What Drill Speed Should I Use When Cleaning a Pipe with a Flexible Shaft?

Drain Cleaning, Drills

The appropriate drill speed varies depending on the job and the equipment you’re using. Here’s a quick guide to help you choose the ideal RPM based on the type of cleaning:

Recommended Drill Speeds:

General Cleaning (light debris, grease, soft scale):
1,000 – 1,500 RPM
Best for PVC and softer materials.
Descaling Cast Iron or Metal Pipes (moderate to heavy scale):
1,500 – 2,500 RPM
Ideal with heavy-duty chains, carbide tips, or rasping tools.
Hard Descaling (roots, thick deposits):
2,000 – 3,000 RPM
Use only if your drill has sufficient torque and the shaft/tool is rated for high-speed operation.
