    • Powerful and quiet
I've been on a journey of transitioning my trusty pneumatic tools to electric, and each addition to the electric arsenal brings me one step closer to a quieter, more efficient, and hose-free workspace. This Dewalt grinder, in particular, is a shining star in that lineup. It's like the rockstar of power tools, boasting not only raw power but also the versatility to handle whatever I throw at it with finesse. From the toughest steel to the most delicate aluminum, and even the less demanding plastics, this grinder takes it all in stride, like a pro. Gone are the days of wrestling with unruly air hoses; with this electric wonder in hand, I feel like I'm wielding a lightning bolt of productivity. It's a game-changer that aligns perfectly with the modern workshop, where efficiency meets power, and the silence of electric tools allows for more focus and precision. If you're on the path to a quieter, more convenient, and still powerful tool collection, this Dewalt grinder is a must-have addition that will leave you wondering why you didn't make the switch sooner. ... show more

Works as it should, Dewalt delivers a great product. Only suggestion is when sent in mail, I wish it came in a different box. Husband beat me home and seen his Christmas gift. Grrrrr

    • So So Close
Almost perfect. It lost one whole star due to the fact that the trigger lock, which must be pushed out of the way and held there while using the trigger, is seriously annoying. The tool is the real deal, very powerful. However that trigger release is not ergonomically designed. Very very frustrating. Could have been the best cordless die grinder on the market but some clown had to ruin it with some ridiculous trigger lock. ... show more
