An angle grinder is an extremely versatile power tool that can be used for a variety of cutting, grinding and polishing jobs. This is why angle grinders are so commonly seen on construction sites and in auto garages and workshops.
Angle Grinder Usage
Angle grinders work by using rapidly rotating headgear to which you can affix a variety of interchangeable abrasive discs or blades. The fast rotation allows these super powerful tools to cut through the most resistant materials, including metal, concrete, and stone. However smaller angle grinders can also be used for more delicate work such as cutting ceramic tiles or polishing metal.
As well as cutting tough materials, an angle grinder can also be used to grind away burrs left after cutting metal with various other power saws. Using an angle grinder for cleaning rust and dirt from metal as well as polishing it is also very common. These versatile tools can even be used to remove paint and sharpen other tools and equipment.
Most angle grinders can also be used with a large range of accessories – e.g. abrasive discs for sanding, grinding and polishing, diamond-bladed cutting discs for tile cutting, to wire brushes for cleaning.
Angle grinders are fast and powerful tools. As with many power tools, it is important to take great care when using them and always wear appropriate safety clothing including safety glasses.
Angle grinders come with two common disc sizes – 115 mm and 230 mm. The majority in this angle grinder review are of the smaller size since that is perfectly suitable for most home and DIY projects. However, if you are cutting large sheet material or slabs then a large angle grinder would be more appropriate. Make sure you choose the right size accessories for your tool.
The smaller 4.5-inch angle grinder (115 mm) is lighter and easier to use and is certainly the best angle grinder for beginners. Smaller angle grinders also provide a greater level of precision and access to tight spaces and are more suited to jobs such as trimming tiles, sharpening blades, and grinding and polishing intricate metalwork.
Safety Precautions When Using an Angle Grinder
Angle grinders are fast and powerful tools and should be used with the utmost caution. Always wear safety goggles or a face shield and gloves when using one. In addition, always make sure the guard is properly adjusted for the job you are undertaking.
When using new grinding wheels or discs, run the power tool for a minute or two in a protected area to make sure it is not faulty or damaged.
Always align the grinding wheel so that it spins away from sharp edges. This will prevent it from catching and throwing the work or causing the grinder to kick back.
