Comparing Wet vs. Dry Metal Cutting: Everything You Need to Know from Tools, Mistakes to Avoid, & More
Whether it is for a new pipe system or to build the structure of a new building, metal cutting is an essential part of many projects. It can seem intimidating to attempt to cut through such a hard material using blades and saws, but it can be done safely and efficiently with proper knowledge and preparation. Two of the most popular metal-cutting methods are wet and dry. Depending on the material, type of cut, tools, and more, it is important to know when each should be used. In this blog post, we’ll break down wet vs. dry metal cutting methods, the tools you need for each, common mistakes to avoid, and more!


Why Can't You Just Apply Paint Directly to Wooden Furniture?
DIY projects can be exciting to start, but it’s important to take the time to prepare your items properly before you start painting. Applying paint directly to wood without sanding and priming first can lead to bubbling, peeling, or chipping over time. This is because the texture of wood is not smooth and more porous than other materials. Sanding and priming the surface will help to give you a smooth, even coat of paint that will last for years.
Working with Metal Increases Safety Risks
Metal is a hard material that needs to be handled with care as it may cause serious injury if not treated properly. For professional construction workers, plumbers, and more, working with metal can be a regular part of their job, but even the most experienced workers should exercise caution to prevent accidents. When metal is being cut, it tends to create sparks. If these sparks come in contact with flammable material, they can cause a fire or explosion. By taking the time to use proper techniques, you can help to prevent any potential risks.
Everything to Know About Wet-Cutting Metal
What is Wet-Cutting for Metal?

Wet-cutting is a method of slicing metal that uses a coolant liquid, such as water, to decrease the heat and friction between the blade and metal. This reduces the sparks that are created during the process.
What Tools Do I Need to Wet-Cut Metal Sheets, Pipes, & Objects?
You will need an abrasive saw with a water supply to wet-cut metal. The types of saws that are most commonly used for this method include chop saws, circular saws, and band saws. To apply the coolant, you will need a pump and nozzles to direct the liquid onto the blade.

Common Mistakes to Avoid When Wet-Cutting Metal
When you are using an abrasive saw to wet-cut metal, it is important to take caution. Some common mistakes you want to avoid when wet-cutting metal are:
Interruption of Water/Coolant Application: Most importantly, ensure the coolant liquid flows correctly and evenly throughout the cutting process. If there is an interruption in the water supply, it can lead to dangerous sparks or even cause the blade to break.
Incorrect Clamping or Securing of Metal: In addition to the consistency of the coolant, it is also important to avoid incorrect clamping techniques. If you do not securely hold the metal in place while cutting, the object will likely move and can potentially cause serious injury.


Everything to Know About Dry-Cutting Metal
What is Dry-Cutting for Metal?

Dry-cutting is a method of cutting through metal without using a coolant liquid. Instead of using a liquid to reduce heat and friction, dry-cutting relies on blades that are either made out of or covered in, a material that can withstand the heat and friction the metal creates. Usually, diamond blades are used for dry cutting due to their hardness and durability.
What Tools Should I Use to Dry-Cut Through Metal Framework, Pipes, & More?
Similar to wet-cutting, for dry-cutting metal, you will need to find a saw that is suitable for the material. Types of saws that work best include chop saws, circular saws, and band saws. As mentioned earlier, choosing a blade that can withstand the heat and friction created during dry-cutting, such as diamond blades, is important.
Common Mistakes to Avoid When Dry-Cutting Metal
As you use a blade that is harder than the metal, dry-cutting can be hard on your tools. In order to avoid damages or accidents while cutting metal, here are some common mistakes to look out for:
Incorrect Blade Speed: When you are dry-cutting through metal, it’s important to pay attention to the speed of the blade. If your blade goes too fast, it can cause the metal to bend or flex and break your blade. On the other hand, if it’s moving too slowly, heat will build up in your saw and potentially damage it.
Incorrect Clamping: As with wet-cutting, ensure you securely clamp down whatever metal object you are cutting. Moving objects is dangerous and can cause serious harm.
How to Choosing the Right Method for Cutting Metal: Wet vs. Dry-Cutting
Now that you’ve learned more about wet and dry metal cutting, it’s time to decide which method is right for your project! Here are a few factors to consider when making your decision:
Type of Metal
Dry-cutting is usually recommended if you are cutting through a softer metal, such as aluminum. On the other hand, if you are working with harder metals like steel or iron, it’s best to opt for wet-cutting.

Type of Cut & Finish
As wet-cutting creates more sparks and requires a coolant, it tends to produce a less precise cut. Dry-cutting may be the better option for more intricate and detailed cuts and a cleaner finish.
Tools & Equipment Available

Depending on the type of saw you are using and the blade and coolant equipment available, one method might be more accessible than the other. Make sure to have all the necessary tools and materials on hand before beginning your cutting process.
