Description
Bi-metal unique® saw technology, a patented Starrett process, joins two strips of high-speed steel to backing steel utilizing solid-state diffusion bonding (rather than traditional weld or laser bonding) for 170% more weld contact area to reduce fracture and breakage. After initial use, the teeth develop a groove in the thin center of the backing material. As a result, the cutting stroke produces two chips that are more easily removed from the cut. In controlled tests, bi-metal Unique® cut 20% faster and lasted 22% longer than five competing premium blades. Starrett’s latest saw innovation is Dual Cut Jig Saw Blades. They are the first jigsaw blade with teeth that cut in both directions, virtually eliminating burrs on both sides of the cut. Dual Cut jigsaw blades are manufactured using bi-metal Unique® saw technology and have a Unified Shank® for use with both Universal and Bosch-style machines.
