165mm 4‑Blade Arc‑Shape PDC Bit

Our 165mm 4‑blade arc‑shape PDC bit is engineered and manufactured for challenging hard rock drilling scenarios, equipped with premium grade 1613 super‑hard PDC cutters to deliver outstanding rock breaking performance in abrasive and compact formations.

Adopting optimized arc‑shaped blade structure design, this PDC bit realizes smooth rock‑cutting trajectory, effectively reduces impact load and abrasive wear on PDC cutters while improving bit stability during downhole operation. The bit is configured with robust 3 1/2 REG connection thread, which ensures reliable connection strength, convenient assembly and disassembly, and good compatibility with standard drill strings for mining, coal and geological drilling projects.

Built for tough working conditions, this 165mm PDC bit performs excellently when drilling hard formations including quartz stone, granite, limestone and basalt. It is widely deployed in coal mine drilling, geological exploration, water well drilling and rock bolting projects. The 1613 super‑hard PDC composite cutters feature high hardness, strong impact resistance and anti‑abrasion property, greatly extending bit service life and lowering overall drilling cost per meter.

As a professional PDC bit manufacturer, we strictly control raw material selection, welding process and finished‑product inspection. Customization on blade layout, cutter configuration and bit parameters is available to match your specific rock condition and drilling requirements. Contact us for quotation and technical data sheet.
