Continuous rim blades have softer bonds for cutting hard materials such as tile, porcelain, granite, stone, glass,and other materials that can chip easily. These blades don’t have individual segments but instead have a solid, continuous rim or edge. Most continuous rim blades are designed for wet cutting applications, providing the smoothest, chip free cuts.
These blades are most commonly available in 4” to 14” diameters. The smaller, 4” to 5” diameter blades are often used in hand-held grinders while the larger sizes are often used with circular saws and tile saws.
There are also variations of continuous rim blades. The J-slot design is one variation that has J-slots around the edge of the blade to help dissipate heat for increased durability, extended blade life, and faster cutting speeds. Additionally, there are J-slot continuous rim blades available for dry cutting applications.
