Did you know that you can use an angle grinder for more than just cutting materials?
Thanks to the variety of available discs, this versatile tool can help you complete a huge range of tasks.
From grinding metals and cutting granite to smoothing surfaces, you name it!
Yet if you are new to using angle grinders, the different types of angle grinder discs may be overwhelming.
The good news is that I have compiled a simple guide to various angle grinder discs and their uses.
Starting from the basic grinding discs to polishing pads, I hope this article can help you out. Let’s dive right in.
1. Grinding Discs
Grinding discs or wheels are what you use to grind a surface, remove any excess materials, or prepare metals before you weld them.
As the most popular disc type, there are also various sizes and types to choose from. This includes variety in the hardness and smoothness, which is indicated in grit.
Get a coarser grinding disc for faster results, but note they are more likely to cause sparks and a rough finish.
On the other hand, a less coarse disc can create less scratches but work slower.
2. Cut-off Discs
A cut-off disc can cut through metal materials very easily, including bars, sheets, tubes, and plates. They are much thinner than grinding discs so they can make precise cuts.
However, they are also more dangerous to work with and easy to shatter. If this happens, the shattered blades can be extremely dangerous.
So it’s important that you wear the right protective clothing when using a cut-off disc.
3. Flap Discs
The next type of angle grinder disc to know about is the flap disc.
It is quite similar to a grinding disc and comes in various grit levels, but is usually used for finishing.
These discs are generally smoother as you would use it to smooth out a surface.
Moreover, you can use flap discs to remove scratches and other defective marks on a material.
Note that working with blurred or scratch metals can be dangerous, so do wear safety gloves!
4. Wire Wheels
When it comes to removing old paint and rust from different metal surfaces, look no further than wire wheels.
This disc consists of metal wire fibers that can cause abrasion on the work surface. It also looks the most distinctive from other types of angle grinders.
Go for thick bristles that are coarser if you want to work more quickly but do not need to be precise.
For better accuracy, you should choose a wire disc with finer bristles. It’s all about adjusting to what you need.
5. Diamond Cutting Discs
If you want to work with masonry, stone, or granite, using a standard cut-off disc will not work. Instead, you need a specialized diamond cutting disc.
This disc has a diamond grits on the edge of its steel disc, making it much harder and more durable.
As diamond is among the hardest and toughest material there is, this tool can handle even the most challenging tasks. It will cut through hard metals like cheese!
Of course, diamond discs can be quite expensive, but their quality alone should be well worth it.
6. Strip Discs
Sure, a wire wheel can help you remove paint from surfaces efficiently. But did you know they can scuff up the metal that lies under the paint?
With a strip disc, you can completely prevent this accident!
Made from gentle yet firm polyfiber, strip discs can remove paint and glue from metal surfaces without damaging the metal underneath.
7. Polishing Pads
Finally, I have the polishing pads. It is a bit different because it does not cut or grind metal, but make them shine.
Polishing pads will polish any surface for a sparkling and new finish. They also come in different shapes and materials that can each create a unique look.
I would also recommend using polishing pads only if your angle grinder features speed control.
You can only polish on certain speed settings, which means not all grinders are made for the job.
These are all the most common types of angle grinder discs which you can get to suit a variety of different tasks.
Once you know what you need to do, all there is left is to choose the right disc or wheel to attach to your grinder.
It’s always useful to keep a handful of these in your toolkit too!
