Angle grinders are versatile tools that can be used in a variety of tasks including cutting metal surfaces, removing loose paint from walls, shaping small tiles and sharpening mower blades just to mention a few. These devices come fitted with a pair of detachable grinding wheels that also make them easy to use for a variety of tasks around the home.
Nevertheless, before starting any work it’s always important to know what you’ll be using the equipment for so as to prepare well in advance. This way you’ll also be able to choose the most appropriate type of grinder for the job. When used correctly, this machine can help you finish multiple tasks in record time.
Where to buy
The angle grinder can be found in most hardware stores where power tools are being sold. There are large versions available but the most popular ones are 4 and 4.5 inch grinders, they are perfectly sized for most tasks. Though you can buy costly high-end models, for frequent demanding home tasks such as cutting cement or stucco look for those with powerful motors of between 5 to 9 amps.
A machine’s ability to accommodate different accessories and wheels is also important, versatile equipment should preferably include items such as spindle nut and spindle washer for better functionality. These can be installed in varying configuration settings to accommodate thinner or thicker wheels, depending on what the device is running on. Even so, before screwing in wire wheels or cups onto the grinder’s threaded spindle, first consult with your instructions manual for more information on how to go about this task.
When shopping for them at the hardware store you may find that abrasive wheels look quite similar, but don’t be confused as they are designed to perform different roles.
How to use it
I. Choose a machine that’s best suited for the project at hand. Generally, electric models pack more power and are best suited for large-scale jobs that cover immense surface areas. On the other hand, pneumatic grinders are much less powerful, but still easier to operate and suitable for lighter jobs in tight fitting spaces.
II. Pick appropriate discs. Polishing pads and sanding discs are typically used for finishing tasks, while cutting discs will be more useful in masonry, cutting tile, removing rust/paint and resizing steel or pipes.
III. Secure your work material firmly onto a stable surface and ensure the guard is well fitted. Note that grinding discs can also be used for milling stone and metal, but in whatever you do never try using a slicing disc for performing grinding work.
IV. Hold the machine down with a strong grip preferably against the weight of your body, rather than handling it from the edge. Next, move your grinder towards the handle’s direction to prevent it from kicking back or the disc slipping from its position. This may ruin your job and even cause injury so be careful.
V. Finally, when grinding work is complete lift off the shredder from the surface slowly and store in a safe dry place away from direct sunlight.
When pulverizing metal always apply light pressure to prevent overheating the material. Additionally, keep a small bucket of water and rag nearby to occasionally moist the metal so that it can remain cool as you continue grinding. Remember to always unplug the grinder when changing wheels so as to avoid kickback, similarly sometimes milling can cause sparks so try working at a safe distance away from inflammable materials.
Use the machine guard whenever possible as this will prevent minor injuries. Furthermore, never wear loose apparels or headphones which can easily get caught inside the angle grinder. All in all exercise proper safety precautions and leave nothing to chance. The most common injuries that affect people using this device are on the head and face, therefore wear appropriate face shield or safety goggles and heavy-duty work gloves. Other things you may need are earmuffs and sealed respirator facial mask, this will protect one from inhaling dust particles or metal shaving that may be produced as residue from the worksite. In general, angle grinders are commonly used in construction and metalwork tasks as well as emergency rescue operations. They are usually found in workshops, auto-body repair shops and even service garages.
