Craftsman 21162 Professional Variable Speed 8'' Bench Grinder
This is an upgrade from the six-inch grinder that I had on this list last year and at that time, I didn't know they made an eight-inch version of it. I’ve used Craftsman tools for years, although I don’t often rate them the highest on these lists because while Craftsman makes great tools for the homeowner, there are professional grade tools out there which are better. Not in this case.
Dollar for dollar, I believe this is the best grinder on the market. The most impressive feature on this grinder are the tool rests, which are sturdy and come with an attachment for holding drill bits at the right angle for sharpening. There’s an integral water cooling tray which is necessary when sharpening tools so they don’t overheat and lose their temper. It’s also variable speed with a control from 2,000 to 3,450 RPM. It even comes with a wheel dressing tool and oversize spark guards. Oh, and don’t forget the integral work light, so that you can see what you’re doing.
