Overview of angle grinders
Angle grinder tool
Angle grinders use a wide variety of cutting and grinding wheels, like the diamond cycle shown here.
Yous'll find angle grinders anywhere power tools are sold. Larger mitt grinders are bachelor, but the popular 4-in. and four-1/two in. grinders are the correct size for about tasks. You can buy very cheap bending grinder tool, but for frequent use or for demanding jobs like cut stucco or cement, I'd recommend spending a little more for a grinder with a more powerful motor (look for a motor that draws five to 9 amps).
The ability to handle different wheels and accessories is what makes angle grinders and then versatile. Your angle grinder includes a spindle washer and spindle nut that you'll install in different configurations to accommodate thicker or thinner wheels or remove altogether when you screw wire wheels and cups onto the threaded spindle. Consult your manual for instructions on mounting wheels and accessories.
Y'all'll find abrasive wheels for an angular grinder in any hardware shop or domicile center. Although the wheels all look similar, they're designed for unlike tasks. Read the labels.
Metal cleaning
Photograph 1: Apply a wire brush for cleaning
Clean rust and caked-on cement and dirt from garden tools with a wire cup. Secure the work with clamps or a vise. Make sure the brush is spinning away from, not into, the border. Otherwise, the castor tin grab on the border and cause the grinder to kick dorsum at yous.
Photo 2: Paint removal
Remove paint with a wire wheel. Again, be careful to work away from, non into, precipitous edges. Wire wheels fit into crevices and tight areas.

Wire wheels remove rust and flaking paint quickly. Wire wheel and brush angle grinder attachments are designed for different types of stripping, cleaning and deburring tasks. Wire cup brushes work best for stripping paint or rust from broad, flat areas. Wire wheels fit into crevices and corners more than easily. Wheel and castor attachments come in a broad diversity of styles. Read the packaging to notice one that works for your application. Also, make sure to friction match the threads to the spindle threads on your grinder. Most bending grinders have 5/eight-in. spindle threads, but in that location are a few oddballs.
Cutting confined, rods and bolts
Photo 3: How to cut rebar
Mount a metallic cutoff cycle in your angle grinder. Prop upwardly the long side of the rebar and hold information technology securely. Drop the cutoff wheel through the metallic, allowing the weight of the tool to do most of the work. Permit the short end to drop freely to avoid binding the blade.
Photo 4: Cut frozen bolts
Grind bolts flush to physical. You tin can brush against the physical, merely don't try to cut into information technology with this wheel.
Metallic cutoff cycle
Use an inexpensive metal-cutting blade for rough cutting metal.
If y'all're patient, you can cut most metallic with a hacksaw. Merely for quick, crude cuts, it's difficult to trounce a grinder. I've used an angle grinder to cutting rebar (Photo 3), angle atomic number 26, rusted bolts (Photo 4) and welded wire fencing. Use an inexpensive cutoff cycle for these and other metal-cutting tasks.
Cut tile, stone and concrete
Photograph v: Score the tile face
Mark the outline of the cutting accurately on both the front and the back of the tile. Clamp the tile to your workbench and score the outline near 1/8 in. deep on the front with the diamond blade.
Photo 6: Finish the cut on the back
Flip the tile over and cut through the tile from the dorsum. Extend the cuts slightly past the lines at the corners to make crisp, square corners.
Dry out-cut diamond bike

Notching and cut ceramic or stone tile to fit around outlets and other obstructions are hard if not impossible with standard tile cutters. But an angle grinder fitted with a dry-cut diamond bike makes short work of these difficult cuts.
Restore cutting edges
Photo 7: Sharpen blades
Clench the blade in a vise or to your workbench with hand clamps. Orient the grinder and adjust the blade guard to deflect sparks from your face and body. Align the grinding wheel with the angle on the bract. First the grinder and movement the grinding wheel steadily beyond the blade while applying lite pressure.
Grinding cycle
Use a grinding wheel for general sharpening tasks.
Outfitted with a grinding bicycle, an angle grinder is a great tool for restoring edges on band-aid tools like hoes, shovels and ice scrapers or for the initial grinding of axes, hatchets and backyard mower blades. If you demand a sharper edge than the grinder leaves, follow up with a factory bastard file. Photograph 7 shows how to sharpen a backyard mower blade. Utilize the same technique to restore the border on other tools. Orient the grinder so that the bicycle spins from the trunk of the blade toward the edge (refer to the arrow on the body of the grinder to determine which direction the cycle spins).
Finally, with the grinder off, rest the grinding wheel confronting the blade and suit the bending of the grinder to lucifer the blade's bevel. This is the position y'all'll want to maintain equally yous grind the border. Elevator the grinder from the border, switch information technology on and allow it come up to speed before moving information technology into the blade.
Stroke the grinder across the piece of work in the direction of the handle rather than grinding dorsum and forth. Then lift information technology off and repeat, concentrating on holding the grinder at a consistent angle throughout the stroke.
Information technology's easy to overheat a metal blade with a grinder. Overheated metal turns a blue black or straw color and won't stay precipitous for long. To avoid overheating, apply but light pressure and continue the grinder moving. Besides, go along a bucket of h2o and sponge or rag handy and drench the metal frequently to continue it absurd.
Cutting out old mortar
Photograph 8: Grind mortar
Grind out old, loose mortar with an angle grinder and diamond tuckpointing wheel. Make two or three one/two-in. deep passes to completely clear the articulation. Stay most ane/8 in. from the brick to avoid damaging it.

Make clean out old mortar joints with a tuckpointing cycle.
Grinding beats a chisel and a hammer for removing onetime mortar. It would be worth ownership a grinder but to remove mortar if yous had a lot of tuckpointing to do. Thicker diamond tuckpointing wheels remove old mortar quickly without disturbing or damaging the bricks. Information technology's dusty, though, so wear a dust mask and make sure to close your windows and warn the neighbors.
We've but touched on the jobs you can exercise with an angle grinder. Browse your local hardware shop or home centre to get a better thought of the angle grinder attachments available. They can save you a ton of time.
Grinder Safety
Different drill motors that run at well-nigh 700 to i,200 rpm, grinders spin at a breakneck speed of 10,000 to 11,000 rpm. They're fast enough to exist scary! Follow these precautions for condom grinder apply:
- Wear a face shield and gloves.
- Unplug the grinder when you're irresolute wheels.
- Attach the handle and maintain a house grip with both hands.
- Employ the guard if possible.
- Run new wheels for one minute in a protected area before using them to brand sure the wheel isn't defective.
- Orient the work so droppings is directed downwardly.
- Keep bystanders away. Everyone in the vicinity should clothing safety glasses.
- Orient the piece of work so the wheel spins abroad from, not into, sharp edges. Wheels, especially wire wheels, can catch on an edge and throw the workpiece or crusade the grinder to kick back (Photograph one).
- Keep sparks away from flammable materials.
- Clamp or secure the workpiece in some fashion.
- Shop angle grinders out of children's achieve.
