Angle Grinder: Its All In The Wheel
A big part of what makes angle grinders so versatile is the fact that they use different “wheels.” These wheels have different functions and by having access to a wide variety of different wheels at your disposal you are ensuring that your angle grinder can tackle any job that you need it to.
So, when shopping, remember that you don’t just want the best angle grinder available, but also the best wheels.
While going through every kind of wheel would be impractical, we are going to introduce you to some of the more common, important wheels.
First up you have your standard abrasive wheel. This wheel is used for regular grinding jobs. If you need to grind down metal surfaces, then a standard abrasive wheel is all that you need. There is some variation within this category, for example, abrasive wheels come in different grit levels which impact their performance.
Diamond wheels are your powerhouses. These wheels are capable of cutting through tough surfaces like metal, concrete, tile, brick, and just about anything else you put in front of it.
Sanding wheels, as you might have guessed are good for sanding down wood with precision and power. If you are into woodworking at all, then this is definitely a good wheel to have available.
Finally, there are wire wheels. Now, as we mentioned earlier, angle grinders can be used to clean metal and to scrape away rust. In order to do that, you need a good wire wheel.
When looking for the best angle grinder, you want to make sure that you place a high priority on finding one with a powerful motor. Now, with pretty much every power tool out there you want a powerful motor, but it is even more important when it comes to angle grinders.
This because angle grinders are expected to tackle some very tough jobs (such as cutting through metal or concrete) and so it is important that the angle grinder has a motor that won’t give out.
Measuring the strength of a motor on an angle grinder can be done by looking at two things, the amps and the RPM (revolutions per minute). The best angle grinder is one that has a high amp rating (7 or above) and that has a good RPM (10,000 or above).
Whether To Go Cordless Or Not
Like many other power tools, angle grinders come in corded and cordless varieties. And like many other power tools, each type has its own advantages and disadvantages. However, we think that corded angle grinders and generally the better option for both professionals and amateurs alike.
While cordless grinders may be the more mobile option, you just can’t match the sheer power that corded grinders are able to put out. As was discussed earlier, power is very important when it comes to angle grinders, so going with a more powerful corded option is the best option.
Now that you know about all the jobs that an angle grinder can do, about the different wheel types, and how to evaluate an angle grinder, you are well-prepared to pick out a really good grinder when you go shopping.
