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

The right drill speed depends on the job and your equipment. Here’s a quick guide to help you choose the appropriate RPM based on the type of cleaning you’re doing:

Recommended Drill Speeds

• General Cleaning (light debris, grease, soft scale):
  1,000 – 1,500 RPM
  Suitable for PVC and softer materials.

• Descaling Cast Iron or Metal Pipes (moderate to heavy scale):
  1,500 – 2,500 RPM
  Best used with heavy-duty chains, carbide tips, or rasping tools.

• Hard Descaling (roots, thick deposits):
  2,000 – 3,000 RPM
  Only if your drill has enough torque and the shaft/tool is rated for high-speed use.

Please take a look at this short video explaining suitable torque and speed settings on your drill depending of the task at hand.

Selecting the correct drill speed is crucial for effective and efficient cleaning. By matching the RPM to the type of debris or scale you’re tackling, you can optimize your tools and avoid unnecessary wear.
