Ball heads designed for optimal in pipe negotation in smaller lines and drop heads designed to navigate down stacks in back to back applications.
  • FlexShaft Sandpaper Blades - FlexShaft sandpaper blades are a great tool to aid in pipe rehab jobs. The sandpaper attachments can be used to prep pipe before CIPP patching or relining, to smooth transition edges after a reinstatement, and as a finishing tool when descaling or milling.
