What are Angle Grinders Used For ?

Cutting Bars and Rods

You should mount a metal cutoff wheel in your angle grinder. It’s generally inexpensive and does well when it comes to cutting rough metals.

You should prop up the long side of the rebar and make sure it’s securely held. Then, you drop the cutoff wheel through the metal, using the weight of the grinder to exert the effort.

Finally, the short end should be left to drop freely so that you don’t bind the blade.

With patience, you can cut pretty much any kind of metal.

Cutting Tiles and Concrete

You should begin by marking the outline of the cut accurately on both the front and the back of the tile.

Securely position the tile, then score the outline about 1/8-inches deep on the front using a diamond blade.

Next, you flip the tile over and cut it from the back. If you want perfectly square corners, you should slightly extend the cuts past the lines.

Cleaning Metals

You should use a wire brush to clean larger, flat areas. If you want to clean in between tighter spaces, you should go for a wire wheel.

To clean rust, cement, and dirt from your metal tools you should secure the thing you’re working on with clamps or a vise.

As you work, make sure that the brush is spinning away from the edge and not into it. Otherwise, the grinder might kick back due to the brush catching on the edge.

Depending on the stripping, cleaning, or deburring task you’re doing, your choice of a wire wheel and brush attachments.

Sharpening Blades and Tools

You should clamp the blade in a vise or to a workbench. Direct the grinder and adjust the blade guard to deflect the sparks from your body and face.

Make sure the grinding wheel is aligned with the angle on the blade.

Finally, start the grinder and move the wheel steadily across the blade as you apply some light pressure.

You should make sure that you’re stroking the grinder across your work in the direction of the handle and not grinding back and forth.

If you overheat your metals, they turn a bluish black color and don’t stay sharp long after. To avoid that, only apply light pressure and keep the grinder in motion.
You can even keep a bucket of water and a sponge nearby to cool your metal down manually every now and then.

Grinding Mortar

An angle grinder and a diamond tuckpointing wheel are the 2 things you need to grind old and loose mortar.

You should make a few half-inch deep passes to clear the joint and stay around 1/8 inches away from the brick lest you damage it.

Now, these are just a couple of things you can use your grinder for.

There are so many ways you can make use of your grinder, so don’t hesitate to ask a local hardware store or home center.
