Totally different from other methods of producing bi-metal saw blades, Starrett Bi-Metal Unique™ Technology joins two strips of high speed steel wire to a backing steel in a solid phase, using the principle of solid state diffusion bonding.
Massive increase in resistance to tooth breakage and fracture. Unique blades feature 170% more weld contact area through the solid state diffusion bonding process. This ensures exceptionally strong teeth.
Smoother, faster cuts. Multi Edge Performance and the Split Chip Advantage generate thinner chips which are more quickly and easily removed from the saw cut. In tests, Unique blades proved to be typically 35% faster than directly competing products.
Longer blade life. The exceptionally strong teeth, Multi Edge Performance and Split Chip Advantage ensure that Unique blades last an average of 35% longer than competing blades.
Lower cost per cut. The increase in resistance to tooth breakage and fracture, smoother, faster cuts and longer blade life all combine to guarantee one simple benefit - lower cost per cut.
Starrett Bi-Metal Unique™ Saw Technology is currently available in:
Bi-Metal Unique™ Safe-Flex Hand Hacksaw Blades.
Unified Shank Jig Saw Blades.
M42 Bi-Metal Band Saw Blades in widths up to and including 19mm / 3/4".
Two strips of high speed steel wire are joined to the backing steel in a solid phase.
Traditional bi-metal blades feature one high speed steel wire, electron beam welded to the backing strip - picture one.
Unique blades feature two wires, joined laterally to the backing steel in a solid phase, providing 170% more weld contact area - picture two.
After initial use the soft backing material in the centre of the blade will wear away, forming a groove which acts as a natural chip breaker and providing the blade with multiple cutting edges - Multi Edge Performance.
The multiple cutting edges produce thinner chips that are more easily removed from the saw cut - The Split Chip Advantage.
