DEWALT Wet Tile Saw, Masonry, 4-3/8-Inch (DWC860W)

I very rarely take the time to post a review here on Amazon and I buy a ton of stuff from them. I bought this saw to cut the cement board for my BBQ island project I am working on. I will probably end up using about 20 sheets of the 1/2" Hardibacker 500. I have read a ton of reviews about cutting this stuff and all of them stated that it was a pain to cut and the dust is extremely bad for your health. A lot of people end up putting a very low tooth count blade on their circular saw and wearing a proper 2 stage dust mask but the dust goes every where. After a ton of research I found this saw on Amazon. The saw arrived today and I was cutting with it this afternoon. Cutting the 1/2" Hardieboard was no kidding like cutting butter with a very hot knife. The cut edge is very smooth and it was really easy to follow my cut line. Like others have said, this saw feels very well built with one noted exception that many others have mentioned. The water line fitting hat sprays water on to both sides of the blade is plastic and feels like the same plastic used in drip line irrigation fittings. I won't dare to guess how long it wil last but I would be surprised it itmakes it a year. When it breaks I plan on using 1/4" copper tubing to make a replacement. The water hookup involves screwing a plastic flow restricter to the end of your water hose. For better control of stopping the water eyed I would recommend putting a small shutoff valve to the end of your hose and then attaching the flow restricter to the shutoff valve. As far as the blade arbor being an odd size I just have to say that there are quite a few 4 1/2" blades that already have the arbor reducing adapter in the blade. Those adapter can be removed from those blades and pressed into a 4 1/2" blade of your choosing. Overall I would rate this saw a 4.9 out of 5 stars just due to the plastic water fitting. I would purchase another in a heartbeat If I ever need to replace this one.

Bought this instead of the usual table slide tile saw because I knew I'd need some flexibility. Besides who needs another unitasker in the tool box? Saw Saw works great. A lot of comments about how easy it is to break the water injection assembly but given where it's placed it really shouldn't be much of an issue (yes a metal assy would be nicer). Cut the porcelain tile shown and it cuts with very, very little chipping - provided you watch your speed at the beginning and ending of the cut. Jig Making a good jig is critical unless you have special skills with a circular saw. Mine is a short term model but it clamps and provides a straight edge for the saw to ride against. So those halved width tiles have cuts that are nice and straight. Jig is also critical because the water tends to puddle and obscure the cut line. Predefining the cut line with a jig allows you to concentrate on keeping proper speed and not worrying about if you are on or near the line. Other - After one cut your crotch will be soaked. A lot of blowback at crotch level when using the water. - Power and water hoses tend to get tangled up as you go along though that's probably just me. Overall, very happy with it's performance.

Works well for cutting pavers, bought this to make angled cuts (20+) for a 65sq foot patio and it cuts through the material like butter with a 4 1/2in diamond blade. Cut quality is decent enough for edge cuts though the cuts will be hidden with poly sand. Wet cut function works well with a garden hose set to very low flow. Was originally going to buy a cheapie but have had good luck with DeWalt products over the years. I can imagine the tool will work even better on thin tiles.

The actual saw itself works fine the attachment however to convert this into a wet saw is absolute junk made out of plastic it broke three times I fixed it using epoxy in adding an email in with the epoxy to strengthen it now I'm looking for this piece made out of metal you wouldn't think it would be a big deal to add that for the cost. I would even pay more

I was concerned when I got this saw since there were some slightly negative comments regarding the water coupler/sprayer. I needed to cut several cordierite kiln shelves and wanted clean precise cuts while keeping the dust down. I considered buying the cheapest fixed blade table top saw, but I’m glad I purchased this saw. Besides cutting the cordierite shelves, I’ve used the saw to trim off the broken edges of a stone table. The motor is powerful enough to deal with the full cutting depth of the materials I needed to cut, the water connector provided the right pressure to keep the blade cool and eliminate stone dust clouds, and the built in safety breaker in the cord gave me the confidence that I wouldn’t be electrocuting myself. I think if I were doing small tile cuts, I’ll still need fixed table saw style cutter, but the circular rip saw configuration makes this a really handy and exceptional tool in my kit. Regarding the pictures, the stone table top on the propane fire pit is 3/4” thick and the additional thickness is an aluminum honeycomb 3/8”. With adhesive the thickest section I was cutting just over 1 1/2”, I had to use other tools the finish the job, but this saw did the bulk of the cutting thru stone, construction adhesive and aluminum. The pictures of the cordierite shelving show the clean edges of the cut, with the exception of where I paused to change my position, which resulted in the tool mark. Regarding my concern for the water coupler, it survived my use of this saw thru a couple projects. I also found that you can get replacement parts, including the water coupler online.

I was so excited to get this saw and use it on some 3cm countertop material. Was disappointed very quickly. Front of baseplate and back of baseplate did not line up with blade as I tried to get it to follow my clamped guide. I realized quickly that only the front was going to be against my guide. I had water turned on all the way and made my first cut, about 26". The cut was great but the saw wasn't wanting to track along my guide properly. I set up for a long cut across the back and made about 3' of the cut when I started hearing a loud popping noise and then got a whiff of the undeniable smell of burning brushes. Soooo disappointing. I had high expectations because the blade is 4 ³/⁸" and will cut at a 1 3/8" depth which is plenty for the countertop, but I am very disappointed with this tool. I can't express in words as to how disappointing all this is to me. I have used DeWalt tools for many years and this one is well below standards for DeWalt.

Small, lightweight, yet powerful, this tool goes right through all the tiles I've used it on. With the water connected, the blade shows very little wear after tiling a kitchen back-splash, a master bath, and an exterior entry way. Get one, if you have any tiling to do. It would be nice if the blade was nearer the end/edge of the saw, so you could cut into tighter spaces.

This would have been a perfect tool if they had built the water supply system as robustly as the saw. The cheap plastic pressure regulator blew apart on the first job. I ended up fixing it with gorilla tape to finish the first job I was on. Also, the plastic mechanism that attaches to the saw and sprays water the blade is flimsy and crappy and the plastic valve is useless, it doesn't stop the flow of water, so the saw just leaks water the whole time unless you turn the water off between cuts. Who knows how long this piece will last before breaking completely. I would have happily paid $20 more to have these two components made out of aluminum and with a proper valve so that they last and so that the water can be turned off at the saw when not cutting. I have replaced the regulator with a $10 metal gate valve that is garden hose female end to garden hose male end and keep the valve just barely cracked open to simulate the 5psi that the regulator feeds. I suggest you buy one of these, or at least have some tape on hand when first using the saw if you want wet cuts. I'm not sure how I'll go about improving the crappy nozzle/valve that attaches to the saw, but when that poops out, this is essentially an overpriced dry cut masonry saw. Also of note, I wish that the fence on the saw also covered the left side of the blade like a normal.circular saw does so that it could be ran against a square. It can be done from the other side, but it is very inconvenient, especially with the saw motor hanging over on that side. Would I buy it again? Yes, because it's about the only option for a saw like this with wet cutting capabilities, but I'm not satisfied with it considering it could have been a great tool had Dewalt not pinched pennies on the water system.
