Clamp down the item you're working on so it doesn't move around. When applying the wire brush to the edge of something, position the angle grinder so the brush spins away from the object you're grinding rather than into it.  Try buzzing off dirt that's set on garden tools. It will even work on set-on cement. Pick the cup wire attachment for flat surfaces and the wheel to get into crevices. A cutting wheel works much like a saw. You press it lightly on the object you want to slice through, and it will make short work of things like metal rebar and tile.  Make sure to pick the right type of blade for the project you're working on. For metal, a cutoff wheel works well, and it's fairly cheap. For masonry, tile, and concrete, choose a diamond wheel. Read the attachment to know what materials you can use the wheel on. If you have loose mortar in your brickwork that you need to replace, use this wheel to do the job. Run the wheel between the bricks, making several passes to get it all out. Try not to get closer to the brick with the tool than 1⁄8 inch (3.2 mm). Pick a tuckpointing wheel that's about the width of your mortar to make the job go faster. Metal tools get dull from time to time, including things like ice scrapers, lawn mower blades, hoes, and hatchets. Press a grinding wheel up against the edge with the grinder off, positioning it perpendicular to the blade. Adjust the grinding wheel so that it's at the same angle as the edge of the blade and the wheel will turn away from the edge rather than towards it. Lift the wheel off for a moment. Turn the grinder on and make several light passes along the blade, following the correct angle.  Don't let the blade get too hot, as it will become very brittle. If it turns black or blue, give it a rest for a moment. Check the wheel for the arrow showing you which direction it will rotate when on.
