For this post, I have put together a collection of the best bench grinders currently available.

A bench grinder is a benchtop type of grinding machine used to drive abrasive wheels. These types of grinders are commonly used to hand grind various cutting tools and perform other rough grinding.

Depending on the bond and grade of the grinding wheel, it may be used for sharpening cutting tools such as tool bits, drill bits, chisels, and gouges. Alternatively, it may be used to roughly shape metal prior to welding or fitting. A wire brush wheel or buffing wheels can be interchanged with the grinding wheels in order to clean or polish workpieces. Stiff buffing wheels can also be used when deburring is the task at hand.

The typical wheels on most bench grinders are vitreous-bond wheels. They work best to do their intended task, but they inherently have a risk of cracking. Grinding wheels designed for steel are not to be used for grinding softer metals, like aluminium. The soft metal gets lodged in the pores of the wheel and later expands with the heat of grinding. This can dislodge pieces of the grinding wheel, causing injury.

Wheels come with maximum RPM ratings printed on the label. The grinder's RPM must be equal or lower; "the maximum operating speeds indicated on the wheel's tag must never be exceeded". Greatly over-speeding a grinding wheel could cause it to explode.

The following bench grinders use the latest innovative components to meet your needs and help to ensure you do your best work.

So here is my list of The 10 Best Bench Grinders.
