10 Best Bench Grinders (Review) In 2021

Our Best Choice recommendation if you are on the hunt for an 8 inch Bench Grinder is Dewalt DW758. It just so happens to be a powerfully impressive unit that is suitable for both domestic as well as commercial applications. Operating at an impressive 3600 RPM, it’s fast, reliable and has plenty of staying power. Take good care of your Dewalt, and it will have pride of place in that workshop for many years to come. From a design perspective, it certainly looks the part and its rugged and robust machine. With its cast iron base this is a heavy duty bench grinder that won’t let you down, and we have to say, given the great consumer reviews it receives, that the Dewalt is suitable for a whole range of versatile grinding operations. With two wheels position 12.5 inches apart from each other too, you have plenty of flexibility with this grinder to work on projects both large and small and can expect to achieve smooth results every time. You can combine it with a portable workbench from our list.

It’s not all about having the fastest power tools in the shed as our next slow speed bench grinder demonstrates. The Rikon Professional is another 8-inch grinder but rather than operating at a variable speed, or delivering a high RPM like the Dewalt unit we just reviewed, this Rikon operates at 1750 RPM. In this case, though, that’s very much a good thing as it means it can do heavy lift (and by that what we really mean is metal grinding) jobs without the fear of the unit overheating. It still has a powerful 1/2HP motor which means that it’s more than adequate for successfully tackling shaping as well as sharpening jobs in your workshop. There are dual dust collection points as well as adjustable safety spark shields plus a flexible LED light. All that and the Rikon bench grinding machine has a solid cast iron base with rubber feet that both minimize vibrations and hold the unit more securely in place on your worktop.
