Any of you that are familiar with grinders have probably noticed that many of the best features that I’ve talked about are usually only available from Metabo. I’ve used and burned up almost every brand of grinder on the market, and while they’ve all made huge improvements over the years, they’re still behind in terms of features, power, comfort, and durability. Metabo is literally the Cadillac of grinders.
So for my top of the line, money is no object, best 6″ grinder i’d choose the Metabo WE14-150 Quick
This is a 6″ – 150mm, 1400 watt-12 amp grinder with all the bells and whistles. It’s got electronic soft start, the tool-free quick wheel change System, safety clutch, overload protection, and a very nice feature called no volt release. What this means is that if you lose power while the grinder is switched on, the grinder won’t start back up when the power is turned back on. If you’ve ever worked on a construction site and are familiar with how often power goes out, you’ll understand how important this is. Another great feature of this grinder is the guard. You can easily move the guard by hand. No special tools are needed, and the design is well thought out and reliable.
For a 5″ it’d be the Metabo WE14-125VS.
This is basically the same except that it also has a variable speed feature that provides adjustment from 3,000-10,500 RPM.
I really can’t say enough about these grinders. They’re smooth, they’ve got tons of power, and they’re comfortable to use. You can work them hard all day long, day in and day out, and you won’t have to worry about burning them up. I’ve used them for years and until something better comes along, i’ll use them for years to come.
In 2nd place the Bosch 1806E.
It’s a 6 inch – 150 mm, 1400 watt – 12 Amp model with soft start and overload protection. It’s also got kickback protection and no voltage restart protection.
And for a 5″ Bosch grinder, the Bosch 1803EVS.

It’s a 1000 watt – 8.5 amp, 5 inch – 125mm grinder. Even though it’s only a 5 inch grinder, it comes with lots of great features. It’s got soft start and variable speed, and an easily adjustable guard. One thing I like about Bosch grinders is that they’re very powerful and solidly built. They feel substantial, not cheap like some of the other grinders. Bosch is Metabo’s closest competition, and if they keep improving like they’ve been they’ll soon be neck and neck.
And in a somewhat distant 3rd – the Makita 9566CV
This is a 12 amp – 1400 watt, 6 inch – 150 mm grinder. It’s got a 5 stage variable speed adjustment, and overload protection. Makita now has what they call SJS – Super Joint System. This is their version of the slip clutch.
For a 5″ grinder, you can choose the Makita 9565CV
As far as the specs are concerned, it’s identical to the 9566CV except that it’s limited to a 5 inch wheel.
And finally, the best deal of the day The Northern Tool $12.99 grinder.
If you’d like a disposable grinder or two to use with a wire wheel, or something that doesn’t require much power and only gets occasional use, this one from Northern Tool should be perfect. I’ve used a few of them and they’re not bad for a 13 dollar grinder! And even when you do burn them up, you’ve probably already got your 13 dollars worth.
So there you have it, my personal favorites. I know there are many people out there that prefer some of the other brands like Milwaukee or DeWalt, but in my opinion these grinders just aren’t in the same league as Metabo or Bosch. They’ll do the job, but they’re either lacking in features, underpowered, uncomfortable, or unreliable.
