Angle grinders use a wide variety of cutting and grinding wheels. A small angle grinder, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing. Angle grinders can be powered by an electric motor, petrol engine or compressed air.
You’ll find angle grinders anywhere power tools are sold. Larger hand grinders are also available, but the small angle grinders are the right size for most tasks. You can buy very inexpensive angle grinder tool, but for frequent use or for demanding jobs like cutting stucco or cement, you can always go for small angle grinder on Xtreme Polishing Systems.
The ability to handle different wheels and accessories is what makes angle grinders so 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 removes altogether when you screw wire wheels and cups onto the threaded spindle.
- Metal 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 edge.Wire wheels remove rust and flaking paint quickly. Remove paint with a wire wheel. Again, be careful to work away from, not into, sharp edges. Wire wheels fit intocrevices and tight areas.Wire wheel and brush 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 easily. Wheel and brush attachments come in a wide variety of styles.
- Metal Cutting & Grinding: A metal cutoff wheel uses aluminum oxide as an abrasive to cut rebar, rusted bolts, and iron fencing. Mount a metal cutoff wheel in your angle grinder. Prop up the long side of the rebar and hold it securely. Drop the cutoff wheel through the metal, allowing the weight of the tool to do most of the work. Allow the short end to drop freely to avoid binding the blade.
- Tile, Stone, and Concrete Cutting:Mark the outline of the cut accurately on both the front and the back of the tile. Deep on the front with the diamond blade. Notching and cutting ceramic or stone tile to fit around outlets and other obstructions is difficult if not impossible with standard tile cutters. But an angle grinder fitted with a dry-cut diamond wheel makes short work of these difficult cuts.
- Restoring Metal Edges:Outfitted with a grinding wheel, a small angle grinder is a great tool for restoring edges on rough-and-tumble tools like hoes, shovels and ice scrapers or for the initial grinding of axes, hatchets and lawn mower blades. If you need a sharper edge than the grinder leaves, follow up with a mill bastard file. Stroke the grinder across the work in the direction of the handle rather than grinding back and forth. Then lift it off and repeat, concentrating on holding the grinder at a consistent angle throughout the stroke. It’s easy to overheat a metal blade with a grinder. Overheated metal turns a bluish black or straw color and won’t stay sharp for long. To avoid overheating, apply only light pressure and keep the grinder moving.
- Grinding Mortar:Grinding beats a chisel and hammer for removing old mortar. It would be worth buying a grinder just to remove mortar if you had a lot of tuck pointing to do. Thicker diamond tuck pointing wheels remove old mortar quickly without disturbing or damaging the bricks. It’s dusty, though, so wear a dust mask and make sure to shut your windows and warn the neighbors.We’ve touched on the jobs you can do with a small angle grinder.
