The R12DCT electric concrete saw combines OSHA-compliant dual water dust suppression with a powerful 15A motor and a premium 12” diamond blade, delivering up to 4.5” cut depth for masonry, concrete, and steel-reinforced materials. Designed for professional durability and ease, it features a wheeled skid plate for reduced operator fatigue, Power Protect technology for enhanced longevity, and a 3-year warranty, making it the ultimate tool for clean, efficient, and reliable cutting on any job site.

## Description

Born to conquer the professional job site, the R12DCT electric concrete saw (Previously known as the R300DCT+) is the perfect machine for the pro’s when effective dust control is a must. It has an impressive cut depth of 4-1/2” making this one of the deepest cutting 12” machines on the market. The built-in dust suppression features dual sided water delivery, armoured hose routing & robust brass hose connection and is compliant with OSHA regulations. This saw comes armed with a 12” premium diamond blade packed with 35% more diamond* and features a multi-compound cutting edge designed to cut faster, cleaner & for longer. The high torque 15A electric motor delivers consistent peak power and stops the machine from slowing down under heavy load making quick work of tough materials. It starts first time, every time and does not emit any harmful fumes making this suitable for use in enclosed spaces. Plus, you don't need to worry about expensive fuel or servicing allowing you to focus on the job. The wheeled skid plate takes the strain out of long, ground level cutting and also allows you to put the saw down while the blade is still spinning. This saw utilises our Power Protect Technology which protects internal parts from dust & water ingress making it fit for use in the most demanding environments and comes backed by a 3 year warranty.

Review: High quality saw, with a few minor set backs.. - 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.
Review: Perfect product for a homeowner - 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.

### ⭐⭐⭐⭐⭐ Great Purchase, works well
*by M***M on December 12, 2025*

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.
