Starrett Blue Stripe Hacksaw Blades - Bi-Metal Unique tb30e
	Starrett Bi-Metal Unique? technology joins two strips of high speed steel wires to a backing steel in a split phase, using the principle of solid state diffusion bonding. Bi-Metal Unique technology is totally different from traditional weld or laser bonding processes that rely on metal diffusion as the union agent at the interface. The proprietary (patent pending) solid-state diffusion process generates170% more weld contact area compared to the existing bi-metal high speed steels, that results in significantly reduced fracture and breakage at the HSS/backing material interface. The unique technology alters the blade area engaged in the cut for Multi-Edge Performance?. The exceptionally strong teeth develop a groove after initial use. This produces dual chips that are more easily removed from the cut. For applications utilizing coolant, more of it flows to the cutting surface. This is the Split-Chip Advantage?. The result is faster cuts and longer blade life - clearly demonstrated by exhaustive series of recent tests comparing Unique hacksaws blades against premium competing blades
