One of the most versatile tools in today's workshop is the high-speed rotary tool. Both corded (figure A) and cordless (figure B) models, with variable speeds and a wide variety of bits, are available (figure C).
Some of the different types of bits include the cut-off bit (figure D), which works well for cutting off nails or screws, and the engraving bit (figure E), which is useful for marking property.
A variation on the rotary tool is the spiral-cut saw (figure F), a more powerful tool designed to cut through wood, dry wall, metal and tile.
The router is a large version of the rotary tool and spiral-cut saw. It uses special bits (figure G) to shape the edges of wood. A knob on the side of the router controls the depth at which it cuts the wood (figure H).
Different types of routers are available. The plunge router (figure I), which raises and lowers the bit as it cuts, works well for mortising. The trim router (figure J) is a small router used for trimming countertops and creating woodcut signs.
