Every plumber – regardless of whether they are a professional or an amateur – will need a variety of tools to get the job done.

Having the right plumbing tools will make your life a whole lot easier and enable you to complete plumbing installations, maintenance and repair jobs in next to no time – without sacrificing safety or quality.

How do you know which are the best plumbers’ tools and which should you add to your toolbox, if you haven’t already? Luckily for you, we have put our heads together and compiled a list of ‘must-have plumbers’ tools’, including radiator keys, pliers, plungers, spirit levels and more.

When shopping for plumbers’ tools, remember that your time, safety and quality of work is most important. With this in mind, we suggest looking for ones that are durable, easy to use and, where possible, designed specifically for plumbers.

Pipe Cutters

Every plumber should have a few of these pocket-sized tools. Pipe Cutters (also known as an Automatic Pipe Cutter, Pipe Slice and Single Handed Pipe Cutter) can cut through most piping with ease. They produce a cleaner cut than using a hacksaw, more importantly, they are quicker. They can be used in tight spaces which makes them ideal for plumbing use.


Circular pipe cutters are not adjustable so it is recommended that you purchase the most common diameters of copper piping (8mm, 10mm, 15mm, 22mm and 28mm). When picking a copper pipe cutter, you want to ensure that it’s lightweight but sturdy enough to make the cut clean and precise. If you can avoid or remove any external burrs at the same time, the more the better.

The Adjustable Tube Cutter (or Telescopic Tube Cutter) is a must have tool for any plumber. It can cut pipes and tubing 6 – 35mm in thickness. Perfect for those jobs your circular pipe cutter can’t manage.
