Diamond core drill bits differ from other drill bits because they consist of a steel casing that has diamonds embedded on the cutting edge of the bit. Diamonds are one of the hardest substances known to man, and they work very well to cut through harder materials that would destroy a metal-only drill bit.
 
The main working parts of Diamond core drill bits - drilling segments are made of Cobalt-based formula, and superior grade diamond to match, the quality is at least twice better than normally used Iron base formula by other most producers.
