    A professional grade cordless angle grinder
  

*by D***. on Reviewed in the United States on March 18, 2024*

I have several Flex tools and they have proven to be professional grade tools that have yet to disappoint.  This cordless grinder continues that legacy.The first thing you’ll notice is the size and weight, this isn’t a cheap throw-away tool.  At over 3 pounds, the grinder is fairly heavy compared to the consumer grade angle grinders.  It is also a bit longer.  It comes with a 5Ah, 24-volt battery, which, as you’d expect, is fairly large and weighs over 2 lbs.  When fully assembled you end up with a grinder that (without a grinding wheel attached) is about 15 inches long and weighs just over 6 pounds.The grinder offers multiple speeds, however the speed is not variable via the paddle switch.  The speed is adjusted via push buttons on the handle which offers 4 options, selectable via the plus and minus buttons.  Having adjustable speeds is a requirement for my work, so I am happy this grinder offers it.  The slower speeds work well for non-abrasive finishing discs and the higher speeds are good for cutting and grinding.Everything about this grinder is well thought out.  The electronics are protected by fine metal screens integrated in to the vents in the handle, the safety guard is extremely easy to reposition via a simple latch mechanism.  The handle is robust with good vibration padding, and the length and balance of the tool works well with the paddle switch to provide a solid grip and excellent control.The 5Ah battery has large charge indicator LEDs on both sides, which is a nice touch that makes keeping track of the remaining charge easy.  Speaking of battery, the fast-charger is solid and robust.  It has a built-in fan to keep things cool while charging, which is a great feature that extends the life of the battery and the charger.The unit I ordered came as a kit with the grinder, battery, charger and a zippered carrying bag.  As I mentioned, as with all my Flex tools, this is a pleasure to use and is built for the professional.  I have no doubt it will survive my metal fabrication shop and will make on-site work a lot easier.

    Quality item
  

*by A***R on Reviewed in the United States on April 4, 2024*

This is a very well made angle grinder with plenty of power/torque. It feels substantial/robust and yet fits well in hand and is nicely balanced with the 5Ah battery. The battery charges very quickly and lasts around 35-45 minutes. There did seem to be a slight lag getting up to full RPM compared to other cordless grinders I've used (but not a significant lag). I haven't needed to use this on a lower speed but it's good to have the variable speed option available.
