Best All-Purpose Tools & How to Cut Metal with an Oscillating Multi-Tool

Introduction

Imagine having just one tool that can do so many different jobs—cutting, sanding, scraping, and more. Whether you’re fixing things around the house or working on a serious job site, having a versatile tool like that can save you a lot of time, effort, and even money.

This is why both DIYers and professionals love having something called a multi-tool in their kit. One job that people often wonder about is cutting metal, especially harder stuff like stainless steel.

That’s where this guide comes in to show you how to use an oscillating tool for metal cutting. You’ll know what blades to choose, and when you might need other tools like an angle grinder or circular saw instead.

What is the Best All-Purpose Tool?

When people say “all-purpose tool,” they mean something that can do lots of things, not just one. It should be easy to use, multi-functional, and work on different materials.

The oscillating multi-tool is a great example of this. It’s a good multi-tool that can handle many tasks like sanding rough wood, scraping off glue, grinding surfaces, and, of course, cutting.

Why is an Oscillating Multi-Tool a Great Pick?

The oscillating multi-tool moves its blade side to side in tiny, fast movements. That helps you make precise cuts, even in tight spaces, and avoid damaging the area around your cut.

Whether you’re trimming baseboards or trying to cut sheet metal, it gives you clean cuts and more control than many other tools. It’s also safer and easier to use, especially for beginners working on diy projects.

Oscillating Multi-Tools vs. Rotary Tools vs. Reciprocating Saws

Let’s compare it with some different tools. Rotary tools spin in circles, which can be great for detail work but not the best for metal cutting. Reciprocating saws are powerful and great for demolition, but they’re big, hard to control in small areas, and may leave jagged edges.

The oscillating tool, on the other hand, gives you accuracy and cleaner results, especially with the correct blade. That’s why many people say the oscillating multi-tool is the best all-purpose tool for small jobs, repairs, and light metal cutting tasks.

Can an Oscillating Multi-Tool Cut Metal?

Yes—it can! But only if you’re using the right blade. Not all blades are made for metal cutting, so this is your top priority when starting a metal cutting task.

When an Oscillating Tool Works Best for Metal?

If you’re working with thin metal, like sheet metal, screws, nails, or a small copper pipe, an oscillating multi tool can do the job very well. Just make sure to use carbide teeth or diamond-coated blades, which are made for various metals and give you a clean cut. It’s a great option for quick repairs, home projects, or small pieces of mild steel.

The tool also helps when you’re trying to make a straight cut in metal that’s hard to reach or close to a wall. Since the oscillating tool doesn’t spin, it’s safer to use near surfaces you don’t want to damage.

When It’s Not the Right Tool for the Job?

But let’s be honest—not all jobs are a good match. If you’re trying to cut thick metal like large steel rods or heavy-duty pipes, the oscillating tool may not be strong enough.

In that case, you’ll need the best metal cutting tools like an angle grinder, plasma cutter, or a circular saw. These tools are better at handling thicker materials and making fast, deep cuts.

Always Use Safety Gear

No matter which metal cutting tools you use, safety should always come first. Make sure to wear appropriate personal protective equipment like safety glasses, gloves, and hearing protection. The cutting process can create sparks, sharp debris, and loud noise, so don’t skip the protective gear.

Best Oscillating Tool Blades for Cutting Metal

To do any metal-cutting job properly with an oscillating tool, you need the right blade. Not every blade can handle metal, and using the wrong one can damage the tool or make the cut rough and messy.

So, let’s look at the best blades you should use, depending on the type of metal you’re working with.

Carbide Blades

If you need to cut hard stuff like old screws, nails, or hardened metal, a carbide blade is your best bet. These blades have strong, rough teeth that are made for tough jobs. One of the best metal-cutting tools in this category is the Diablo Carbide Oscillating Blade. It lasts long, cuts fast, and gives you clean cuts without breaking the tool.

Bi-Metal Blades

Now, if you’re working with thin metal sheets like sheet metal, or soft metals like copper or aluminium, then a bi-metal blade is what you need. It’s bendy, safe, and perfect for light-duty metal cutting tasks. 

The Milwaukee Bi-Metal Multi-Tool Blade is a great example. It’s reliable, and it doesn’t wear out too quickly, even if you use it a lot.

Diamond-Coated Blades

When the job is even tougher—like when you’re trying to cut stainless steel—you’ll need something extra strong. That’s when a diamond-coated blade comes in. These blades have tiny diamonds on them to make it easier to cut through hard steel and thick metal.

The Bosch OSL234DG Diamond Grit Blade is one of the best for this. It gives you precise cuts and a smooth finish, even in very hard metal.

