8½" PDC Bit Delivers Exceptional Performance in Brazil
Client: Johnathas, HAINASEN (Brazil)
Product: 8½" (215.9mm) PDC Drill Bit
Specifications: 5 Blades, 7 Nozzles, 4½" REG PIN Connection, 16mm Single Row Cutters
Project Overview
In a recent drilling project in Brazil, our client Johnathas from HAINASEN put our 8½" PDC drill bit to the test in challenging dolomite and quartzite formations. The results were outstanding, with the bit efficiently completing 150 meters of drilling while maintaining exceptional performance and reliability.

Client Testimonial
"Até o momento perfuramos 150 metros de DOLOMITA e QUARTZITO com essa PDC de 8.1/2" teve um rendimento ótimo.
Sim estou muito satisfeito até o momento, continue esse padrão de fabricacao que está indo muito bem."

(Translation: "So far, we have drilled 150 meters of DOLOMITE and QUARTZITE with this 8½" PDC bit, and it has shown excellent performance. I am very satisfied so far; keep up this manufacturing standard, as everything is going very well.")
Performance Highlights
Efficient Drilling: Successfully drilled 150 meters in hard dolomite and quartzite formations.
Superior Design: The 5-blade configuration, 16mm single-row cutters, and 7-nozzle layout ensured optimal cutting efficiency, chip removal, and cooling.
Reliable Connection: The 4½" REG PIN connection provided a secure and stable fit, minimizing downtime.
Next Steps
Following the success of this trial, Johnathas has expressed his intention to provide additional PDC bit specifications for a formal quotation, signaling a strong interest in expanding our partnership.
