What Are Rotary Tools?

Most, if not all, experts are well aware of a rotary tool’s versatility, power, and how it works. But beginners may find it hard to start a task with one.

In simple terms, a rotary tool is a powered handheld cutting device with a motorised tip. Think of it as a more portable version of a standard power drill.

The fast-rotating motor is connected to a spindle to which you can attach a tool bit. Attachments include cutting wheels, sanding bits, or polishing tools, to name a few.

Regarded as a multipurpose tool, it is typically powered by electricity. But you can find pneumatically powered models – operated by pressurised gas.

Generally, rotary tools are ideal for honing wood, stone, metal, glass, and plastic. Their ability to work with diverse accessories contributes greatly to their flexibility.

No matter what tasks are on your to-do list, from minor repair and DIY projects to big jobs on construction sites, a rotary tool can be useful.

The design

A rotary tool features a spindle connected to the motor, which is the part that spins. The spindle is threaded to accept the collet and the collet nut.

The collet fits directly into the axis while the collet nut screws into it. Both help keep everything in place and clamp the flanges down.

On the body, you will find the speed control. It can be a slider or comes with buttons for speed adjustments. Of course, it will also feature a self explanatory power button.

Speed feature

Rotary tools come in different models and power levels. Yet, they all share the high-speed spin, achieving the optimal results.

For one, these powerful handheld devices spin at around 20,000 RPM, while some can go for up to 35,000 RPM. Considering their small size, they can reach high speeds without causing discomfort.

To distinguish the difference for each type, look for the amount of torque a model can deliver. This also means there is a rotary tool for any task, be it a light or heavy-duty one.

Types of Rotary Tools

With the right rotary cutting tool, you can complete just about any task efficiently. But knowing which one is right for you can be overwhelming.

Consider the differences between these two types of rotary tools to find which is suitable for you.

1. Cordless rotary tools

As the name suggests, this type of rotary tool is wire-free. It is more convenient to use and transport than a standard corded multi-tool.

Most models are designed with long-lasting batteries that charge quickly. This feature lets you easily get through long days on the job.

2. Corded rotary tools

A more standard rotary tool, the corded version is a high-powered grinder that can make quick work of many jobs.

It is perfect if you work in construction or deal with hard materials like metals or stone. If you also do not mind the wires getting your way.

Tip: Invest in a small rotary sanding tool along with your chosen rotary tool type. This extra device is ideal for repairs in tight places and sanding interior cabinets.

Common Rotary Tools Applications

1. Cutting

The flexible shaft and small cutting area make a rotary tool perfect for detailed cuts. This is especially true if you are working with metals or plastics.

Other than that, you may also use the tool for:

• Shaving edges or trimming plastic
• Making fine cuts in intricate metalwork projects
• Cutting holes into plasterboard
• Slicing down the side of a stuck faucet cap with a cutting wheel
• Cutting curves in tiles

2. Carving

Rotary tools make carving and engraving a lot easier. The flexible shaft gives you full control, allowing you to engrave and draw just as you would with a pen or pencil.

A fun example of this is carving pumpkins. The small grinding attachment works well for removing the first layer of the skin.

3. Sanding

A DIY piece with tight corners and complicated details can hinder a sanding tool from doing its job. For all those hard to reach places, a rotary tool is an excellent alternative.

Tip: When your rotary tool’s sanding drum gets clogged, perk up the surface with an eraser. Run the tool at low speed and press the eraser into the clogged part to rub out the chips and gunk.

4. Drilling

The included bits can be used to drill through all types of plastic and wood. If you are dealing with an intricate drilling task, attach the bit to your rotary tool and start working.

For instance, fixing your door latch. Shave off the inside of the strike plate with the tool paired with a metal-cutting carbide bit.

Remove a small amount and test the latch by closing the door. Continue removing metal until the door latch catches.

5. Grinding

The grinding attachment is ideal for sharpening up household items like kitchen knives. It can also be used on metal projects to grind away areas with small sharp edges.

Other grinding applications with a rotary tool include:

• Making a tiny benchtop grinder
• Sharpening a chain saw
• Fixing a dishwasher rack
• Replacing faulty gas grill igniters for upgrades
• Removing stripped screws

6. Polishing

The versatile cleaning and polishing attachments can also clean your power tools! Think of it as polishing your jewellery.

Prepare for Protection Before Use

Our first safety tip is to conduct your job in a well-ventilated area. This is especially vital if the materials you use produce tons of dust.

Next, high-quality protection and safety gear are also very important. Wear a face mask or face shield to avoid inhaling fine particulates spraying around.

Eye protection should be one of your top concerns when it comes to woodworking. One of the essential precautions is to wear safety glasses.

As for hand protection, wear a pair of thick gloves to save your hands from injuries and lessen slippage. Also, consider covering your ears with headphones or earplugs to protect them from a harmfully high level of noise.

Lastly, turn the tool on before letting it contact the materials. After you finish a job, turn off the device and unplug it before changing the attachment for a different job.

The Bottom Line
