The best bench grinder should have a motor with a minimum rating of 150W so its grinding wheels won’t be slowed down when you’re grinding or polishing. Look for wheels that spin at a rate of least 2,500rpm.
To minimize vibration and noise a bench grinder should weigh at least 6-7 kgs and come with rubber feet and bolt holes for firm mounting to a workbench.
Spark guards and tool rests are important features too.
There is a wealth of accessories available for use with a bench grinder so you should ensure that the grinding wheels can easily be swapped out for appropriate attachments, such as polishers, mops and wire wheels. There are many kinds of grinding wheel too, with different diameters and widths and available along with coarse and fine grit options. The most common diameter wheels are 200mm and 150mm, whilst widths can vary from 16mm to 40mm. Bench grinders that come with wheels of different width are often a good option.
Such a range of options is ideal for fettlers, restorers, and hobbyists. I’ve heavily researched the best ones available right now, all so you don’t have to. Read on to see what I’ve discovered…
