Tooth pitch, which for metal-cutting saws is usually measured in teeth per inch, varies according to the cross section and the type of material to be cut.
Tooth Forms
N-tooth (standard)
The normal tooth is best suited for sawing of small-chip materials with high carbon content, such as tool steel or cast iron. It is suitable for a wide range of applications, including thin cross-cuts and materials with thin-walled cross sections.
Variable-tooth
The hook tooth with a positive rake angle can be used for all kinds of steel especially for long-chip and hard-to-cut materials, for example construction steel and hardened steel, as well as high alloy materials.
Tooth Set
"Tooth set" means the alternating lateral bending of saw teeth. It enables the saw band to cut freely.
Raker Set
The raker set (left-right-straight) is useful for all types of steel, especially for cutting thicknesses of 5mm and more.
Variable Set
In a variable set there is one unset tooth per toothing interval. The rest of the teeth are bent alternately left/right. This set facilitates low-vibration and low-noise cutting.
Wave Set
The wave set is well suited for thin materials up to 5mm, such as sheet metal, thin-walled tubing and cross sections.
