Makita GA5091X01 vs FLEX 2000 W 125 mm, with brake

At the top of the grinder market, which safety specification is measurable?

Both machines have the three features that matter. Only one of them puts a number on its brake, and that is the difference between a claim and a measurement.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these machines answer different questions.

Which of the two, for which metal

Buy the GA5091X01

Buy the Makita for the complete set at the lower price: brake, anti-restart, jam detection and variable speed, on all six markets.

2000 W 125 mm, with brake

No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.

Buy the FLEX if you want the brake time in writing. Three and a half seconds is a measurable claim, and a brushless motor is the durability argument for a tool used daily.

The questions welders ask

Does a published brake time really matter?

It is the only way to compare. « With brake » appears on many machines and describes anything from three seconds to a token drag. The window between releasing the switch and setting the tool down is where accidents happen, and 3.5 seconds is a figure you can hold a manufacturer to.

Is 2,000 W too much for a first grinder?

Yes. Both of these are professional tools, and a jam at that power is genuinely dangerous — which is exactly why both have jam detection. For occasional work the €46 to €100 machines on the grinder page are the sensible range.
