What is an Angle Grinder
Angle grinders are considered to be one of the most common power tools. This statement is well-grounded as a grinder can cut through tile, stone or metal, and remove rust or old paint. Naturally, such a large scope of application makes grinders helpful in professional construction and household tasks or repairs. The review covers 5 most popular models where you can choose the one that fully meets your requirements.
What Features to Compare
Choosing an angle grinder, you should decide what you are buying it for. A household model with the power from 7А to 10А is enough for cutting small pieces, fine metal sheets, plastic as well as for polishing and grinding. If you need to handle concrete, stone or thick metalware, it's reasonable to pick an industrial-grade model from with the power from 10A to 15А (and more). The speed is another important parameter you should consider. It totally depends on a cutting wheel diameter. The bigger the wheel is installed, the smaller the speed a grinder delivers; and vice versa. The grinders fitted with small wheels run at 11,000 RPM and higher, while heavy-duty models deliver about 6,000 RPM.
Cutting Wheel Diameter
Considering the wheel diameter of an angle grinder, choose it in accordance with your cutting needs. Household models usually come with 4-1/2 - 5" wheels and can polish, remove rust and paint, cut sheet metal and tile. The 7" wheels (and larger) usually serve for cutting concrete, masonry, asphalt, thick metal, and other tough items. The grinders fitted with such wheels are able to perform long and withstand high loads. Choosing a wheel, consider the materials you're going to cut and the maximum rotating speed; these aspects should never be ignored! Pick a wheel the maximum speed of which is higher than the RPM of your grinder, otherwise, as it might shatter.
In this paragraph, we will consider safety features of a grinder for itself and its users. Firstly, almost each grinder is fitted with a lock-on button to prevent accidental starting. Secondly, some models feature spiral gears to reduce noise and deliver a better performance. Nevertheless, it's advised to use hearing protectors, no matter how noisy a grinder is. Also, some grinders come with restart protection and anti-kickback clutches for the user's safety. As for other safety features, dust protection is among the most important ones. The manufacturers protect their equipment by sealing the wires with resin or closing the bearings with washers. In addition, grinders are often protected against overload by aluminum or magnesium motor cases that cool down faster and are more durable than the plastic ones.
Convenience and Compatibility
Speaking of the convenience of an angle grinder, we would like to highlight the shock-absorbing handles that are desirable in eaсh model. As a grinder works, it inevitably vibrates, hence wearies your hands. So, these tools are often equipped with damping handles to reduce vibrations. We should also mention a wheel guard that may not be included in the package. This guard will protect you from grindings and sparks and deliver a clear view of the material you cut. A quick-release clamp of a guard will let you install it in a convenient position and resume working.
