What Can You Do with an Angle Grinder?

A grinder tool is popularly referred to as a welder’s best friend because the uses of an angle grinder go far beyond simply cutting and grinding. Since grinding and cutting are the most popular uses for an angle grinder tool, let’s take a look at exactly what angle grinder cutting and grinding is.

Cutting

While tile cutters are great for cutting across stone or ceramic tiles, you may find it difficult to cut straight edges. You may find it difficult to make precise cuts while using a tile cutter; fortunately, an angle grinder makes it easier for people to perform these tasks without worrying about slip-ups or accidents.

The grinding discs used for severing are called cut-off discs; they come in different thicknesses but are much thinner than a grinding disc. The process is straightforward: you turn the grinder on and press the spinning abrasive disc into the material you’re cutting from its end first, not the front face like a grinding disc.

As it spins with force pressed against the material, it slices a thin gouge out of the metal, old mortar, or other material and will continue as you put pressure on it until your gouge is complete and the material is severed. Depending on how much weight you put onto the disc will determine how fast you cut, but if you put too much pressure on, the disc can bend and break due to its thin structure.

With the right set of discs, you can conveniently use your angle grinder to restore round edges of countless household tools, such as shovels, blades, axes, and lawnmower blades. You may refine the finish by using a mild file at the end.

When using grinder tools for cutting, a cut diamond grinding wheel can be used in conjunction with a cut diamond disc to use an angle grinder for thicker structures such as old mortar that will not typically respond to a wire wheel or less sharp grinding wheel.

Sharpening

Apart from mere polishing and cutting tasks, you can also use angle grinders to sharpen home and garden tools. You can use the tool to sharpen the edges of not only common household implements, such as lawnmower blades, axes and hatchets but also other low-key tools, such as ice scrapers, hoes, and shovels.

When performing these tasks, ensure the blades are tightly clamped to a worktable before starting the sharpening project; not following the instructions properly can lead to dangerous outcomes.

Grinding

As the name might suggest, the primary purpose for angle grinders is for grinding surfaces. You can use an angle grinder on virtually any type of material due to the range and power of the different types of discs and wire wheel selections available to penetrate the material and smooth and polish the surface to your preferred dimensions.

When one of these discs is attached, regardless of the material you’re grinding, you turn the tool on and press the front face of the spinning abrasive attachment onto the surface. Whether your projects need flattening, smoothed off, or completely removed you press the disc onto it with pressure in a circling or oscillating motion.

The materials most commonly ground are types of metal like steel, aluminum, and stainless steel. Concrete is another common material that diamond inserted discs chew through quickly. It’s recommended to wear a dust mask or face shield with any concrete work and use a stream of water on it, so you don’t breathe in a cloud of dust.

As you can see, angle grinders are versatile tools that can be used to cut thick material or polish a stubborn edge on some of the most impenetrable materials on earth–but a certain degree of caution is needed when using angle grinders to avoid injury and to work without damaging the tool.

How Dangerous Are Angle Grinders?

It is essential you familiarize yourself with appropriate safety precautions before using angle grinders. Make sure you know exactly how to hold and position the grinder to avoid slippage and possible severe injury.

The power and speed at which the wheel and disc turns is enough to easily severe a hand or limb, therefore you need to make sure the material is firmly in place. Make sure to attach or clamp the stone/tile to a workbench; not clamping the stone tile properly can cause it to slip during the process, potentially causing an injury.

This can also cause the tile to slip from the place, potentially ruining it. For added safety and comfort, it is best you opt for a grinder with additional features such as an eye shield, that will prevent flying debris from penetrating your eyes.

Also, ensure you know how to use the machine properly before actually setting it up, always maintain a firm grip on the grinder, and make sure the blades are spinning away and towards the edge from you when using angle grinders.

Frequently Asked Questions

Can You Use an Angle Grinder to Cut Wood?

Angle grinders can be used to cut wood, but this is a potentially dangerous task since the power of these tools meant to polish and grind an edge on much thicker types of material. An Angle grinder disc usually spins at between 10,000-20,000 RPM (revolutions per minute) which is just too powerful to freely use for a material like wood which would disintegrate before your very eyes.

Consider purchasing a tool from your hardware store that is specially made for cutting wood, such as a saw.

Can An Angle Grinder Be Used as a Sander?

Angle grinders work well if you need to use the tools for sanding. Be sure to purchase a flap disc that has sandpaper on the outer layers to ensure your grinder performs sanding in lieu of grinding.

Be sure to move the grinder along the surface in a circular motion without too much pressure to ensure no possible damage is applied to the surface.

Final Thoughts

An angle grinder provides a great way to work with stubborn materials that do not respond to traditional cutting or edging methods. The right tool will help you perform a variety of grinding, cutting, and polishing jobs with ease.

Opt for a versatile machine that features multiple attachments and accessories. This will allow you to perform a variety of jobs with minimal efforts.

The ideal angle grinder is not only able to sharpen and grind objects efficiently but is also lightweight and not too bulky, which offers you maximum control when using one of the most powerful tools in the hardware market.
