Starrett BS228-5 Bi-Metal Unique Straight Metal Cutting Pneumatic Reciprocating Saw Blade, 0.025" Thick, 18 TPI, 3-5/8" Length x 1/2" Width (Pack of 5)

Starrett offers a line of bi-metal unique saw blades for the pneumatic reciprocating saws widely used in auto body shops, metal fabricating and other applications. Pneumatic saw blades are manufactured with bi-metal unique saw technology for faster cutting longer blade life. Bi-metal unique saw technology, a patented Starrett process, joins two strips of high speed steel to a backing steel utilizing solid-state diffusion bonding (rather than traditional weld or laser bonding) for 170 percent more weld contact area, to reduce fracture and breakage. After initial use, the teeth develop a groove in the thin center of backing material. As a result, the cutting stroke produces dual chips that are more easily removed from the cut. In controlled tests, bi-metal unique cut 20 percent faster and lasted 22 percent longer than five competing premium blades. Straight shape, round tip. 18 TPI. Measures 3-5/8-inches length by 1/2-inches width by 0.025-inches thickness.
