Masonry saws are not usually something you need, unless you need to access something under a concrete slab, or in the case of removing an industrial machine, sawing the bolted feet out of the concrete floor. There are a number saws by type and by job expected. The following will help you get to know these saws, in case you ever need to rent or buy one to use on a project.
Handheld Circular Saw with Various Cutting Blades
This portable type of masonry saw is portable and lightweight enough for you to cut both vertical and horizontal cuts in concrete. Ergo, if you have to cut a concrete wall, then you can do that just as easily as removing a concrete slab from a concrete floor. The blades also cut brick and stone, which are useful in the event that you need to repair a brick wall or cut pieces of stone to create a stone walkway.
A Walk-Behind Masonry Saw
When you cannot bend down or crouch, or you cannot use two hands on a masonry saw, this is the solution. The saw blade is attached to a base with wheels and a long extended handle to help you push the saw from a standing position. This type of saw may only cut concrete slabs that are on the horizontal plain.
Angle Cutting Saw
Cutting concrete, rock, brick, or stone at an angle is a nightmare, unless you have an angle cutting saw. This type of masonry saw allows you to set the degree angle at which to cut the hard materials in question. You will have to measure the space you are trying to fill and then make sure you know how to use the saw to cut that angled piece. If you have never used this style of saw, and/or you are hesitant about doing this task yourself, hire a professional mason for the job.
Reciprocating Saw with a Diamond Blade
Also known as a "saws-all," this type of reciprocating saw can cut through concrete and other stone-like surfaces, but only if you have the right blade. The other caveat is that you have to have a hole or an edge to start with, because this saw cannot saw its own hole into solid concrete. The blades for these saws are not designed to manage or do that. A diamond blade or masonry-specific blade is sufficient.
