Renssi WC-NC Series circular chain knockers without carbide give you a 360-degree mechanical cleaning setup for rotating cable and flex-shaft pipe cleaning. The circular chain arrangement positions the cleaning chains around the tool for contact with the inside of the pipe, without the carbide inserts used on more aggressive WC models.

Choose the right configuration based on your cable size and pipe diameter. The selected models cover 5/16", 3/8" and 1/2" cable with pipe sizes from 2" through 8". All three series shown here use 1/8" (4 mm) chain.

Best For

• Flex-shaft and rotating cable pipe cleaning
• Mechanical removal of pipe buildup
• Applications where a non-carbide chain tool is preferred
• 2" through 8" pipe, depending on model
