Cordless power tools, which utilize permanent magnets for strength and reliability, are indispensable for so many industries. Not only do they make DIY tasks more efficient, but with no cords (i.e., fewer tripping hazards), they are actually safer to use in industrial settings as well. Construction is one obvious industry where we can expect to see cordless power tools, but where else? Who else relies on cordless power tools?

In general, one can expect to observe cordless power tools in manufacturing plants, helping employees streamline production and improve quality. Mechanics and auto technicians utilize these tools (e.g., impact drivers and air compressors), as well as woodworkers (e.g. sanders, routers, and planers), metal workers (e.g., angle grinders, die grinders, and drills), and electricians (e.g., wire stripping, crimping, and soldering).

How Are Magnets Used in Power Tools?

While magnets aren’t necessarily the primary operating element in power tools, they’re still vital, especially with evolving technology. Powerful tools such as drills, saws, and grinders are typically driven by electric motors (e.g. brushless motors), which often use magnets to generate the magnetic field required for operation. You might also find magnets in the generators of some power tools to generate electricity. 

 

Magnetic chucks can be used in tools like surface grinders to hold and secure workpieces during machine operations. Magnetic sensors are used in some tools to detect positioning or track the speed of moving parts, necessary input for control and feedback systems.

Magnet Shapes For Power Tool Applications

The choice of magnet shape in power tools will vary based on application and design.

 

Here are some examples: 

  • Disc magnets: Disc-shaped magnets are often used in small, handheld power tools like cordless drills and electric screwdrivers. These magnets provide a strong, focused magnetic field for efficient motor operation.
  • Ring magnets: Ring-shaped magnets can be found in tools like angle grinders and sanders. Their donut-like shape allows for compact design and efficient force distribution.
  • Block magnets: Block or rectangle magnets are used in applications where a linear, uniform magnetic field is needed. They can be found in jigsaws and circular saws, providing consistent cutting power. 
  • Custom shapes: Some power tool manufacturers use custom-shaped magnets to optimize performance and adapt to the specific tool’s requirements.
