What is the term for the degree that the teeth of a hacksaw blade are pushed out from the center?

The degree to which the teeth of a hacksaw blade are pushed out from the center is called "set." This refers to the intentional bending of the teeth away from the blade's centerline. The purpose of the set is to create a wider kerf, or cutting path, than the thickness of the blade itself. This allows for better clearance of the blade during cutting, helping to prevent it from binding in the material being cut.

A hacksaw blade with an appropriate set will cut more efficiently, producing less friction and heat buildup, thus prolonging the life of both the blade and the cutting device. The concept of set is crucial for achieving an effective and precise cutting action, especially in various materials and thicknesses.

Pitch refers to the number of teeth per inch on the blade, rake relates to the angle of the teeth in relation to the cutting direction, and offset generally refers to the distance that a part is displaced from its original position; none of these accurately describe the feature of teeth being pushed outward from the center in the context of a hacksaw blade.
