Best Bench Grinder Buying Guide
Strength of the motor
One factor you should never forget to consider is the motor speed and revolutions per minute it can produce. Different models have different grinders and you should look out for one that can produce an rpm of at least 3500
Type of guard that it has
The job of a guard is to shield the grinders on the tool and it protects the hands of the user from the spinning wheel. A guard should also be easily removable or adjustable when you need to create space for your work.
Features that reduce vibration
It’s good to consider how much vibrations that’ll be gotten when using your bench grinder. The anti-vibration features that are deployed in a bench grinder are the features that’ll help reduce the vibrations to a possible minimum. It could be either a cast-iron feet, rubberized base or even wheels.
Spark shield
Quite a number of bench grinders these days have features that help protects users of the bench grinder against sparks and debris coming from the grinding wheels. Some manufacturers include safety goggles in the package while other units come with guards that keep the sparks away from your face and closer to the grinder. See more safety precautions here when using a bench grinder.

You should make sure you’re aware of the cover the warranty offers. You might get a bench grinder whose warranty covers both the motor and grinders while another warranty might cover just the motor. Whatever it is, the warranty should last for at least a year.