No matter which blade you choose, always check the metal’s thickness before you begin. This helps you pick the right type of blade and finish the job safely and quickly. 

And don’t forget to replace blades when they get dull, or they won’t work well. The cutting process becomes harder, and the tool may overheat if the blade isn’t sharp enough.

How to Cut Stainless Steel with an Oscillating Tool (Step-by-Step Guide)

Step 1: Gather Your Tools & Safety Gear

Before you begin, make sure you have everything ready. You’ll need an oscillating multi tool, either corded or cordless, and a strong metal cutting blade. The best blades for cutting stainless steel are carbide or diamond-coated ones. 

You should also wear appropriate personal protective equipment, like safety glasses, gloves, and something to protect your ears. Don’t forget to clear the area of flammable materials to keep things safe. Safety is your top priority every time you work with power tools.

Step 2: Attach the Right Blade

Now that your gear is ready, it’s time to add the blade. Use either a diamond-coated or carbide blade, depending on the metal cutting job.

Make sure the blade is tight and doesn’t wiggle, because a loose blade can ruin your cutting line and even hurt you. Using the right blade for the job helps make clean cuts and keeps your oscillating multi-tool in good shape.

Step 3: Mark & Clamp the Metal Piece

Next, use a marker or chalk to draw the cutting line where you want the blade to go. A straight edge can help you draw a perfect line. Then, clamp the metal down so it doesn’t move. If the metal vibrates too much during the cutting process, it can make the cut uneven and even damage your blade.

Step 4: Make the Cut

It’s time to start cutting. Turn your oscillating tool to high speed and gently touch the steel with the blade. Let the tool do the work—don’t push too hard. Using a gentle, back-and-forth rocking motion helps the blade get deeper into the metal and gives you a straight cut with a smooth finish. 

This method is safer and easier, especially for people doing diy projects at home.

Step 5: Smooth the Edges

Once your cutting process is complete, the edges might be rough or sharp. Use a metal file or sanding pad to smooth them out. This step is very important because sharp edges can be dangerous. After smoothing, your metal cutting job is complete, and you’ve done it with the help of one of the best all-purpose tools available today.

Best Tools for Cutting Metal (Not Just Oscillating Tools)

Best Oscillating Multi-Tools for Metal Cutting

Even though there are many metal cutting tools, the oscillating multi-tool is still one of the most useful. If you want the best metal-cutting tools in this category, there are some great options.

The Fein MultiMaster 500 is known for its strength, smooth control, and ability to make clean cuts in many types of metal. 

If you’re looking for a more affordable choice, the DeWalt DCS356B is a reliable and strong multi-tool that fits most budgets.

And if you want a cordless option for more freedom while working, the Milwaukee M18 Fuel is perfect. It is light, powerful, and great for cutting metal without needing a power outlet.

Alternative Tools for Cutting Metal

Sometimes, though, you need other tools, especially when dealing with thicker materials or big metal cutting tasks. One of the most powerful tools you can use is an angle grinder. It’s perfect for thick metal, tough steel, and cutting metal fast.

If you’re cutting through pipes or doing heavy demolition work, a reciprocating saw is another great option. It’s powerful, fast, and can handle rough jobs.

For even heavier work, like in workshops or construction, a plasma cutter is the tool to pick. It uses heat and electricity to slice through thick metal quickly, even mild steel.

And don’t forget about the circular saw with a metal cutting blade. This tool is handy for making fast, straight cuts in sheet metal and thin metal panels.

Choosing between these power tools depends on what kind of metal you’re working with, how thick it is, and how accurate or fast your cuts need to be. Using the right tool always makes the cutting process smoother and safer.

Common Problems & Solutions When Cutting Metal

Problem: The Blade Gets Dull Too Quickly

If your blade goes dull fast, you might be using the wrong one. A bi-metal blade might not be strong enough for some metal-cutting tasks. Instead, try using a carbide or diamond-coated blade. These stay sharp longer and give you better results, especially on steel or other hard metals.

Problem: Sparks or Overheating While Cutting

If you see sparks or your oscillating tool feels hot, it could be because you’re pushing too hard or moving too fast. Instead, apply slow, steady pressure and let the blade do the work. Also, take short breaks to let the tool cool down, especially if you’re working near flammable materials.

Problem: The Oscillating Tool Isn’t Cutting Deep Enough

Sometimes the tool doesn’t cut deep. That’s okay! Just increase the speed and use a gentle rocking motion. This helps the blade dig in and gives you a straight cut with a smooth finish. Always wear your appropriate protective gear, like gloves and safety glasses, during the cutting process to stay safe.
