What is Cutting Wheel for Grinder?
Before we get into a wheel for an angle grinder, let’s learn what an angle grinder is.
An angle grinder is an authoritative tool for grinding, cutting, polishing, etc. It is a handheld power tool that supplies immense power and speed to rotate the wheels or discs. These discs are attached or detached according to your need.
Several options for wheels or discs are available in the market. The design, structure, or material can change depending on its purpose.
The discs we cut metals are generally called cutting discs or wheels. Cutting discs can also come in different shapes or forms. However, these are solid and sturdy circular discs with tapered edges to provide a smooth cut for metals.
Types of Angle Grinder Discs or Wheels
An angle grinder is a multi-purpose power tool. Depending on what type of wheel you are inserting, the outcome changes. This quality makes it an essential tool for many construction workers.
In general, you can find 10 types of angle grinder discs or wheels. Each one serves a different purpose. Let’s look into the kinds of discs for angle grinders.
1. Cut-off Wheels
Cut-off wheels are also known as parting wheels. These are thin, tapered circular discs that cut metal surfaces. You can find various thicknesses among cut-off wheels.
While more delicate discs make the quicker cut but tend to break, thicker discs cut slower.
2. Diamond Cutting Discs
If you want superb cutting discs that effortlessly cut sturdy metals or stones, then diamond cutting discs are the way.
Diamond grits are included in the grits, providing more cutting strength than cut-off wheels. With power, it comes with better durability as well.
3. Grinding Discs
As the name suggests, grinding discs are used for grinding. You can grind metal or stones with grinding wheels.
Several grinding discs are available in the market; some have higher grit for the more refined finish, while others have low grit for the coarse finish.
4. Flap Discs
Flap discs use for sanding down and smoothing out surfaces. These discs have abrasive surfaces, usually containing aluminum oxide. They are similar to grinding discs but more abrasive.
While grinding discs have a single abrasive surface, flap discs overlap several sheet-like pieces. These small abrasive sheets are called flaps and, hence, flap discs.
5. Wire Discs
Wire discs or wheels have a lot of wires connected in a circular formation. Some types have twisted wires, while others are straightly attached to the head. Depending on the outcome you want, you can choose any of these two.
The purpose of wire discs can be similar to grinding discs. However, these are harsher and stronger on the surface. You can use a wire disc to remove rust or paint from a metal surface. These wheels can leave scratches or marks on delicate metal surfaces.
6. Paint Stripping Discs
Paint stripping discs can remove paint from different surfaces. These discs are good for wood or soft metal surfaces, but they are also suitable for metal surfaces, as you can use them for car paint removal. So if sometimes you don’t have sanders for car paint removal, these Stripping Discs can be a quick fix.
Although wire discs can also do this job, they can be too harsh on the surface and damage it.
The discs of paint striping wheels are like a cushion layer made of poly fiber material. It is like grit and fiber, which removes paint effectively without damaging delicate surfaces.
7. Concrete Grinding Discs
Concrete grinding discs are structurally different than general grinding discs for apparent reasons. These discs are meant to smooth down concrete surfaces. These discs can also grindstones, granite, marble, bricks, etc.
Concrete grinding discs have significant patterns on the discs, which helps to polish sturdy materials like concrete. These are made of abrasive materials and are also incorporated with fiberglass.
8. Polishing Pads
You can use specific discs to polish surfaces and enhance their beauty. Polishing pads or buffing pads help to polish different surfaces.
These discs usually come with soft materials based on their purpose. You can use polishing pads to polish stainless steel, glass, cars, wooden furniture, etc.
9. Wood Cutting Discs
Some cut-off wheels are capable of cutting wood. However, if you are looking for a disc dedicated to cutting wood efficiently, it is better to use a wood-cutting disc. These wheels are ideal for cutting both hard and soft.
The formation of wood-cutting discs can be slightly different from metal cutting wheels. Wood-cutting wheels may have toothed blades similar to saws. Moreover, the tips of the blades can contain carbide, which provides incredible strength for cutting woods effortlessly.
10. Wood Carving Discs
Tood carving discs are perfect for serving the purpose of efficiently and effortlessly carving woods. Wood is a sturdy material, and it requires power to cut it. Hence, like wood cutting discs, wood carving blades are also incorporated with carbide.
Wood carving discs also have a toothed surface. However, they are a lot in number compared to wood-cutting discs. These discs have many small sharp spikes to provide precision and a smoother finish.
