PDC Core Drill Bit

112mm PDC Core Drill Bit

This 112mm PDC core drill bit is designed for core drilling in challenging ground conditions. It is suitable for geological exploration, rock coring, mining, water well drilling, and other engineering projects. The bit features a 1305 button/cutter configuration and an additional ring of polycrystalline diamond compact on the side for gauge protection. This design helps improve gauge holding ability, impact resistance, and overall service life.

In gravel, cobble, sandy gravel, gravelly soil, and fractured formations, this PDC core bit can maintain stable cutting performance and core recovery. It is a practical choice for projects requiring wear resistance, durability, and continuous drilling performance. Compared with conventional core bits, it offers better adaptability in complex formations and can help reduce downtime caused by frequent bit changes.
