How to Use a Pipe Cutter

Q: What types of pipes can you cut with a pipe cutter?

A pipe cutter is typically designed for cutting soft metal pipes such as copper, brass, and aluminium. Some models can also handle thin-walled steel or plastic pipes, but this depends on the cutter type and blade quality. It’s important to check the manufacturer’s specifications before use, as using the wrong cutter on a hard or thick material can damage the tool or produce an uneven cut. For plastic pipes, a dedicated plastic pipe cutter is usually recommended for cleaner results.

Q: How do you get a clean, straight cut when using a pipe cutter?

To achieve a clean, straight cut, it’s essential to properly secure the pipe and tighten the cutter gradually. Start by marking your cutting point clearly, then position the cutter wheel on the mark and rotate it around the pipe, tightening slightly after every full rotation. Avoid rushing the process or over-tightening too quickly, as this can deform the pipe. A steady, consistent approach ensures the cutter scores the pipe evenly until it separates cleanly.

Q: Do you need to deburr a pipe after cutting it?

Yes, deburring is usually necessary after cutting a pipe, especially with metal pipes like copper. The cutting process often leaves behind a sharp inner edge or small burrs that can restrict flow or damage fittings. A deburring tool or even a file can be used to smooth the inside and outside edges of the cut. This step is particularly important for plumbing applications where secure, leak-free joints are required.

Q: Can a pipe cutter be used in tight spaces?

One of the advantages of a pipe cutter is its ability to work in relatively tight or confined spaces. Compact cutters are designed to rotate around the pipe with minimal clearance, making them ideal for plumbing work under sinks or behind fixtures. However, you still need enough room to rotate the tool fully around the pipe, so extremely cramped areas may require a mini or specialised cutter designed for restricted access.

Whether you’re cutting copper pipe for a plumbing repair, trimming plastic waste pipe, or working with steel tubing for a DIY project, knowing how to use a pipe cutter correctly ensures accurate clean cuts. Pipe cutters are designed to create smoother, more precise cuts compared to using a standard hacksaw. When used properly, they reduce the risk of rough edges and minimise the chance of damaging the pipe.

In this guide, we’ll explain how to use a pipe cutter step by step, including how different types of pipe cutters work, along with handy tips for achieving a professional-quality finish. Before we jump into the how-to, let’s look at the different types of pipe cutter to choose. Let’s take a look at these below.

The Different Types of Pipe Cutters

Autocut Pipe Cutter

An autocut pipe tool is a self-adjusting cutter typically used for quick, clean cuts on plastic pipes such as PVC and plastic waste pipes. It’s particularly useful in tight or awkward spaces where you don’t have room to rotate a traditional cutter around the pipe. The spring-loaded mechanism clamps and cuts as you squeeze the handles, making it a fast, one-handed option perfect for repetitive work or simple domestic plumbing tasks.

Ratchet Pipe Cutter

A ratchet pipe cutter is designed for situations where space is limited but a more controlled, gradual cut is needed. It works by using a ratcheting mechanism allowing you to tighten and cut the pipe in stages rather than all at once. It’s great for cutting copper and plastic pipes neatly without crushing or deforming them, and it’s a popular choice for plumbing work in confined areas like under sinks or behind kitchen and bathroom appliances.

Adjustable Pipe Cutter

An adjustable pipe cutter is the more traditional wheel-style tool, commonly used for copper, brass, and sometimes steel pipes. It features a cutting wheel and adjustable screw mechanism that gradually tightens around the pipe as it is rotated, scoring deeper with each turn until the cut is complete. This type is ideal when precision and a perfectly straight edge are important, especially for professional plumbing or heating installations where a clean, accurate finish is required.

How to Use the AutoCut Pipe Cutter

Position the tool around the pipe where you want to cut.
Make sure the pipe is fully seated in the tool’s cutting jaws.
Squeeze the handles together firmly.
Continue squeezing until the cut is complete (it will usually snap through in one motion).
Release the handles and remove the pipe, checking for a clean edge.

How to Use the Ratchet Pipe Cutter

Open the cutter fully and place it around the pipe at the cutting point.
Close the jaws so the blade sits on the pipe surface.
Squeeze the handles to begin the first cut, then release slightly.
Repeat the ratcheting motion, tightening and cutting gradually with each squeeze.
Continue until the pipe is fully cut through, then release and remove the cutter.

How to Use an Adjustable Pipe Cutter

Place the cutter around the pipe and align the cutting wheel with your marked cut line.
Tighten the screw until the wheel grips the pipe lightly.
Rotate the cutter around the pipe 360° to score a groove.
Tighten the screw slightly after each full rotation.
Keep rotating and tightening until the pipe is cut through cleanly.
