Impregnated diamond core bits are another PADC specialty. These bits, which have diamonds evenly distributed throughout the matrix, are ideal for continuous coring in abrasive formations, such as the iron-rich soils found in parts of Guinea-Bissau. PADC's impregnated bits are available in a range of diamond concentrations, allowing clients to match the bit to the rock type.

PADC's contract model is designed for large clients. They offer multi-year agreements with fixed pricing, protecting clients from market fluctuations, and they can customize delivery schedules to align with project timelines. For example, a mining company planning a six-month exploration campaign can pre-order all their surface set core bits upfront, with PADC storing the inventory and delivering in monthly batches to avoid storage issues on-site.

While PADC primarily serves big players, they also work with government agencies, such as Guinea-Bissau's Ministry of Infrastructure, on large-scale water supply projects. Their ability to handle high-volume orders and provide consistent quality has made them a trusted partner for major development initiatives. For companies in Guinea-Bissau with large drilling needs, PADC offers the reliability and scale to get the job done.
