ABSTRACT:
A saw blade possesses a base element onto which boron nitride particles are applied in the cutting region. The boron nitride particles are bonded by means of a metallic bonding layer, which preferably consists of nickel or a nickel alloy with a Vickers hardness of at least 600 HV. The bonding layer is preferably deposited galvanically. The boron nitride particles advantageously possess a particle size of approximately 0.5 to 0.8 mm, preferably approximately 0.6 to 0.7 mm. The saw blade possesses particular advantages for use as a reciprocating saw blade for sawing GGG cast iron pipes with a cement lining and fiber-reinforced cement jacket, resulting in considerably improved cutting performance and service life.
