Lenox 21077 S656R 6" x 6T Wood-Cutting Bimetal Reciprocating Saw Blades

The Lenox Bi-Metal Reciprocating Saw Blades contains Power Blast Technology refers to a high speed blasting process known as peening, which is applied to the tang and cutting edge of reciprocating saw blades to reduce breaks and increase durability. By blasting the cutting edge and tang of the blade, a layer of compressive stress is created on the surface of the blade in the areas that receive the most abuse. This compressive stress reduces the formation of cracks which causes blade failure. The process is commonly used in the aerospace and automotive industries to strengthen steel and has been used in manufacturing Lenox band saw blades.
