Brushless or brushed — where the money actually goes

A brushed motor loses energy as friction and heat at the commutator. A brushless motor switches electronically instead, so more of the battery reaches the chuck. That is the whole mechanism, and it explains every real difference between the two.

Where the premium pays back

• Runtime. Expect roughly a third more work per charge on the same battery. On a fixing-heavy day that is one fewer battery to own.
• Service life. No brushes means no brush changes and no dust ingress at the commutator, which is what usually ends a site drill.
• Sustained load. Brushless holds torque better in long cuts and large-diameter holes, where a brushed motor fades as it heats.

Where it does not

On intermittent work — a few dozen screws a week, occasional pilot holes — a good brushed tool will outlive its owner s interest in it. The premium buys capability you never draw on.

Our rule on the counter: brushless for anything used daily or run under sustained load, brushed for second tools and van spares.
