Intended for use on stationary circular saws for cutting natural woods and composite materials such as formwork, they enable simple to good cross and longitudinal cutting results. Thin kerf for fast and even cutting. Construction saw blades are suitable for initial installation when cut quality is less important and frequently reused woods are used.

Ribbed ventilation slots ensure the blade runs cooler, reducing bending and binding. All blades feature a 5/8-inch arbor with diamond cutout.
