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. In order to make it easier for you to choose the right cutter bit for the job, we’ve created a FREE Rehab Cutter Bit Selection Guide.

Why You Need Sewer Rehab Equipment Training

There’s nothing like spending good money on tools and then not being able to use them to their fullest potential. While you can often expect a learning curve, you should never invest in new equipment without being guaranteed support and training. Knowing how to properly run and maintain your equipment will keep it functioning well, prevent excessive downtime and keep your crew safe.

Staying Safe on a CIPP Installation Site

Posted by Nicole Lygo on Mar 28, 2019 4:48:09 PM

Today, nearly 50% of pipe repairs use cured-in-place pipe (CIPP). Though it was only invented in the early 1970s, CIPP’s ability to create a durable, corrosion-resistant new pipe without the hassle and danger of dig-and-replace made it an immediate success. But, like other construction methods, it has its risks. Using the right safety equipment and taking advantage of new, safer technologies ensures workers are exposed to fewer hazards on the job site.

Point Repair or End-to-End?

Posted by Katie Breeden on Mar 21, 2019 11:49:51 AM

Determining the right sewer rehabilitation method for a given job is not always straightforward, as identifying a solution requires evaluating a pipe’s physical environment and condition. Without properly assessing these factors, municipalities risk only partially solving a problem with point repair. Or, an equally inefficient outcome, waste resources by doing more work than necessary with end-to-end repair. While some municipalities have rehab contractors that also provide consulting services to address what type of solution is best, at the end of the day someone must make a decision on how to repair the pipes. So what should be taken into account?
