Buying a used concrete saw for cement concrete masonry work comes down to a simple problem: how much capability do you get for the money, and how much risk comes with the hours already on the machine. The Diamond Products CORE CUT CC2500 puts that trade-off right in front of you. It's listed at $3,500, and if you're in the market for mid-size concrete cutting equipment, this unit deserves a close look.
Quick verdict: The CORE CUT CC2500 is built around a Honda CX670 gasoline engine rated at 24.0 horsepower. The caveat is that this specific unit is used and shows 1,939 hours, so you're buying a machine with measurable wear already on it. For a crew or contractor comfortable with used gear, the mechanical package is the main draw.
Who it suits: This saw fits a contractor or experienced operator with regular large-area cutting needs. Its design helps reduce physical strain during long passes. If your jobs are occasional, small, or mostly on thin slabs, this is likely more machine than you need.
What stands out from the listed details: The headline specs are the 26-inch maximum blade diameter and the 10-3/8-inch maximum cutting depth. With a blade that size and that depth, you can cut through thick concrete efficiently. The saw comes standard with a crank raise-and-lower assembly, and a hydraulic control switch is listed as optional if you want faster depth changes.
Diamond Products CORE CUT CC2500 Self-Propelled Concrete Saw

This used unit is the exact saw under consideration. It is a gas-powered, walk-behind self-propelled model from Diamond Products, with a Honda CX670 engine rated at 24.0 horsepower and showing 1,939 hours. The saw can accept a blade up to 26 inches in diameter and cut to a maximum depth of 10-3/8 inches. The standard depth adjustment is a crank assembly, with a hydraulic control switch available as an option. The unit is described as running and cutting as it should. The limitation is the used condition and the hours already on it, which any buyer must weigh into the $3,500 price.
Meaningful trade-offs: The central trade-off is the listed hours versus the asking price. A used concrete saw with those hours will have wear on the engine and drive components, so you're taking on some risk that a new unit wouldn't carry. The standard crank lift is functional and simple, but if you want the faster hydraulic adjustment, that will cost extra. The convenience of the drive system only matters if the engine and drive components are in good shape.
Bottom line: The Diamond Products CORE CUT CC2500 is a capable concrete saw with a strong specification sheet. The large blade capacity and deep cutting range cover the needs of many concrete cutting projects. If you're comfortable purchasing used equipment and accepting the hours already on this unit, this saw offers a solid balance of capability and cost.
