Types of Angle Grinders Wheels
A grinding wheel comprises an abrasive compound. It is used for abrasive cutting or grinding operations. They are disc-shaped and the most common types of angle grinder wheels that have ripped edges. This type of disc is built to remove rough metal edges at a fast pace. They are needed in metal fabrication jobs that require smoothening.
These angle grinder wheels have thinner sizes of about 6 mm and are used majorly for cutting metals and stones. They are cheaper and can cut at a much faster speed when compared to others on this list. They are also lightweight designs, making them a desired tool for jobs.
Diamond discs have superior power when compared to grit designs. They are more durable and are also affordable types of wheel grinders. They are safe to use for jobs as the discs are tightly fitted together.
Unlike other grinder wheels which are used for cutting and grinding, the wire wheels are used for removing paints and rust and also for polishing. They are used on hard objects to avoid breaking the materials they are used with. There are equally different types of the wire wheel, the twisted wire wheel which is the most efficient, and the cup brush which is the least effective.
They are discs used for cutting wood. As the name suggests, the limitation of this angle grinder wheel is that it cannot be used to cut any other material besides wood.
These are wheels used for cutting into round and flat metals stocks with ease. They are thinly built discs with tapered edges which enable them to slice deep into forged metals. They are tough wheels that can cut into plate metals, bolts, rebar, etc.
These discs are made of poly-fiber material. Unlike the wire wheels that scuff up an underlying surface of a material when removing paint from an object, strip discs do it better to remove epoxy, glue, and paint from a material. They are more efficient, firm, and gentle when used.
Ceramic sanding discs
These discs are the most durable designs. When talking about their functions, ceramic discs can do virtually anything that a flap disc could do(flap discs are wheels for metal finishing). There ceramic built enables them to be able to overcome any overheating during the period of use. They possess the most sanding ability than their metal counterparts. Though they are the most durable designs, they are not as popular as the rest of the designs.

1. Can a grinding wheel be used to cut metal?
You can, only that it can be a bit difficult. The reason is that the grinding wheel is designed majorly for grinding purposes and not cutting. Using grinding wheels for cutting will be difficult because the user will need more time to remove materials in a cut which often takes a long to execute.
2. How much thick metal could you cut by using an angle grinder?
An angle grinder can cut to a depth of material based on the choice of angle grinder wheel used for the job. For instance, a 230 mm angle grinder can cut to a depth of 70 mm in metals.
3. Can you use an angle grinder as a cut-off tool?
Since cut-off tools are basically for cutting purposes, angle grinders are versatile tools that can be used for a variety of operations including sharpening and cutting. So, yes, they can.
4. Can an angle grinder cut concrete?
Yes, an angle grinder can be used for cutting concrete, bricks, tiles, marble, and granite materials.
5. What difference is there between cutting and grinding wheels?
The difference between them is in the size of their thickness. A cutting wheel is thinner when compared to a grinding disc. The general thickness you’ll find for a grinding disc is a 1/4’” thickness at least.
6. Can someone use the cut-off wheel construction type on aluminum?
Yes, you can. You can use cut-off wheels such as aluminum oxide, an abrasive grain to cut metals.
7. How long do grinding wheels last?
It is recommended by Saint-Gobain that Resinoid bonded grinding wheels should be used for no longer than 2 years.
8. When should a cut wheel be replaced?
The best time to replace a cutting wheel is when the wheel’s diameter becomes too thin that you can no longer cut efficiently with it.
