Description
A PDC bit is a high-performance drill bit commonly used in oil and gas drilling, mining, geothermal, and water well applications. It features fixed cutting elements made from polycrystalline diamond compact material, which is known for its exceptional hardness, thermal stability, and wear resistance. These properties allow PDC bits to deliver efficient, high-speed drilling in a wide range of formations, particularly soft to medium-hard rock.
The bit typically consists of a steel or matrix body with strategically placed PDC cutters designed to shear through rock using a continuous scraping action. With no moving parts, PDC bits offer enhanced durability, lower maintenance, and improved drilling efficiency compared to roller cone bits. Their design may vary in blade count, cutter layout, and hydraulic configuration to suit specific drilling conditions and maximize performance.
Application:
Medium-hard with low compressive strength , such as shale, limestone, sandstone, gypsum, etc
