Alternate top bevels (ATB)
Designed both to rip and to crosscut efficiently, ATB-shaped teeth are common in all-purpose blades. In the past, this design did not do as well when ripping, but this quality is less of an issue with newer thin-kerf ATB blades. ATB blades are sharp but are typically less durable than other tooth grinds, which results in a shorter life. Many manufacturers are now integrating specialized carbide into their blades to overcome this shortcoming.
Best uses: ATB blades perform well in circular saws and miter saws whether cutting LVLs, I-joists, flooring, oriented-strand-board (OSB) sheathing, or pine studs. Some versions can even be used to cut aluminum and steel.
