💎 PDC Cutters Overview

PDC (Polycrystalline diamond compact) Cutters are composed of a polycrystalline diamond layer and a tungsten carbide substrate. The diamond layer possesses extremely high hardness and abrasion resistance, while the tungsten carbide substrate greatly improves the malleability and weldability of the whole composite. These are widely used in oil well drilling, geological exploration, coalfield mining, and the mechanical industry.

Material: PDC (Polycrystalline Diamond Composite)

Diameters: 13mm, 16mm, 19mm

Tools: PDC Drill Bits, PDC Reamers

Types: Flat, Convex, Helmet, Ridge, Half cut

Our PDC cutter inserts are suitable for soft to hard geological terrane. We offer various claw structures and chamfer types, with options for grinding and polishing based on specific customer requirements.

💡 Selection Method

Large cutters (16-19mm) are more aggressive than small cutters (8-13mm) but may increase torque fluctuations. Small cutters (8mm, 10mm, 13mm) provide higher cutter density, enabling them to withstand higher impact loading and often achieving a higher ROP (Rate of Penetration) in applications like limestone.

Additionally, large cutters produce larger cuttings, which requires efficient drilling fluid to carry the debris. We maintain consistent quality across all sizes, with our 16mm and 19mm cutters competing with premium industry standards.

❓ Frequently Asked Questions

What is the composition of a PDC cutter?

PDC cutters consist of a polycrystalline diamond layer bonded to a tungsten carbide substrate, combining extreme hardness with high weldability.

Which industries typically use these cutters?

They are primarily used in oil and gas drilling, coal mining, stone cutting (like marble quarrying), and geological exploration.

How do I choose between large and small cutters?

Large cutters (16-19mm) are more aggressive, while smaller cutters (8-13mm) offer higher stability and better impact resistance in certain hard formations.

What shapes of PDC cutters are available?

We offer multiple shapes including flat face, convex face, helmet face, ridge face, and half-cut types to suit different drilling needs.

What is the typical delivery time for an order?

Standard delivery time is usually between 3 to 5 business days, depending on the specific requirements and stock availability.

Are the cutters certified for quality?

Yes, the products are manufactured under ISO9001 certification standards to ensure high performance and consistency.
