Can You Use Angle Grinder to Cut Metal?

“Can you use an angleAngle Grinders to Cut Metal?” is a question that pops up frequently on the appropriate message boards. What’s the quick and easy answer? Absolutely!  Indeed, among the many hand-held equipment available, the angle grinder appears to be the most flexible of metalworking power tools.  That’s why it’s no surprise that this specific item is utilized by a variety of crafts, including those in the automotive sector, HVAC, plumbing, and a variety of others.

Grinders are often used for refurbishing and polishing metal materials, so it shouldn’t come as a surprise that you can use them on stainless steel surfaces if you have the correct disc.

You shouldn’t, however, go into the process without taking any safeguards. That’s why, throughout the post, we’ve included a few safety guidelines to assist you learn how to use angle grinder to cut metal in the most efficient and effective way possible.

How to Use an Angle Grinder to Cut Metal

Now that we’ve established the notion of using an angle grinders to Cut Metal, let’s examine what the optimum way of operating an angle grinder to cut metal. We must point out that the method is not always the same because different angle grinder models work in different ways. Even yet, the safety measures you must follow while cutting metal or steel are very similar.

What is the maximum thickness of steel when operating an angle grinder to cut metal?

It truly relies on the angle grinder’s cutting capacity as well as the size and type of disc you’re using. Apart from that, the thickness of the material you’ll be cutting is a determinant in determining the steel’s possible cutting depth.

Not only that, but cutting discs come in a variety of thicknesses, so you’ll need to pick the proper one.

But let’s pretend you’re using a 4-1/2-inch grinder with a flat diamond cutoff blade to cut stainless or mild steel, as most people do. A 1mm or 1.6mm iron-free disc should be used to cut the stainless steel.

When cutting thin metal materials like sheet metal, a 1.0mm or 0.8mm cutting disc is recommended. Due to the reduced blade thickness that results in less heat transmission, any of these discs will provide a cleaner appearing cut and minimize any potential discoloration.

When cutting or buffing metal or aluminum with an angle grinder, using a type saw lubrication will extend the disc’s life and prevent the risk of chipping.

If you’re going to chop thicker, heavier steel like rebar or structural steel like angle iron, you’ll need a cutting disc with a thickness of 1.6mm or 2.5mm. Using a bigger blade, such as a 2.5mm cutting disc, to cut through dense steel has certain disadvantages.

Due to the slower blade speed of the bigger disc-equipped, the completed cut of your steel workpiece may show evidence of discoloration. What is the reason behind this? Because of the increase in friction, essentially.

You could always use another power tool to cut metal, depending on how thick the material is and how clean of a cut you want.

While accuracy and elegance are required when cutting thick, dense steel, a metal cutting circular saw or a metal chop saw are two of the most common suspects. Break out the trusty grinder if all you want to do is make short cuts when accuracy and overall aesthetics are secondary concerns. Simply use the suggested CDs whenever possible.

Follow these guidelines to avoid eye injuries, wounds, burns, and other problems when cutting metal: • Read and follow all safety warnings on metal-cutting discs and blades. • Protect your eyes and ears with safety glasses, a face shield, and hearing protection. • Wear gloves, a long-sleeve shirt, and slacks to protect any exposed skin.

• Let newly cut metal cool completely before handling it.

• When working with metal that may have sharp edges, use gloves.

• Before cutting metal, secure it with a clamp. • If you’re use angle grinder to cut metal, don’t let anyone close you unless they’re wearing hearing and eye protection.

Suggested disc types.

You can use angle grinder to cut metal and all types of it, including bolts, angle iron, rebar, and even sheet metal, when it’s equipped with an abrasive metal-cutting disc. However, as you use the discs, they wear down fast, cut slowly, and reduce in diameter. Instead, we recommend utilizing a diamond blade with a ferrous metal cutting rating. These will last far longer than abrasive discs, cut quicker and cleaner, and wear down much slower.

The Disc Type	Application	Consideration
Metal cutting disc / cut off disc	Most metals can be cut. It can’t be used to grind anything. Present at a 90-degree angle to the workpiece	Aluminium Oxide is used to make the cutting edge
Grinding disc	Metals, both ferrous and non-ferrous, are ground. Present at a 45-degree angle to the workpiece.	Aluminium Oxide is used to make the cutting edge.
Multi-cut cutting disc	Metals, both ferrous and non-ferrous, are cut through (including stainless steel). For more sophisticated cutting needs, it will also cut through brick, stone, contemporary composites, and tiles.
Stainless steel cutting disc	Steel and stainless steel are cut through. It’s especially handy for cross-sections with tiny cross-sections.
All cut diamond blade	Cast iron, various ferrous and non-ferrous metals, and most building materials are all cuttable.	Cutting edge with diamond grains attached to it.
Abrasive grit mop disc	Metal grinding in general, especially for edge grinding jobs like deburring, sharpening, and surface finishing.	Grinding flaps in a fan-shaped radial pattern.
Slitting disc / thin cutting disc	Pipes and profiles with thin walls are cut. This tool creates a fine cut line. Use on ferrous and non-ferrous metals, as well as stainless steel.	Thin cutting discs produce less heat during operation, cause less tool vibration, finish cuts faster, and waste less metal in each cut, saving up to 2 mm each cut.
