Product Q&A

Q:What formations is the flat top PDC bit best suited for?

It performs best in soft to medium formations including clay, silt, sand, sandy loam, and weathered shale.

Q:Can this bit handle gravel or small boulders?

It can handle minor gravel layers, but for heavy gravel or cobble formations, we recommend a more aggressive concave design.

Q:What rotation speed is recommended for soft formation drilling?

For soft formations, we recommend 80-150 RPM for optimal penetration and cuttings removal.

Q:How do I prevent bit balling in sticky clay?

Maintain adequate water or mud circulation, reduce WOB slightly, and increase rotation speed to flush cuttings effectively.

Q:Is this bit suitable for directional drilling?

No, this flat top design is primarily for vertical drilling applications. For directional work, please see our PDC directional bit series.
