Can an angle grinder cut wood? My honest test

It was a hot Tuesday. I was tired.

I had a simple job to do. I needed to cut one piece of wood. It was just a small 2×4.

My Stihl MS 250 chainsaw was in the shed. It was far away. I felt lazy. I did not want to walk over there. I did not want to mix the gas.

I looked at my workbench. I saw my angle grinder. It was plugged in. It looked ready.

“Can an angle grinder cut wood?” I thought.

I made a bad choice. I picked it up. That choice almost sent me to the hospital.

The Problem: It Is Too Fast

I held the grinder. I touched the wood.

Smoke came up instantly. It smelled bad. It did not smell like fresh sawdust. It smelled like burning.

Then, the tool jumped.

It is called “kickback.” The grinder jerked out of the wood. It flew back at my chest. My heart pounded. I dropped the tool. It bounced on the ground near my feet. The blade was still spinning.

I was shaking. I got lucky. I still had all my fingers.

The Explanation: Why It Is Dangerous

Why did this happen? I know tools. I know how to run a chainsaw. Why did this tool fail?

It is simple math.

1. The Speed is Wrong

• Circular Saws spin slow (about 5,000 RPM).
• Angle Grinders spin fast (about 12,000 RPM).

Wood is soft. But 12,000 RPM is too fast. It burns the wood. The blade gets stuck. When it gets stuck, the energy kicks back at you.

2. No Control

A circular saw has a flat metal shoe. It rests on the wood. It keeps the cut straight.

An grinder has no shoe. You hold it in the air. If your hand shakes, the blade twists. A twisted blade bites the wood. Then it jumps.

3. The Wrong Blade

I used an old abrasive disc. It was for metal, not wood.

Some people buy “chainsaw discs” for grinders. Do not do this. They are very dangerous. A chainsaw has a brake. A grinder does not. If a chainsaw disc kicks back, it will cut you badly.

The Fix: How to Do It Safely

If you must use a grinder, you need the right gear. Do not use a saw blade. Do not use a metal disc.

Step 1: Buy a Carbide Grit Disc

Go to the store. Look for a “Carbide Tungsten Grit” disc.

It has no teeth. It looks like rough sandpaper made of metal.

• It grinds the wood.
• It does not grab or snag.
• It is much safer.

Step 2: Wear Your Gear

Put on a face shield. Wood chips fly fast. Glasses are not enough. Wear thick leather gloves.

Step 3: Clamp It Down

Use two hands on the grinder. You cannot hold the wood. Clamp the wood to a table.

The Better Way: Use the Right Tool

I learned my lesson. Now, I use the right tool.

My Stihl stays in the woods. My grinder stays on metal. For small wood cuts, I found a better tool.

The Oscillating Multi-Tool

This tool is great. It vibrates fast. It does not spin. It is safe. It makes clean cuts in tight spots. It will not kick back.

Final Thoughts

So, can an angle grinder cut wood?

Yes. But it is risky.

That Tuesday scared me. I respect the speed of the tool now.

If you need to shape a log, use a Carbide Grit disc. It works like a strong sander.

But if you need to cut a board? Go get the saw. Do not be lazy like I was.

Stay safe. Keep your guards on.
