I sometimes wish that there was some sort of a compact grinding wheel that I could just mount to my bench to use and hide in a toolbox for storage. To my surprise, such a tool actually exists! Engineer Inc. makes two such grinders, models TG-01 and TG-02.
The smaller grinder (TG-01, below) features a 75mm x 13mm grinding wheel, and the larger one (TG-02, above) has a 100mm x 25mm wheel. Tabletop edge-clamp capacity is 24mm and 32mm, respectively.
These small hand-cranked grinders obviously won’t perform as well as powered bench grinders, but they look perfect for users like me.
I don’t own an electric bench grinder at the moment. I’m short on space, and my very modest grinding needs cannot justify the footprint a 6-inch or 8-inch grinder would take up on my bench. When I need access to a grinder, I either use one at work or trade equipment time with a buddy.
Prices are $39 and $74 plus shipping. Both grinders are made by Engineer Inc, presumably in Japan, and are sold by I Heart Engineering.
Here’s a brief demo video showing the grinder in action:
