Angle grinders can adapt to a number of cutting scenarios, such as for use with concrete patio pavers. You can attach a diamond cutting wheel to a 4-inch angle grinder and use it to cut patio pavers for small scale projects, such as backyard patios where you only need to cut a few pieces, or for cutting around electrical outlets and other corners. The ease of use with the angle grinder makes it ideal for taking care of small cuts without the need for heavy equipment.
Miter saws, also known as chop saws, can be used for angle cuts and edges where you need to cut the concrete patio pavers at odd angles. You can also use a chop saw to cut the pavers in half, or to shave off sections of the paver as needed. While you need to use a diamond blade, the plunge effect of the chop saw allows you to easily and effectively shave off sections of pavers as well as set the angle of the blade to cut the pavers as needed.
Similar to circular saws, handheld stone cutting saws come in both dry and wet formats, depending on your personal preference and budget. Home improvement versions come with a 4-inch blade and are small enough that you can handle them with one hand, but there are also commercial versions that come with a 14-inch blade that require two hands to operate. They can cut a variety of pavers similar to an angle grinder, but have more control and usually have guides that can be used to help make straight cuts.
Wet saws are the preferred method for cutting bricks, blocks and pavers. While in the past they were only available to contractors, these days you can rent wet saws at any home improvement store. You can find them in a range of sizes from those with 4-inch blades, 8-inch blades and up to 14-inch blades for large-scale paver projects.
