Description of Durable DEWALT DCG405B ⚙️ Grinder with Enhanced Kickback Switch
Brushless motor of the angle grinder requires no brush changes. DEWALT grinder's brake stops wheel in 2 seconds or less on average. Kickback Brake engages when a pinch, stall, or bind-up event is sensed and the electronic brake engages with maximum force to quickly stop the wheel, reduce the movement of the metal grinder and shut the grinder off. Power Loss Reset prevents accidental restarts following a power disruption when the tool is left in the "on" position.
This product was purchased to grind approximately 1/8 inch of several very small areas of concrete floor (16 square feet total). It only works for about 10 minutes on a 5Ah battery. Each battery takes about 30 minutes to cool sufficiently to even begin charging, plus an additional 2 hours to fully charge, giving a total of +/- 2.5 hours to charge a single battery. I get about 25 minutes with two 5Ah batteries and one 3Ah battery before taking a few hours off. I am convinced that this product is
Pros
Brushless angle grinder motor requires no brush changes.
When I bought this one I bought different types of wheels but the first time I used it I was in the garden for a customer on a Sunday. I needed to cut regular size pavers but everything was closed so I used a diamond blade and got to work with this angle grinder. Now I only have 1.5Ah batteries and they drained pretty quickly but I only had to make 3 cuts and everything was great. The safety cutoff works great for those of you who prefer the paddle switch when too much force is being applied to
Pros
Power Loss Reset prevents an accidental restart after a power failure while the device remains powered on.
Got this to add to my 20v tool kit My kit had a more typical trigger switch but I don't particularly like this feature for longer grinds -Sessions (just my preference). This coffee grinder is powerful, light and has excellent ergonomics. The motor is powerful and efficient, and has spent a relatively long time grinding, cutting rebar and grinding weld beads (so people don't see what a crappy welder I am!). And it has good braking which came in handy when one of the handlebars pinched the wheel…
Pros
DEWALT grinder brake stops a wheel in an average of 2 seconds or less
