A guard that cannot spin round under load — a small detail that stops sparks arriving where your face is.
Where we come out The best power-per-euro here, with the guard detail that most makers do not bother to mention.
Sixty-four euros for 1,100 W, and one specification worth more than the extra power: a guard that cannot rotate under load.
Everyone who uses a grinder regularly has had a disc snatch. What happens next depends on where the guard is pointing — and on many machines the guard is held by a clamp band that a hard snatch can shift. A guard that locks against rotation stays where you set it, so the debris keeps going away from you rather than towards your face.
Metabo lists it as a quality feature. It is a safety feature.
Eleven hundred watts is a real step up from the 720 and 900 W machines above: it means the motor holds its speed in a long cut instead of bogging down, and a bogging grinder is one you lean on. What this machine still lacks is a brake, restart protection and kickback detection — the three that appear from €70 upwards on this page.
Power, disc diameter, guard type and part number come from the manufacturer’s published specification. Market availability was verified per market on the EAN.

Because the guard is what stands between a disintegrating disc and you. On many machines the guard is held by a clamp band that can slip if the disc snatches, and it ends up pointing the debris and sparks somewhere other than away. A guard that locks against rotation stays where you set it, which is the whole point of setting it.
In a sustained cut, yes. Power decides how far the motor slows when the disc is buried in a section — and a grinder that bogs is one you push, which loads the disc sideways. For occasional dressing the difference is invisible; for cutting 40 mm (1.57 in) box section repeatedly it shows within minutes.

Steady cutting and grinding in the workshop, where the tool stays on the bench between jobs
Here because the consumable states this machine by name.
Amazon reports what buyers took in the month before this page was last checked: at least 50.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for welding and metalworking machines and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
1,400 W · constant electronic · soft start · €100
The same 1,400 W as the Metabo beside it, with a soft start it does not have and a quick-change nut it does.
Best for: Steady, heavy grinding where the machine runs for minutes at a time
900 W · 2,800–11,000 rpm · speed preselection · €61
Variable speed at €61 — which matters because stainless, paint and thin sheet all want a slower disc than steel.
Best for: Mixed work — stainless, painted steel, thin sheet — where full speed is the wrong answer
720 W · 176 mm (6.93 in) grip · flat gear head · €46
The cheapest professional-line grinder here, bought for its 176 mm (6.93 in) grip and its flat head rather than its power.
Best for: Light dressing, deburring and short cuts, where the tool is picked up and put down all day
