  • what is a diamond saw blade
  • A diamond saw blade is a circular steel disc (core) with an edge of metal 
    bonded diamond segments which act as cutting teeth. The edge of the 
    diamond can have segmented, continuous rim or serrated diamond cutting 

    sections.  The blade core is usually, but not always,  a ground flat, steel disc.


    Some cores have sound deadening features. Segmented blades are usually 
    slotted ( “gullets”)  which provide more efficient cooling by allowing water or 
    air to flow between the segments. Gullets also allow the blade to flex under 
    cutting pressure.  Most blade cores are levelled and tensioned at the factory 
    for the specific rpm the blade will be operated at.  Correct blade tension 
    allows the blade to bend under cutting pressure and “snap” back into 
    position.  Diamond segments or rims are mostly composed  of diamonds and 
    metal powders. Diamonds used in blades are virtually always synthetic
    diamonds varying in size and toughness. In the manufacturing process, the 
    metal powder and diamond grit mixture is hot pressed at high temperatures to 
    form a solid metal alloy (called the bond or matrix) in which the diamond grit is 
    retained. The segment or rim is slightly wider than the blade core to reduce 

    cutting friction from the steel core.


    Several different manufacturing methods are  used to assemble segmented 

    diamond saw blades


    Brazing.

    Silver brazing material is placed between the segment or rim and   the core. 

    At higher temperatures around 650 to 700  degres centigrade, the solder 

    melts and joins the two parts together.


    Laser Welding.

    The diamond segment and blade core are welded together by a laser .


    Mechanical bond.
     A notched, serrated or textured blade core may be used to “locate” the 
    diamond rim or segments onto the edge of the blade. Mechanical bonds 
    usually also include brazing or other metallurgical bonding processes to hold 
    the rim or segments in place.
