Evolution R12DCT 12 Inch Concrete Saw with Water Fed Dust Suppression (Aka Angle Grinder, Cut Off Saw, Masonry) Electric, No Gas, 4-1/2" Cut - Incl Premium Diamond Blade (Formerly R300DCT+)

I have used several different gas powered wet cement saws and still other wimpy electric saws. without water dust control or vacuum port options and honestly this is the best saw I've used for cutting up slab in a basement environment. It is electric so no CO2 and CO gas. It used a standard hose to wet the cut and pretty much eliminates all dust although the cement ladder water does spray up on walls behind the saw so you want to hand plastic or something to contain the spray and reduce clean up. Also, tape the plastic protection to the floor to help channel the water to the drain or contain it within the work area. The saw cuts well! It has a real nice feel to it and the wheels balance it out nicely. You can rock down into the cut and it really gives you control over the depth. Obviously you want to pay close attention to the depths of the saw if the pipes are just below the slab. It was actually quite powerful and only flipped the breaker once when I was pushing it too hard. No biggie. I had cut approximately 65-70 linear feet of cement slab so the blade may have been getting a bit dull. The saw cut through 3" of slab easily and could have done 4" slab no problem. Very, very impressed by the quality and price of this saw! I am a professional and I found it durable and reliable in the 2 days I've used it thus far. It doesn't seem like it will be giving up anytime soon. 2 minor qualms. One, one of the wheels came off during the cutting process. The wrench that comes with the saw slides into a holster under the trigger guard area so I pulled it out and used it to quickly tighten up the screw that holds the wheel in place. Two, the quick disconnection for the hose was a bit sticky. It didn't come with a rubber washer(no problem because I had one on hand) and it didn't quick connect, I had to pull and fight with it to get the connection loose. I will probably buy a new brass quick connection fitting to replace the plastic one provided. That being saw, you can't beat the price and the connection was leak free even if it was hard to disconnect (especially w/o the hose attached). Can't complain, this is a quality saw and very $70/day and I used it two days. $300 dollars is a steal. Evolution tools are good bang for the buck. I also bought a miter saw stand and a steel cutting chop saw and both feel very solid and high quality for the money spent.

I used it today to cut a 4 feet wide concrete wall way with 3/8” rebar and it does the job well. Also tried to cut a 60mm (2 and 3/8”) concrete paver— it is much easier to cut than the slab. All these are what I expected before ordering the tool. Highly recommended for a home owner for light concrete jobs! Don’t know what pro would say as I am not a pro nor a contractor. Good features: you Can connect your water hose to this machine which has a connector to run water to suppress 95+% of dust! Very desirable feature. Only R300+ model has this so make sure it is R300+ model. Two small wheels can support the tool during cutting concrete slab, reducing 90% fatigue you may have. It comes with a nice diamond blade so I don’t have to spend extra money on a blade. Lastly it is an electrical too, no gas engine. Something to mention also not so critical: the hose connector leaks as the O-ring does not fit or the connector does not have the right inner diameter. Manufacturer please fix this. It does not bother much but should not also water leak. The plastic storage recess cannot hold the wrench properly, plastic part may have been broken at factory as I didn’t break any parts. Overall, perfect for home owner whose likes to do small concrete job. All major functions work very well. Some minor things are there but won’t affect you much I give it a 5 star. If all issues are fixed I will give it 6 star.

Purchased this to help with a yard project. Neighbor was replacing his drivway, & I wanted the concrete for yard projects. I initially rented a walk behind saw to cut the drivway into larger slabs that were dropped off at my house. i've been using this saw to cut thenm into 2'x3' sections that will be used as replacement steps down a hill, & other retaining wall areas that don't require better looking blocks. The saw is easy to use & works well. The water cooling eliminates dust and the saw just works! i would purchase this again or recommend to anyone looking for a basic concrete cutting saw.

This saw has plenty of power for cutting concrete and stone. Let the blade do the work. If you keep it straight, meaning don’t bind the blade, it’ll cut like butter and not bog down. The water system works perfectly, keeping the dust at bay. Although it’s a heavy saw, the weight is distributed well and has good balance. The enormous motor starts up slowly, gets up to speed smoothly and the electric brake acts quickly to stop the blade. I run mine on a large generator because it’s a very heavy draw and couldn’t be run on my small solar powered system. You better have a full 20 amp circuit to run it properly. It really is a capable, well-designed masonry saw, except I wish they would have included a depth stop for cutting lines to a consistent depth. Evolution has made a pretty good, reasonably priced product here and I’d recommend it.

I bought this saw to cut a footing for a car hoist i am installing. I didn't want to rent because of all the hassel, and renting is almost the same price as this saw. I am absolutely amazed how well this saw performed. I cut a 4 foot square footing hole plus 2 waffle cuts. It took me about an 1hr of total cutting time. This was at full depth. So 25 feet of 4 ½ inch concrete. It didn't niss a beat, the blade is almost like new still. Saved myself huge money doing the cut myself, and i get to keep the saw. I wouldn't use this saw daily but as a backup or doing how jobs once in a while its amazing. A 20amp breaker is helpful, i didn't have any trips. 15amp may be an issue. Definitely spend the extra and get the wet saw. It hooks tona garden hose so no fancy connections needed. Highly recommend this saw.

I never write reviews, but after using this saw to cut a massive amount of concrete and a ton of hard granite rock I’m beyond impressed. The blade is nearing the end of its life after all the hard rock cutting but it hasn’t had a single issue, even after long uninterrupted cuts. I had rented a gas STIHL with a rock specific blade because I thought it would be faster, it wasn’t, I went back to the evolution saw. It will blow your 15amp breaker if you push it too hard, ideally use a 20 amp circuit. Make sure you have a heavy gauge extension cord as well.

This a fantastic saw. I’ve used it to cut concrete and rock and it works excellent. The water system works great keeping the dust down. It is the best value for money for any power tool that I have seen.

Good

I bought this for a patio job I made about 30 complex cuts for some 4-in brick and it easily did that so far very happy