Note: Although die grinders are not used for wood carving, sometimes it brings a more professional finish than an angle grinder. We covered the subject in another article; see if you want to know what are the good Die Grinders for Wood Craving and other polishing, grinding, etc., projects.

Why You Need an Angle Grinder Wheel?
Having an angle grinder wheel that suits your necessities is probably any welder’s dream. However, only having the angle grinder is not enough for a top-notch job.
An appropriate angle grinder wheel is also necessary. Otherwise, the cutting job can look sloppy even after having an excellent angle grinder.
This is more vital for cutting metals as a tiny error can ruin the entire project. Hence, choosing the best grinder wheel is the key to finishing off an excellent metal construction project.
It improves your performance and keeps you safe from unwanted injuries.
How to Choose the Right Cut-Off Wheel? [Buying Guide]
Before purchasing any cutting wheel for your grinder, you need to consider some essential things. Unless the discs are compatible with your machine and suitable for your job, they would be useless. So, here are the topics that you should keep in mind.
a. First Thing First, Consider the Disc Size
The first thing that you need to keep in mind is the size of the disc. By size, we actually mean the diameter of the cutting discs.
A few options are available, such as 3 inches, 4 inches, 4.5 inches, or 6 inches. Depending on your angle grinder, you need to choose the compatible size. For instance, a 4.5 inches angle grinder will not work with a 6 inches disc or a 3 inches disc.
A head-up just in case you have not purchased your angle grinder. More oversized discs can cut larger pieces of metal and might take less time. On the other hand, smaller discs or grinders are better for smaller or detailed work.
b. Consider the Disc Thickness for a Perfect Cutting Wheel
Disc thickness makes or breaks it quite literally. There is a fine line between too thin or thick and perfect thickness cutting wheels. Thin blades tend to provide precision, clean-cut and minimal wastage. However, they are more prone to breaking, obviously for being lean. They are more fragile and risk shattering, chipping, and whatnot.
On the opposite spectrum, thicker discs work slower. Being sturdy, you get less flexibility and precision. Wastage could be higher compared to thinner blades. So, finding out which one works best for you can be pretty challenging. You might have to go through trial and error before finding the perfect cutting wheel for your machine.
c. Observe the Disc Material to Ensure a Good Quality
Disc material is essential for the vulnerability of the discs. Usually, the cutting wheels are of a combination of elements. They can have aluminum oxide, fiberglass shes, other harsh elements like diamonds that ensure a smooth and clean cut. Without good material, the cutting job can become tiresome. The metals might not cut properly, can make a lot of waste, can damage the metals, or the discs can break too.
Choosing a cutting wheel with great material is the key to longevity and durability. So far, aluminum oxide cutting discs are best for cutting any metals. Sometimes discs infused with diamonds work even better for more vital metals.
d. Check Out the RPM Rate (Rotation Per Minute)
RPM stands for Rotation Per Minute. This indicated how fast the cutting wheel could rotate.
Faster wheels increase more advanced cutting capability. Above that, it reduces working time. These two qualities are essential for any extensive or professional metal cutting work.
Then again, smaller discs tend to have more RPM for apparent reasons, and larger blades are slower. However, keep in mind that the cutting wheel you choose has an RPM of no lower than 3900. In that case, the cutting wheel might not even be able to cut through metal.
e. If You Own A Large Project, Buy A Pack Of Discs
In general, cutting discs or cutting wheels come in numbers. Usually, you will find that they come in packages of 5, 10, 20, or 25 pieces. Having more discs is excellent for larger projects and having spare for an emergency.
As cutting metal is a tough job, and these discs are not immune to breaking, having a little more discs do not harm.
However, if you are cutting metal as a one-time job or for hobbies, you might not need a pack of 25 discs. That would waste both your money and space. You can opt for more miniature packs or single discs in situations like that.
Then again, some cutting wheels are so strong that they do not come in packages as these are strong enough to complete a job by themselves, such as diamond cutting wheels.
How many discs you want to buy is totally up to you. However, we would suggest you can purchase only a few spare pieces as a backup.
f. Consider The Price of the Product According To Your Budget
Every good thing comes at a price. It is impossible to buy something that exceeds your budget and breaks the bank. There are many options for cutting wheels for angle grinders at different price points.
You can choose a cutting wheel based on your budget. With that being said, good quality mostly comes with a higher price. So, for better quality, you might have to invest a little more. However, for home projects, affordable cutting wheels work just fine.
