Angle Grinder Blade Types and Uses

An angle grinder may be used in any trade field, including construction, metallurgy, and even woodworking. It is a far more versatile power tool than you might initially believe.

You may use them with a wide variety of angle grinders wheels and discs, including grinding wheels, cut-off discs, flap discs, and more, making them adaptable. You can do anything with these various wheels, from cutting metal sheets to scraping paint.

We'll look at the wide varieties and their applications in this article. After that, you'll know more about how each one operates and which one you'll need to complete a particular activity.

Types of Angle Grinder Blades


Due to their versatility, grinding wheels, also known as grit discs, are the most recognizable and widely used of all the discs on the market. To handle particular applications, they come in a variety of diameters up to 10 inches and with variable levels of thickness.

There are various grit levels for grinding wheels. Higher grit numbers will be less coarse than lower grit values, and vice versa. Choose a high-grit grinding wheel for a smoother finish. Low-grit grinding wheels are ideal for quick, clumsy labor where the final appearance of your item isn't as significant to you.

A grinding wheel is mainly used to remove extra material from a project's surface. You may use a grinding wheel for various tasks, such as cleaning up cuts and preparing metal for welding, making it an all-purpose disc.


Cut-off wheels serve pretty different purposes despite their similar appearance to grinding wheels. The cut-off wheels are recognizable by their thin design, which enables them to remove metal bars and sheets more precisely. Wear the appropriate safety equipment because these discs can be hazardous due to their slim design.

Different wheel thicknesses are available, and each has advantages and disadvantages. Although you can do cuts more quickly on thinner discs, they will be more brittle. A thicker disc is more durable and less likely to deform after being cut. The disc will break if it is bent in an unusual way, scattering dangerous pieces around the room.

Cut-off wheels are typically employed to slice various metal objects, such as bars, tubes, and tiny pieces of sheet metal or plates. You can also use them to shorten excessively long bolts or remove welds.


The flaps are a term for the multiple overlapping abrasive sheets that make up the disc. Although flap wheels don't look like a regular grinding wheel, it functions similarly. It distinguishes itself by giving your project a significantly more refined finish and is frequently used for finishing work. Different grit options are available, and they all follow the same principle: the more grit, the smoother the finish.

After working on a surface using a grinding wheel, you'll typically transition to a flap wheel. The revolution will continue to function at its peak until all of the grit has been removed because as the flaps deteriorate, more determination is revealed. These angle grinder wheels are frequently used in metalworking, fabrication facilities, and autobody shops. They eliminate rust, polish surfaces, and remove minor flaws like burrs or scratches.


Another effective method for removing paint from a character is to use wire wheels. Although wire wheels come in various designs and serve multiple functions, they all essentially consist of wires that protrude from a circular base.

They have bristles that are either thick, twisted, more abrasive for quicker, more accessible work, or thinner, straighter, and less abrasive for more delicate, precise work. Be careful because they can cause scratches on the surface even when used on softer materials. Various angle grinder accessories are intended to remove rust or stubborn polish metal quickly.


Diamond cutting wheels are just as durable as diamond blades and are among the most rigid blades on the market. Diamond grits are embedded in the edges. They typically last longer than conventional blades because of their rugged construction.

The disc will last longer and be more durable if the cutting rim is higher. In wet and dry cutting processes, you can utilize diamond cutting discs on some of the most complex materials, such as masonry or stone. In the vast majority of programs, you can work quickly and efficiently.


Wire wheels frequently substitute paint-stripping wheels when removing paint from metal surfaces. These wheels are often referred to as strip discs. Since they won't harm the material, they perform best when working with slightly more sensitive fabrics like soft metals, wood, or fiberglass. Strip discs are more suited to working on more delicate surfaces without endangering them because they are made of poly-fiber material. You can also use them to get rid of epoxy or other leftovers.


A grinding wheel attachment is available for polishing or removing concrete from your surface. Wheels for grinding concrete come in a variety of sizes and designs. For concrete, fiberglass and other abrasive materials are used.

Stone, masonry, granite, marble, and other complex materials can all be ground using concrete grinding wheels. These discs have a structure that makes them durable over time, but they eventually wear out, so you should replace them when they start to chip.


When using an angle grinder, always be careful to follow the correct safety precautions and wear any necessary personal protective safety equipment. The disc size and angle grinder RPM must be compatible to prevent disc damage, which could result in injuries. Every day, the leading power tool manufacturers create new safety innovations to make using your angle grinder safer for you and those around you.
