Method of manufacturing a segmented diamond blade

A cutting blade having a circular core with an outer periphery having gullets formed thereabout and with a continuous outer rim thereon, said continuous outer rim having notches therein proximate said gullets, said blade being formed by a method comprising the steps of:

• introducing a bond powder mixture onto said core to form a continuous uninterrupted outer rim, said bond powder mixture including metal particles and hardened cutting particles;
• after said introducing step, bonding said core to said continuous uninterrupted outer rim by heating said continuous uninterrupted outer rim and said core to a preselected temperature;
• and
• after said bonding step, forming notches through said continuous uninterrupted outer rim to remove portions of said outer rim and portions of said core to form a segmented outer rim.

A method for producing a cutting blade having a core and a segmented outer rim comprising the steps of:

• introducing a bond powder mixture onto said core to form a continuous outer rim;
• bonding said core to said continuous outer rim by heating said continuous outer rim and said core to a preselected temperature, wherein said bonding step includes the steps of,
• heating said core and outer rim to an initial bonding temperature for an initial bonding time period;
• and
• thereafter, heating said core and outer rim to a final bonding temperature for a final bonding time period;
• and
• forming notches through said continuous outer rim to remove portions of said outer rim and portions of said core to form a segmented outer rim.

• bonding said core to said continuous outer rim by heating said continuous outer rim and said core to a preselected temperature;
• and
• forming notches through said continuous outer rim to remove portions of said outer rim and portions of said core to form a segmented outer rim, wherein said bond powder includes at least two metals and wherein said core and outer rim are heated during said bonding step to a temperature between melting points of said two metals.
