Gearing Up for the Job

Cutting metal with a multi tool can be a daunting task, but it doesn’t have to be. Prior to beginning, it’s crucial to ensure you have certain safety equipment readily available.

Goggles: Safety goggles should always be worn when cutting metal, as sparks and debris will fly off the material during the process. It is also important to wear them even if your face shield or helmet has an eye protection component built-in because they provide additional protection from flying particles and dust.

Gloves: Wearing gloves while using a multi-tool is essential for protecting your hands from the sharp edges of the metal being cut and any debris that may come into contact with them during the cutting process. Leather gloves are best for this type of work as they provide a good grip and protect against cuts or abrasions better than other materials such as cloth or rubber.

Dust Mask: A dust mask should also be worn when cutting metal with a multi-tool since fine particles of dust will become airborne during the process, which can cause respiratory irritation if inhaled over time. The mask should fit snugly around your nose and mouth so that no air can escape through gaps in order to ensure maximum protection from harmful particulates in the air.

To achieve the best results when cutting metal with a multi-tool, it’s important to consider the type of material you’re working with and select the appropriate blades or discs accordingly. These include diamond blades, carbide blades, grinding wheels and sanding discs. It is important to select one appropriate for your specific project before beginning work in order to avoid damaging either yourself or the material being worked on due to improper selection of tools.

Having the right tools for the job is essential to any project, and cutting metal with a multi tool is no different. Now that you’re prepared, let’s get started.

Key Takeaway: When cutting metal with a multi-tool, it is important to wear safety goggles, gloves and a dust mask for protection. Additionally, selecting the right type of blade or disc for the material being worked on will ensure optimal results.

Getting Started

Before you start any project, it’s important to make sure that your multi tool is properly set up and ready to go. Here are the steps for getting started:

Preparing Your Multi Tool

The first step in preparing your multi tool is to ensure that all of its components are securely attached. Check each part of the tool, such as the blade guard, handle, battery pack and cutting blades, making sure they’re firmly connected before turning on the power switch. Additionally, check that there isn’t any debris or dirt blocking any of the parts from working correctly. Once everything looks good and secure, you can turn on your multi tool and get ready for action.

Selecting The Right Blade

Once you have powered up your multi tool, it’s time to select which blade will be best suited for your project. If you’re looking to cut metal, then a metal-cutting blade should do just fine; however, if you need something more precise, then consider using a diamond-coated blade instead, as this type of blade will provide an even cleaner cut than other blades available. It’s also important to note that different types of metals require different types of blades, so make sure you know what kind of material you’ll be cutting before selecting one.

Prepping The Metal For Cutting

Finally, once everything has been prepped properly, it’s time to begin cutting.

Now that you’ve got the basics down, it’s time to move on to the next step: making the cut with a multi tool.

Key Takeaway: Before starting a project with a multi tool, make sure it is properly set up and ready to go. Select the right blade for your project depending on the type of metal you’ll be cutting, and prep the metal accordingly before beginning.

Making the Cut

Cutting with a multi tool can be intimidating, but it doesn’t have to be. With the right technique and some practice, you’ll be making clean cuts in no time.

Controlling Speed and Pressure

When cutting with a multi tool, controlling speed and pressure is key for achieving a clean cut. The slower you go, the more control you will have over your workpiece. As well as this, applying too much pressure can cause the blade to slip or break, resulting in an uneven cut or even injury if not careful. To ensure optimal results when using your multi tool for cutting applications, start off slowly at first until you get used to how it works before increasing speed gradually as needed.

Keeping It Clean

To keep your cuts looking neat and professional every time, use masking tape along both sides of where you want to make the cut – this will help prevent chipping on either side of the material being worked on while also providing guidance for keeping straight lines during longer cuts. For extra protection against splintering wood fibres during sawing operations, use the sandpaper after each pass of the blade – this will help reduce friction between surfaces resulting in smoother edges that require less finishing work afterwards.

Finishing Touches

Once all desired cuts are made, take some fine-grit sandpaper (around 400 grit) and lightly sand down any rough edges left behind from sawing operations. This should only take a few minutes, depending on how many pieces were cut, but it is worth doing as it helps give everything an overall polished look once finished. Finally, finish up by wiping away any dust particles created during the cutting/sanding processes with a damp cloth before moving on to other tasks related to your project, such as painting or staining etc.

Key Takeaway: Achieving a clean cut with a multi tool requires controlling speed and pressure, using masking tape to prevent chipping, sandpaper for reducing friction, and finishing up by lightly sanding any rough edges.


With the right preparation and knowledge, you can make precise cuts in no time. Now that you have all the information needed to get started, grab your multi tool and start cutting! Just remember to be safe and take your time when using a multi tool to cut metal – safety first!
