This is easily 8 times faster than my standard 20V Dewalt hammer drill (using the same battery and bit!). First time I used it, I thought I drilled through a wooden wall (it was masonry), then a few minutes later I drilled through a solid concrete hotel floor from second to first floor to run Ethernet cables. It took close to 20 seconds to drill through ~9 inches with a 3/8” bit. That when I knew this SDS hammer drill is far quicker than a standard hammer drill. Well worth the money if you need it for more than one hole.Another great feature is it can hammer without rotating, so it’s much easier to move the starting hole without falling back into the initial hole. It’ll easily chisel out the edge of a hole without falling in to start a better hole location.It has three settings, rotate-only, rotate and hammer, and hammer-only. I use hammer-only setting to avoid the drill from initially walking if I’m not perpendicular, then rotate and hammer for a quick hole at any angle.It's a great drill. It has a lot of power. The only problem that I encountered twice. Was that I drill until the nose touched the ground and the drill bit got stocked. I had to unscrew it out with some pressure pliers. Everything else. It's great.Great tool for the price makes the job easyLike everything about it. Gets the job done!!! Removing tile from concrete floor with ease.I love this toolHandle brake to eze heating up to fast uses to many batteriesPara mi trabajo excelenteThis is a great SDS hammer drill. When getting this drill I figured I would use it from time to time, when I didn’t want to pull a electrical cord out to use my Bosch bulldog drill. But ended up using the Dewalt battery drill all the time being it’s light weight. So after five hard years of work I burned the first one up. So I’m on my second one now and hopefully will get five years of use with it as well.-JohnI first noticed the weight on this tool. It's not the lightest thing, but on first use, that's all forgotten. So much so that I screamed hallelujah and praise the lord... I don't even do religion. It's so good, my local pastor came to me and confessed HIS sins. Of course I blessed him, much like this tool has blessed me. Don't be afraid to take this power into your hands.At first I was looking at bigger machines in the $600 price range. The price of this thing came down to around $275 so I took a chance and boy am I glad I did. This thing drills through concrete like butter. It's just the right size for small jobs. I even used the hammer function with a 1" chisel to break up ice on my driveway this winter. It made really quick work with that. I run this thing with my 6 Ah battery and it goes for a long time.Produit très décevant pour un Départ!Ideal pour une utilisation occasionnelle!Mais pas conçu pour une utilisation journalière!A brisé 4 fois en 2 ans et la dernière fois ça a pris 4 semaines avant le retour de l'outil! Et il ne fonctionnait pas plus! Donc retourné au centre local Devant qui a fait la job très rapidement!Buena inversión lo acabo de recibir y lo acabo de utilizar para meter unos taquetes en unos colados y me sorprende,Lo compre sin batería ya que el precio del paquete con baterías se me hace demasiado elevado,Opte por comprarlo así y comprar la esmeriladora con 2 baterías 60 flexvolt y gaste la mitad de precio de lo que cuesta con las baterias xr, así tengo 2 máquinas y el doble de batería,Yo me dedico al ramo de remodelaciones e instalación y fabricación de ventaneria y dewalt me a servido muy bien en todo los aspectos y costos de las máquinas..Les dejo esto para ver si les llega a servirI gave up when using my regular hammer drill to drill through the basement wall 11 inches. My both arms was hurt from shaking a lot. Got this rotary hammer drill in and it took me less than 7 minutes to drill 1 inch hole to other side of the basement wall. My right arm is wonderfull. Just feel like you drill thru wood. Really nice job dewalt.
