Best Rotary Tools of 2022

1. Why invest in a rotary tool?

A rotary tool is a versatile instrument to have in your workshop garage. This tool performs a wide range of operations but it’s adaptability to a specific demand is dictated by the number of accessories it comes with. In broad lines, a rotary tool can be used for:

• Cutting
• Scraping
• Engraving
• Etching
• Sanding
• Grinding
• Sharpening

2. Types of rotary tools

We can distinguish between two kinds of rotary tools, the basic models, and the cut-out rotary tools.

• The basic rotary tools are ultra-compact and very easy to handle. They are ideal for hobbyists and beginners, but also for those professionals who don’t use such a tool frequently. These instruments are usually powered by small motors of up to 1.8-Amp and are perfect for etching and engraving, cutting, and sanding restricted surfaces. Slower than the cut-out tools, these basic models are easier to control and more flexible to use.
• At the other end of the spectrum, there are the cut-out rotary tools equipped with larger motors of up to 5-Amp. Cumbersome and heavy, these tools are typically used for commercial or industrial applications, usually to cut through hardwood and metals. Despite coming with a wider range of attachments, the cut-out rotary tools are rarely considered by home users.

3. Corded vs. cordless tools

Like most workshop equipment, the rotary tools come in corded and cordless variants. There are endless debates on which is better, as they both have their own pros and cons.

• Corded rotary tools: Are the most popular due to their limitless power. They are also more powerful than their cordless counterparts and capable of spinning the attachments at higher rates. This ensures suitability for a broader range of projects, but the unit’s mobility is conditioned by the length of the power cord and position of the socket.
• Cordless rotary tools: Come with some advantages as far as mobility is concerned. They can be used anywhere, no strings attached. This is one of the main reasons why more and more DIYers turn from corded to cordless. On a downside, the cordless rotary tool is heavier than the corded one due to the battery. You’ll also have to settle for a limited runtime and weaker capabilities.

4. Power & Speed

Amateur rotary tools are powered either by motors that vary from 1.2 to 2-Amps or by batteries between 4.8 and 18 volts. The mid-range and higher end units have typical speeds between 5,000 and 35,000 RPM, with the cordless models spinning slightly slower than the corded units.

The best rotary tools come with variable speed settings that usually cover the whole range mentioned above. These tools are incredibly versatile as they allow you to adapt the speed to the task, such as:

• Polishing, etching, and craving – 5,000 to 15,000 RPM;
• Cleaning rust or sanding surfaces, shaping acrylic nails – 15,000 to 20,000 RPM;
• Removing old paint, cutting – 20,000 to 30,000 RPM;
• Drilling holes – 30,000 to highest speed setting.

Some low-end models may have a single speed, but it’s quite rare to come across such a tool.

5. What accessories would you need?

If you need a rotary tool for one determined task, perhaps the accessories the instrument comes with are the least of your worries. But since this apparatus is so versatile, it would be a pity investing in a tool that comes with few or no attachments.

Here are some of the essential attachments to look for:

• Cutting bits: Allow you to cut holes and shapes through wood, plastic, and soft metals.
• Cutting guide: A useful accessory that guides your cutting line. It comes in handy when you have to respect a predetermined pattern or intricate shapes, but also when you have to cut in a straight line.
• Engraving tip: Perhaps the most praised by crafters. It allows you to engrave or etch wood and other materials.
• Grinding wheel: As its name suggests, it is used for grinding of the surfaces, such as stone, wood, glass, ceramic, and more.
• Sanding drums: Useful if you want to smooth a surface before passing on to the next step of your project.
• Brushes: Typically used for polishing metals and other materials.

Some rotary tools include a more extensive range of attachments like drill bits and diamond points, while the best rotary tool must also come with a convenient carrying case.

6. Other features to look for on a rotary tool

• Weight is an important thing to consider. Some projects, such as engraving wood or polishing jewelry can require you to hold the tool for an extended period of time, and a heavy instrument can easily become unmanageable. As a rule of thumb, remember that cordless models are heavier.
• The grip is as important as the heft. Even the most lightweight tool won’t do you good if it requires you to hold it in an odd position. Invest in an ergonomic rotary tool that comes with a 360° anti-skid grip.
• Another critical aspect is the ease of use, especially if you have to change between accessories frequently. Some models use chucks that allow switching from an attachment to another without the need for a wrench.
• If you decided to invest in a cordless model, you should also consider the battery. Li-Ion is the most performing as it lasts longer than NiCad. Some rotary tools come with interchangeable batteries that work with all compatible tools, and that can be replaced by a charged one when fully drained.
• On a corded model, it is important to check the length of the cable. If you have to move a lot around the workbench, choose a model with a longer cable to avoid plugging the apparatus into an extension cord. On the contrary, choose a shorter cord if you want to use the tool in a fixed position next to a wall outlet.
• A carrying case is not essential, but it’s nice to have as it provides you the perfect storage space for the tool and its accessories.
