the Metabo DS 200 bench grinder is our top choice for many good reasons. For a start, it is a heavy duty machine that can easily tackle any work you throw at it. This 8 inch bench grinder weighs in at about 35.9 pounds, so it isn’t light by any stretch of the imagination, however due to its compact size it is still relatively portable. One good thing about the grinder weighing more, is that the heavier models tend to be better at reducing unwanted vibrations. That being said, it’s still best to mount this machine to the floor with bolts, for safety if nothing else. The electrically powered motor has an impressive 240 V, 600 Watts capability, powering the wheel up to 3,570 RPM. Because of the fact that it spins very quickly, and is quite a heavy weight, some note that it does take a while to slow down upon switching it off.

It may be overkill for the beginners out there, but for most, this bench grinder is certainly worth considering.

Consider before buying a new bench grinder
Power & Speed
When considering which product to go for, think about whether your use of the machine will be on light tasks or heavy tasks requiring a bigger more powerful/faster motor. Bench grinders typically have an RPM range from 2000 RPM to 4000 and up. It varies from model to model, but the best advise is to choose one with adjustable speed settings so whatever you’re doing you can simply change the speed to suit your needs.
Grinding Wheel type
The type of grinding wheel that comes installed on the machine is important (however it can be changed out later). The different wheels are for different jobs and materials. Some materials will call for a more coarse wheel and some others will need it to be less coarse for a finer result. Some models even come with medium and coarse wheels so you can swap them yourself depending on what the task at hand calls for.
Sturdy & Reliable
A good machine should have reviews from consumers that reflect its quality and reliability. It’s important that it has a solid build quality so it can stand up to being used often without breaking down. It’s also a good idea to look for one that features a cast iron base as this prevents wobbling while grinding.
Built in light
Even if your work space is well-lit, it’s a bonus if you can find a machine that comes with an LED light built in. This helps to illuminate the area you’re working in specifically, helping with more precise and effective work, it’s also a safety feature.
