How to cut PVC pipe and what is the best way to cut PVC pipe? This is one of those questions we as plumbers take for granted. However, it’s asked about quite often. When people run into problems cutting PVC pipe, it’s usually not while cutting smaller size pipe. It isn’t until you get to the larger sizes like 3” to 8” when finding the best way to cut PVC becomes a difficult job. If you keep reading, you will discover the best ways to cut PVC. This way, you can complete any project using both small and large diameter PVC pipe.

How to Cut PVC Pipe: ¼” to 2”


How to cut PVC pipe

Learning how to cut PVC pipe will teach you that a simple hacksaw does a great job cutting PVC. This holds true especially when working with small diameter pipe. Just make sure you line up the blade of the hacksaw on your measurement line and cut straight. A hacksaw will even help you figure out how to solder copper pipe by yourself.

As the diameter of the pipe is small, you don’t have a lot of surface area for the hacksaw blade to wander. Bring your arm back and forth in a straight motion. This way, you’ll be through the pipe in a couple passes.

Sawzall or Reciprocating Saw

Picture Milwaukee SawzallThe word Sawzall is Milwaukee’s name for a reciprocating saw. Tradesmen use the word Sawzall like Kleenex. Therefore, this is a brand name synonymous with the reciprocating saw. Ok, onward. So, how to cut PVC pipe?

Once again, measure twice cut once, mark your pipe where you want to make the cut. Afterward, place the blade guide tight up against the pipe and gently squeeze the trigger to start the cut.

If you fully engage the trigger, the saw can get away from you. Therefore, you want to give yourself a little rut to make the cut. Once you start cutting, keep your arm steady and open it up. It’s like a hot knife through butter.

Before you begin cutting, go out and buy several blades specific to PVC and plastic. The teeth are more course, and you get a much quicker cut. If you are using blades meant for metal, they will be smaller because the material is harder. You’ll get through the PVC eventually, but it will certainly take longer.

PVC Tubing CutterHow to cut pvc with Ridgid PVC cutter

If you’re going to be working with PVC quite a bit, this tool is absolutely worth the investment. The one I love is the Ridgid RC-237. This tool does not only work well, but it also cuts pipes of up to 2” diameter diligently.

This allows you to work on both small diameter water piping and larger diameter waste and vent piping. PVC waste and vent piping for kitchens, lavatories, and laundry tubs can be all be handled with this tool in most instances. This is most certainly a homeowner-plumbing hack. For instance, the PVC tubing cutter will help you learn how to fix a leaking PVC pipe joint quickly.

Hot to Cut PVC: 21/2” and Above


You can still use a hacksaw on larger diameter pipes if this is the only tool you have for learning how to cut PVC. However, the margin for error grows quite a bit in this case. It is difficult to keep a hacksaw on a straight cutting path when you get past 21/2” diameter pipe. A hacksaw blade bends as you move it.

Therefore, even though you’re careful, you can still experience deviations. Before you begin your cut, make sure you have the pipe anchored in a tripod vise for example. This keeps the piping in place and lessens the chance of the pipe moving. We rarely use a hacksaw to cut pipe over 2”.

Sawzall/Reciprocating Saw

As stated above, it is extremely important that the pipe is secured in some fashion. Anytime you are working with an electric powered saw, you should minimize the risk of the material moving. This will give you a sharper cut and, more importantly, keep you safe. As long as you have a long enough blade and some skills, you can cut up to 8” PVC pipe with a reciprocating saw.

Chop Saw

Milwaukee Chopsaw

When plumbers get a chop saw out on a job site, they feel like heaven. Not only is it the best way to cut PVC, but you can also cut cast iron, copper, steel, etc. Moreover, the cuts are squared off, so there is no need to file or grind down an uneven edge.

Internal PVC Pipe Cutter

Wheeler Internal PVC Cutter

Internal pipe cutters are pretty cool. They consist of a circle or a star pattern piece of metal that has blades at an edge. This insert is slightly smaller in diameter than the pipe being cut. The cutter is actually a bit smaller that fits in a ½” drill.

The internal cutters shown here have flat caps that are tightened to adjust depth. You tighten an adjustment screw to flare the cutting wheels against the inside of the pipe and pull the trigger of the drill.

Pencil Grinder

The pencil grinder is a specific tool. You can attach different types of grinder bits based on circumstances and materials. Thin flat discs are super effective with cutting PVC, cast iron, and steel. On the other hand, they are pretty damn crude. It works but only in a pinch and only at desperate times.

How to Cut PVC – Finishing Touches

The great thing about working with PVC is that it is a very forgiving material. If you have to use a hacksaw or sawzall and you find the cut isn’t exactly square, you can always use a heavy-duty file to file down the edge that needs adjusting. Learning how to cut PVC is simple, but being careful is a prerequisite.

Whenever you use a saw or grinder bit to cut PVC, you must run your finger or a cloth along the edge of the cut. This way, you remove the plastic burrs both on the inside and outside of the pipe. If there are any edges that have a hard bevel, you can use the same file used to square off a cut.
