Rotary Tool Review GuideEver since the Industrial Revolution changed the way that products and items were manufactured, tool designers have been coming up with new ways to streamline and perfect production. Tools such as corded power drills, angle grinders, and rotary tools have made construction exponentially simpler. Rotary tools were originally designed for use by experts machinists, who would carefully guide the powerful drill or burr to machine extremely precise dies and molds. Old-timers and industry insiders still refer to these tools as “die grinders” for this reason, but most people today call modern models “rotary tools”.

Homeowners, property managers, woodworkers, contractors, builders and hobbyists can use a rotary tool to perform a wide range of tasks, including sanding, honing, sharpening, polishing, grinding, and machining metal, wood, and other hard surfaces. Today’s advanced rotary tools use powerful motors to create a strong circular rotation to drive attachments and accessories such as burrs, bits and grinders. High speed rotation and substantial torque drives rotary tool attachments to quickly and efficiently achieve precise control when grinding, sanding or polishing wood, metal and other items.

What is a Rotary Tool?

Originally, industrial “die grinders” or rotary tools used compressed air to rapidly drive the circular motion of the tool, but today’s models feature advanced electric motors to achieve greater torque and more revolutions per minute. The primary function of the rotary tool is to create a powerful circular rotation that can drive attachments and accessories such as burrs, bits, saws and grinders.

Considered by many people to be a “Dremel”, the brand name of a popular line of rotary tools, quality rotary tools of different dimensions and abilities are available from multiple manufacturers. With an enormous variety of attachments that can be powered by a rotary tool, home builders, crafters and hobbyists can easily perform woodworking, engraving, shaping, polishing, machining and grinding tasks. The collar or area of the rotary tool that connects to attachments is known as the “collet”, with different sizes and designs used for different attachments.

What are the different types of Rotary Tools?

Modern rotary tools are designed for a wide variety of home woodworking, engraving, grinding, sanding and other repair and building tasks. While almost all modern rotary tools are powered with electric motors, some use direct, corded power to operate while others are equipped with a battery pack to be used independently. Rotary tools come with a variety of options, including speed control to allow for precision work, and torque for heavier grinding or polishing jobs.

Some rotary tools today come with universal collets that can be used with nearly any second-party rotary attachment, while other rotary tools feature popular collet sizes commonly used in the power tool industry. Some rotary tools also include a number of attachments to offer buyers a complete package for their rotary tool needs.

What are the advantages of owning a Rotary Tool?

An enormous number of quick jobs around the house can be efficiently and rapidly accomplished with the use of a rotary tool, including polishing, sanding and engraving. Whether recording serial numbers on expensive electronic items or using honing attachments to sharpen knives and blades, a rotary tool can offer quick and powerful solutions to a wide range of home repair, maintenance and building tasks. Some home builders use rotary tools to quickly cut through drywall, plasterboard, and other thin sheeting materials.

Woodworkers can use rotary tools to shape and sand angles, curves and other delicate features. Many businesses charge steep prices for simple engraving or honing jobs, so having your own rotary tool at home can save you a substantial amount of money and lost time. With thousands of attachments available, a rotary tool can easily become one of the most versatile and useful tools any homeowner, hobbyist or property manager can own.
