S0808 polycrystalline diamond composite sheet
Video
The 8mm flat face PDC cutter (model 0808) is a compact and high-strength polycrystalline diamond compact. It is manufactured by sintering a precision polycrystalline diamond layer on a cemented carbide substrate through high-temperature and high-pressure processes. Featuring a standard size of 8mm in diameter and 8mm in total height with a flat cutting structure, it is specially designed for small-sized drill bits, core drill bits and bits with dense cutter layout. With stable shearing performance, excellent heat dissipation and reliable durability, this cutter is perfectly adapted to soft and medium-soft formations, serving as a high-cost-performance core component for PDC drill bits.

Precise Size Specifications
This 8mm flat face PDC cutter adopts high-precision standardized dimensional design. The standard finished product has a diameter of 8.0±0.05mm and a total height of 8.0±0.1mm, with a standard diamond layer thickness of 1.5±0.05mm, and customized diamond layer thicknesses of 1.0mm and 2.0mm are available on request. It adopts refined chamfering technology overall, with a 0.4mm×45° chamfer on the diamond end face and a 0.76mm×45° chamfer on the cemented carbide substrate. All dimensional tolerances are strictly controlled, which is highly compatible with various standard and customized small-sized PDC drill bits, featuring high fitting accuracy and universal applicability.
Material and Core Technology
Sintered under the extreme environment of 5–6GPa pressure and temperature above 1500℃, the diamond layer and carbide substrate are tightly combined into an integrated structure, avoiding delamination and falling off in long-term service.
CNC precision grinding ensures ultra-high dimensional accuracy and smooth surface finish. The optimized chamfer design disperses internal stress concentration and effectively reduces the risk of edge chipping.
Application Field
