Design and
Functioning of an Oscillating Tool
Description of its design
An oscillating tool, often recognized by its compact and lightweight
stature, is ingeniously designed for versatile functionality.
Essentially, the tool resembles an enlarged electric toothbrush with the
motor housed within the main body. From a side profile, it has an
elongated shape, with the handle often being rubber-coated for a better
and comfortable grip.
Many designs incorporate a power switch on the handle for easy
accessibility. On one end, it sports a head that’s designed to hold
various attachments, enabling the tool’s multi-functionality. The head
oscillates back and forth at high speed, enabling swift and precise
work.
The attachments or accessories are attached to the head either by a
quick-release lever system or a bolt and washer system. The former
allows for hassle-free accessory changes while the latter offers a
higher level of security, ensuring that the attached tool doesn’t loosen
with vibration.
What sets an oscillating tool apart from other tools is its minimal
movement. The power from the motor causes the head to move in a rapid
see-saw motion or oscillation at a very limited angle, hence the name.
This sophisticated design allows for precision and control, making the
oscillating tool a popular choice among do-it-yourself enthusiasts and
professionals alike.
Explanation of how it works
An oscillating tool, also known as a multi-tool, works by delivering
rapid oscillations at a minimum angle to the attached tool bit. The
motor inside the tool drives these oscillations, which can range from
3,000 to over 20,000 oscillations per minute (OPM), depending on the
power and speed settings selected.
The remarkably small oscillation angle of about 1.4 to 3.2 degrees
distinguishes the tool’s operational mechanism. This tiny angle allows
for a cutting, sanding, or scraping motion that is safe yet highly
efficient. Essentially, the high-speed oscillations create a vibration
effect that allows the tool to perform various tasks, depending on the
attachment fitted into the tool head. It’s this rapid side-to-side
motion that enables the oscillating tool to do its work without the
kickback or high level of guidance required for other power tools.
What’s more, thanks to the oscillating movement, the tool only works
when it’s pushed against a surface. This feature ensures a high level of
control for the user and minimizes wastage of energy. In effect, an
oscillating tool offers a unique combination of controlled power and
finesse that is difficult to find in other power tools.
Types of Oscillating Tools
Corded Oscillating Tools
Corded oscillating tools are one of the classic versions of this
versatile device. Their primary power source is electricity, and they
connect directly to an outlet using a power cord. This type of tool
offers a constant high power level as they don’t rely on a battery that
may gradually lose charge over time. Ideal for stationary or extensive
work projects, the corded oscillating tool can operate continuously
without the user worrying about battery life. Unfortunately, the cord
can pose a bit of a limitation to the tool’s mobility, potentially
hindering movement or access in tight or hard-to-reach areas.
Additionally, care needs to be taken to avoid cord damage or pulling the
plug out of the outlet during usage.
Cordless Oscillating Tools
Cordless oscillating tools, as the name implies, operate without a
power cord, running instead on rechargeable batteries. This offers a
significant level of convenience and mobility to the user. Because they
are not tethered to a power outlet, they can easily be used in spaces
where electricity is difficult to access, like a distant corner of a
yard or a high point on a structure.
Typically, these tools use lithium-ion batteries, which are
lightweight and have an appreciable energy capacity, providing adequate
power for most tasks. The batteries come in various voltages, typically
ranging from 12V to 20V, and their lifespan will vary depending on the

same raw power as corded ones, particularly for extremely demanding
jobs. However, for many homeowners and even professionals, the
convenience, mobility, and sufficient power of cordless oscillating
tools make them an attractive choice.
Pneumatic Oscillating Tools
Pneumatic oscillating tools, also known as air-powered oscillating
tools, are another category in the grand family of oscillating tools.
They are primarily used in industrial and heavy-duty applications due to
their formidable power and performance. These tools rely on a steady
supply of compressed air to function, which is typically delivered via
an air compressor.
Their operation doesn’t involve any electrical components, which
makes pneumatic oscillating tools ideal for use in environments where
electricity may pose a risk, such as wet or flammable spaces. This is
more than a mere safety convenience; it’s a life-saving measure.
Being powerful, durable and reliable, pneumatic oscillating tools are
often the go-to option for many professionals. Despite their numerous
advantages, these tools are not extensively used in domestic settings.
This can be attributed to their need for an external air compressor,
which elevates the total cost of owning and operating pneumatic
oscillating tools. Furthermore, they tend to be bulkier and noisier than
their electric counterparts, which could also hinder their use in
quieter, residential areas.
Nevertheless, for those seeking a sturdy and efficacious option for
demanding tasks, a pneumatic oscillating tool could be an invaluable
asset in your toolkit.
