Did you know it’s a great handyman tool for making difficult, intricate cuts in tile?
Tile setters use it on a job and for some, it’s their most used tool. It’s easier than dragging out a large wet-saw when you only have a few cuts to make.
Used it for cutting steel, aluminum, mortar, stucco, cement and tile. Clean rust and paint with a wire brush wheel and of course grind and polish metal using other attachments.
The one shown on this page is a 4 1/2 inch Dewalt angle grinder. Larger grinders are available but this one is used more on jobs than the large 7 inch. The job they do depends on the type of blade or wheel you put on it. If you want to grind, steel, put on a grinding wheel.
If you want to cut concrete, call me crazy… but you put a concrete cutting wheel on it. Cutting ceramic or stone tile requires a diamond blade.
You can get these tools at any large home center and all the blades and wheels that you need for the different applications. A light duty one is great for the home DIY’er and can be purchased for about $35 from Amazon.com
If your needs are more frequent or demanding for jobs like cutting tile, stucco or cement you can get a heavy duty 4 1/2 inch or a 5 inch angle-grinder. They range in price from $55 to about $130 for a professional model like a Metabo.
Angle grinders are so versatile because of the different wheels and accessories you can mount on them. I’ll only be
scratching the surface on what you can do with them here. Below is a list of uses and the wheels you’ll need to accomplish the task.
Grinding Metal,slap on a metal grinding disc. Maybe it’s time to sharpen a lawn mower blade. Sure, you could just go out and buy another one but it’s going to cost you. Especially if you’re driving around the yard on a lawn tractor with two cutting blades.
If you’re looking for a sharper edge then follow up with a mill bastard file for a sharper edge. Use the same method described above to sharpen your other edged tools.
Do you have some metal cleaning to do? A wire wheel works great for cleaning rust or paint and can fit into tight spots or crevices leaving the metal looking shiny and new.
Wire wheel or brush attachments can cost a little more (Sometimes $10-$20) but they’re great for de-burring, roughening, or rust/paint removal .
A regular cup brush provides a flexible abrasive for uneven surfaces. The brass coating, like the one shown, helps the brush run cooler and resists corrosion of the bristles.
The knotted steel wire brush will plow through your heavy duty, industrial applications like the toughest weld splatter, scale or surface corrosion. This one has heavy .020 gauge steel wires that are twisted into a tight knot to maximize the abrasive action.
When you have to Cut Steel or aluminum bars, rods or bolts, and you don’t want to spend all day with a hack-saw, you can’t beat an angle-grinder. I’ve used it to cut the re-bar inside concrete pours, angled aluminum, tube steel and rusted bolts .
A cut-off wheel is pretty cheap, about $2-$5 depending upon the quality. The higher the price usually means it will last a little longer.
When it comes to cutting stone, concrete, mortar, or making intricate cuts in tile nothing beats an angle-grinder. If you have to cut a circle in tile all you have to do is score a line using a diamond blade then make a series of straight cuts towards the score line and break the tile off.
If you’ve got a lot of tuck pointing to do, it’s worth buying one just to remove the old mortar. The diamond blades used to remove old mortar from in between brick or block is called a Tuck Point wheels. The look like regular diamond wheels except that they are segmented and thicker… a least a 1/4 inch thick.
These wheels aren’t cheap either ($25 – $125). You’re going to be producing heavy dust so wear a good dust mask and a face shield… Oh yea, you might want to close you windows too.
