Both abrasive and diamond blades are available for cutting concrete and masonry products. Abrasive blades are also available for cutting steel or ductile iron. Diamond blades can also be purchased or rented for concrete cutting. The advantage of the diamond blade is that it's narrower so it cuts faster and produces less dust. It also retains its full diameter unlike abrasive blades which wear down as they are used, so your depth of cut will be more consistent with a diamond blade.

If you need to cut in a basement, you do have other options in addition to this saw. A gas cutoff saw doesn't work in a basement environment unless it is a walk-out basement. The carbon monoxide fumes settle to the floor and by the time they reach a higher window it's too late to prevent asphyxiation. If you use an electric saw, you can't use water to hold down the dust (or else you'll get electrocuted). While the dust isn't toxic it can get all over and make for a difficult cleanup task, especially in furnace duct work. But it's an option as long as you wear a suitable dust mask. The ideal way to saw in a confined space is to rent one of our pneumatic concrete saws. They are available in walk-behind or hand-held versions. They utilize an air compressor which is located outside of the room. Air hose then feeds the saw through an open window. There are no fumes, no electricity, and you can use water to control the dust. The only disadvantage is the higher rental cost. For info on these options click on the following links to read more about them:
