ProsDiesel-powered at 71.1 HPSuper reliable buildLiquid-cooledSpeed up to 200’/minGives true blade speedOne-handed operationConsBreaks the bankThe Diamond Products CC6571D is one of the best self-propelled concrete saws on the market, period. It’s diesel-powered with a turbo-charged 4-cylinder, 2.6L, 71.1 hp Kubota V2607 engine and can cut through concrete like the champion that it is. One of the best features on this bad boy is that it is liquid-cooled.
This not only extends the life of the saw but it also results in much higher productivity. And perhaps the second best quality of this saw is its incredibly strong frame. Diamond Products even claims it is the “strongest frame on the market.” For its size, it’s really easy to maneuver and it also has the ability for a user to operate it one-handed.
With propelling power to move it at a speed of 0-200’/min, it’s one of the fastest on the market as well. It also has an easily visible blade shaft tachometer positioned to give you true blade speed. It also has an hour meter and is equipped with a parking brake.

Buying Guide
What to look for before you buy
Blade Diameter
A 14-inch blade cuts about 4-5 inches deep — enough for most sidewalk and slab work. An 18-inch blade reaches 6-7 inches for thicker pours. Walk-behind saws with 20-24 inch blades handle deep road and utility cuts.
Power Source
Gas-powered saws are standard for outdoor flatwork. Electric saws work indoors or in enclosed spaces where exhaust is a problem. Hydraulic saws mount on skid steers for heavy roadwork. Match the power source to your job conditions.
Our Verdict
The MK Diamond MK-1613H is the best overall concrete saw. The CORMAC CQ480H is the best value.
