Set (saw)

set saw blade

In the case of saw blades, set is the bending of the teeth alternately to the right and left.

Free cut when sawing through set teeth

So that a saw does not get stuck in the cut, but rather cuts itself free , the saw cut must be wider than the blade. Contraction is one of several ways to achieve this. The teeth are bent alternately to the left and right at a third to half of their height (crossed against each other). The overhang must be the same on both sides, otherwise the saw will wear unevenly and run.

The height and width of the set depend on the purpose of the saw. For example, the precision saw and offset saw are set only slightly for a clean and fine cut and good guidance, while the cutoff saw and chopping saw for high cutting performance are wide.

There are various hand tools for setting new saw blades for the first time, for setting individual bent teeth or for setting the entire saw. Setting has to be done before sharpening. Saws with hardened saw blades or teeth cannot be re-set as the teeth will then break off. In industrial production, saw blades are set using machines.

Setting tools

Bending iron

Bending iron

Bending irons consist of a steel plate with a handle. The plate has incisions of different sizes for different tooth sizes, with which the teeth are gripped and bent. Since even setting with the setting iron requires some experience, there are versions with stops where the setting width can be adjusted.

Cabinets with cabinet pliers

Setting pliers

In the case of setting pliers, the depth of engagement and the deflection can be fixed using stops and adjusting screws. With them, the saw blade is gripped by the tooth and this is bent out when the pliers are closed.
