Brushless motors explained: when the premium is worth paying
Every tool listing says brushless now. Here is what it changes and when you would notice.
"Brushless" has become the word on every power tool box, usually with a price premium of £20 to £60 attached. It's a real technology with real benefits. Whether they're worth the money depends on how much you use the tool.
What it is
A brushed motor uses carbon brushes to pass current to the spinning part; they wear, create friction and heat, and waste energy. A brushless motor uses electronics to switch the current instead. No brushes to wear, less heat, more of the battery's energy reaching the work.
What you get
Longer runtime per charge, typically 25 to 50 percent. More power for the same size. Longer motor life, since there's nothing to wear out. Cooler running under sustained load. Often a smaller, lighter tool.
When it matters
Tools you run hard for long periods: circular saws, grinders, SDS drills, impact wrenches. Tools you use most days. Tools where runtime is the constraint, like a leaf blower or a hedge trimmer.
When it doesn't
A drill/driver you use for twenty minutes a month to put up shelves. A jigsaw for the occasional job. Anything where the battery outlasts your patience regardless. On those, a brushed tool from a good brand is fine and the saving is real.
The rule of thumb
Weekly use or sustained load: pay for brushless. Monthly use: don't. And check the price history — the premium shrinks in sales because brushless is where the manufacturers push volume.
