The Rock Boring Worm Screw is designed to be used when the pipeline is filled with small rocks and stones.
The most frequent occuring problem that this tool is used for is to clear pipelines that have been blocked after a storm has carried alot of debris into the sewer system. This tool does not remove the debris, but instead is used to get the water flowing again.
Once the water is flowing, other tools such as the Drop Scraper can be used to remove the debris.
Our Rock Borer is only available in one size, and is only available for 8mm Rods. If however you require a different size, please contact us, we will custom make any tools that you may require.
