Designed specifically for pneumatic (or air) reciprocating saws, Pneumatic Reciprocating Saw Blades use exclusive Starrett bi-metal unique technology. In controlled tests, bi-metal unique saw blades cut up to 20% faster and lasted 22% longer than five other premium blades.
Bi-metal unique technology joins two strips of high-speed steel wires to backing steel in a solid phase, using the principle of solid-state diffusion bonding. This technology is totally different from traditional weld or laser bonding, which relies on metal fusion as the union agent at the interface.
The proprietary solid-state diffusion process generates 170% more weld contact area compared to existing bi-metal high-speed steels. The result is significantly reduced fracture and breakage at the high-speed steel/ backing material interface.
The Starrett Pneumatic Recip Blade line includes three different blades for cutting metal: 18, 24 or 32 teeth per inch (TPI) and a variable pitch (14-18 TPI) multi-purpose blade for cutting composites, steel sheet and wood. In length x thickness x width, blades are 3-5/8 x .024 x 1/2 in. (92 x .6 x 13 mm). Each blade is available in packages of 5, 20, and 50.
