Optimizing Rehab Cutter Performance with Cutter Bit Selection

Posted by Venay Sehgal Bhatia on Jun 11, 2019 12:16:00 PM

Sewer rehabilitation cutter operations require a great deal of attention to detail. Whether you’re using a cutter to reinstate lateral connections or to repair defective liner, whether you’re preparing for CIPP work or ready to grind away protruding taps—the job on hand is an important one and requires precision and experience. However, even the most advanced lateral and mainline rehabilitation and reinstatement cutters can’t work effectively without the right cutter bit. Cutter bits can make or break a job, and choosing the wrong one can damage your cutter, slow down your team and add unnecessary time and cost to projects. Getting acquainted with the various cutter bits’ purposes can increase the quality of rehabilitation projects, productivity of operators and lifetime of your rehabilitation cutter.

Cutter bits come in a variety of sizes, shapes and material—all with a special job on hand. Cutter bits designed for one pipe material or size may not be suitable for use in another. Pipe diameter limits how a cutter can maneuver and articulate itself to perform rehab, and your cutter and bit size will usually dictate the size of the pipe you can work in. If you choose a bit that’s too small, you may waste time and money if the project takes longer than intended. If you use a bit that’s too big, you risk damaging pipes.

In addition to size, cutter bits come in different shapes—designed to perform very specific jobs. Some can cut pipes and liners, while others are intended for finishing. Material, bit shape and size of the pipe are all very important to take into account when choosing a bit. Just some examples of the specialized bits available include

    • Corundum cup wheel. Used to grind offsets, protruding taps and general defects in 4-28” metal pipe
    • Diamond milling tools. Used to grind offsets, protruding taps and general defects in 6-16” concrete and stone pipe
    • Diamond cone. Used for cutting pvc, grp and felt liners, as well as for roots and calcification in 4-16” plastic pipes
    • Carbide half globe. Used to finish 3-10” pipes and to cut pvc, grp and felt liners in 3-4” plastic pipes
    • Epulo cone and ball. Used in 8-28” lines to cut pvc, grp and felt liners and for root and calcification in plastic pipes, as well as to cut and remove failed liner
    • Brushes. Used to finish projects in 4-16” pipes

The above isn’t an expansive list, but just a small selection of the choices a sewer rehabilitation professional is presented with.

A Well Maintained Cutter is a Reliable Cutter

Posted by Nicole Lygo on Dec 29, 2017 7:52:28 PM

Your cutter can get pretty beat up in the sewers which makes regular maintenance so important. Regular maintenance can keep it running strong longer, but for a busy crew at the end of a long day, maintenance can fall by the wayside. The more often you forget to clean and check your cutter, the more damage is done, leading to downtime, decreased productivity and lost revenue. Municipal sewer rehabilitation contractors must protect their investment and business by ensuring that their equipment is in optimum working condition.

Sewer rehabilitation cutters are used to reinstate lateral connections post-lining, and for other functions like CIPP preparation (grinding away protruding taps, smoothing offsets and joints) and repairing liner defects. Even the most advanced lateral and mainline rehabilitation and reinstatement cutters can’t guarantee a precision cut without the operator choosing the right cutter bit for the job at hand.
