In simple terms, an angle grinder is a handheld power tool with a gyratory disc that’s primarily used for polishing and grinding. As the name suggests, angle grinder is only a small piece of tool that belongs to a much bigger grinder family, such things like weed grinder, wire wheel grinder, wire brush grinder, cylindrical grinder and surface grinder. As for the other one, wire wheel, is a mechanical wheel that equipped on the grinder machine. The name angle grinder originates from the design of these tools, as they feature a cutting head that’s placed at an angle relative to the drive shaft. An angle grinder can be powered by one of three power sources: compressed air, petrol, and electricity and it can be either cordless or corded.
Angle grinders come in distinct shapes and sizes, but the most commonly utilized objects are 4 and 4.5-inch grinders. That’s why you will see some discs of those sizes at any hardware store. Cutting attachments are equally manifold, and as of now, there’s just about a myriad attachment for each purpose, such as: diamond tuck-pointing disc, grinding discs, wire cup brushes, wire discs, metal cut-off discs, and dry-cut diamond discs. Based on the object you’re trying to cut or finish, you can pick a different motor, size, and model. For example, if you need to cut masonry or another hard-rock material, you should definitely get an angle grinder that has a powerful drive motor, ideally one that’s five to seven amps.
Wire wheel brushes come in different kind of wire configurations and to be mounted on power grinders, such as angle grinders and bench grinders. Think about using a crimped wire wheel when you need a pliable wire wheel for light to heavy jobs and crooked surfaces, or a stringer bead wire wheel when you have a tough undertaking like cleaning welds. For cleaning joints or cracks in concrete and asphalt, expansion joint wire wheels are your best option when used with a walk-behind street saw. Carbon steel wire wheels are the most ordinary type material and utilized for general purpose and several applications.
Wire wheels and wire brushes are the common tools used for cleaning and surface preparation in welding applications. These are the optimal choice for weld cleaning, when it is imperative to remove spatter and other contaminants previous to finish or the next weld pass. The tips of wire brushes do the work, functioning like tiny hammers hitting and preparing the work surface is essential, so don’t forget this. Applying the adequate pressure is key to power brush performance, as exceeding pressure flexes and bends the wires, preventing the tips from working. This can result in premature wire breakage and dramatically diminish brush life. Power brushes offer the speed and efficiency indispensable to complete cleaning and surface preparation applications swiftly and efficiently. When you are removing coating from a surface, such as rubber, paint, or epoxy coated abrasives have an inclination to load; that is to say, the material being got rid of packs between the grains and builds up, and thus stopping their ability to perform. A power brush’s ability to “self-clean” makes it the No.1 choice for these cleaning applications.
It's the most multifaceted tool in the box and should be a staple of any shed or workshop but we aren't just talking about that due to the fact that they work perfectly well with many of machining abrasives. An angle grinder with the right disc can substitute myriad tools and make the most tedious, tough jobs faster and easier.
More preferably, they are easy to control and any beginner with the correct safety precautions can pick up an angle grinder to work real fast.
● Grinding and Sharpening
Just install a grinding wheel, and you are ready to clean up and grind the welded joints, remove redundant material and do de-burring and chamfer. You’ll also be capable of restoring any edge and sharpen any plane surface with ease. If you have some rough-and-rugged tools that have lost their edge placing around, you can get them up and running using an angle grinder.
● Cutting Metal
With the right attachment, say a cutting wheel; for instance, an angle grinder can join your power tool arsenal as a metal-cutting machine.
Get a thin abrasive cutting wheel and you can cut sheet metal with this tool. Architects often use angle grinders and metal-cutting chop saws to cut re-bars that are used for reinforcing concrete.
● Cutting Masonry
Not only can use your angle grinder to cut tile, but it’s also available for masonry cutting. All you need is to install a diamond-cutting wheel, and no brick will ever come in your way. Needless to say, cutting such materials in repetition can wear off your motor rapidly, so make sure to get a powerful unit before you start.
