A bench grinder is a benchtop type of grinding machine. It may be bolted to the floor or may sit on rubber feet. These types of grinders are commonly used to hand grind various cutting tools and perform another 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. Tips to help you on selecting the right wheels: 36-grit can sharpen most gardening tools; 60-grit is better for chisels and plane irons. Eighty- or 100-grit wheels are best reserved for delicate jobs, like shaping metal model parts.
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. Some buffing machines (buffers) are built on the same concept as bench grinders except for longer housings and arbors with buffing wheels instead of grinding wheels.
