Electric Wall Grooving Cutting Machine Chaser 110V for Slotting Brick Granite Marble Concrete Grooves With 5Pcs 5Inch 133mm Diameter Saw Blades Dustproof and Line Infrared Sighting

Works great !

The water pump kept the dust to a minimum, so cleanup was easy with a shop vac. Instructions were written by a non-English speaker, but I figured it out. It cut a straight groove for my conduit to run to my new kitchen island. Money well spent. The rental company would have charged almost as much for a one day rental of a gasoline powered behemoth with a single blade, hence multiple grooves to lay a conduit. This machine, on the other hand had five parallel blades and made a meet groove in one pass. Laser guide. We’ll built. Heavy.

Quality product that gets the job done.

Was needing to install at my mother in laws kitchen island electrical. The house is on a slab so I had to slot the concrete to do the job. I ordered diamond blades if needed. I used the saw with the blades it came with. Never needed the diamond blades. The saw did an excellent job. I would highly recommend!

Ran the saw with water. Blades installed backwards. Corrected them and did maybe a foot of cuts then it stopped smoked and died. DO NOT BUY!

Did a good job and held up for eight 10-foot grooves in concrete slab. Draws a lot of power, you need a 20 amp circuit. Not fancy, but everything worked. My only criticism would be that the stated "41 mm" cutting depth is more than what we got, more like 35 mm at most.Totally disagree with the other reviewer who removed the water pump system after ten minutes. We found it makes a huge difference and works well (comes with an extra nozzle, which we didn't need) -- five blades working at once kicks up a lot of dust. No instructions, though (submerge the pump in a bucket).

I had a drainage problem with my driveway flooding my new barn, and I was looking for a way to divert the water away from the barn. Using this tool I was able to cut a 1" x1" (25x25mm) channel, about 57 ft (17.4m) across the concrete driveway, in about seven hours of work. I'm pretty happy with that, as I am fairly sure that any other solution would have been more expensive. The good: it came with minimal instructions, tubing and pump for water cooling, and (unexpectedly) a set of 5 blades! The bad: it came with minimal instructions, required a lot of force to cut through the concrete, and there was no provision to vary the depth of the cut at all. The shoe on the bottom does not adjust to make shallower cuts. It will tend to wander as it cuts, so you need to fashion a guide fence. I used a 2x8 board with a lot of weight on top of it. I powered it on its own 20A breaker, which it popped twice under heavy load. That may sound like a lot of criticism, but it was a hard job, and it performed. All in all, I am pretty happy with the results, and it's a pretty good tool.

Heavy duty, great work
