sahanteräisyys

Sahanteräisyys refers to the characteristic jagged or serrated edge found on many types of saw blades. This pattern of teeth is crucial for the effective cutting of materials. The shape, size, and spacing of these teeth vary depending on the intended use of the saw, whether it's for wood, metal, or other substances.

The principle behind sahanteräisyys is to create a series of small cutting edges that remove material as the blade moves. Each tooth acts like a miniature chisel, shaving off small particles. The sharpness and angle of these teeth, known as the tooth set, influence the speed of the cut and the quality of the surface finish. A finer sahanteräisyys generally results in a smoother cut, while a coarser one allows for faster material removal.

Different tooth geometries exist to optimize cutting performance. For instance, some teeth are designed with a specific rake angle to reduce friction and improve chip removal. The Gullet, the space between the teeth, also plays a role in carrying away sawdust or metal shavings, preventing the blade from binding. Maintaining sahanteräisyys through sharpening is essential for a saw to function efficiently and safely.
