Table-mounted machine often used to cut shafts prior to assembly. Used with two attachments; one commonly is a cut-off wheel and the other is a grinding or buffing wheel. Can also be set up with a belt sander attachment.
Motorized grinder used to sharpen steel or other hard metals. Attached to a bench to raise it to a working height, the wheel is mounted either on the motor shaft or a separate shaft supported on bearings and driven by a motor through a belt.
This bench-top power tool consists of a motorized shaft with one or (usually) two abrasive wheels. Useful for sharpening planes, chisels, drill bits, knives, and other cutting tools, it also buffs and polishes when the proper disc attachments are installed. Home Improvement Encyclopedia
