thickness, diamond thickness and chamfer can be tailored to different bit designs, hole sizes and formation requirements.

Material and Core Technology

Core Material

Made with a premium cemented carbide substrate combined with high‑purity PCD polycrystalline diamond material. The substrate features high hardness and toughness, while the diamond layer delivers outstanding wear resistance, fundamentally improving product durability and service life in harsh drilling conditions.

Production Process

Adopts industrial‑grade high temperature and high pressure (HTHP) integrated sintering technology. The PCD diamond layer is seamlessly fused with the cemented carbide substrate with high bonding strength. It effectively avoids delamination, chipping and cutter detachment during long‑term high‑pressure drilling, with far better process stability than products made with ordinary bonding technology.

Quality Control

All production complies with ISO9001, ISO14001 and ISO45001 international standards. Three‑level inspection is carried out on raw materials, semi‑finished products and finished products. All key performance indicators — including impact toughness, high‑temperature resistance and wear resistance — are strictly tested to meet stable quality standards. Factory direct supply ensures fully controllable quality and traceability.

Application Field

Oil & Gas Drilling
As one of the reliable polycrystalline diamond cutters, it is suitable for shallow to medium‑deep well operations on land. Works well in tight sandstone, interbedded strata and gravel‑bearing formations. Its 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: How to choose between S1013, 1308, 1613, 1616 and 1919?
A: Soft formation/high ROP → 1308; medium‑hard/balanced performance → S1013/1613; hard formation/long life → 1616/1919.
Q: Can S1013 drill hard granite?
A: S1013 suits soft–medium‑hard formations. For hard granite, choose larger size with thicker diamond layer (1919) or customized high‑impact grade.
Q: What quality control do you have?
A: ISO 9001 certified. Raw material 100% inspected. Each batch tested for wear, impact and thermal stability. Full test reports provided.
Q: What is lead time and MOQ?
A: Standard: 3–7 days. Custom: 10–15 days. MOQ: 100 pcs. Small trial orders accepted.
