Types of Diamond Drill Bits

The Impregnated Diamond Bits

As the name suggests, in the impregnated bit the crown matrix is impregnated with diamonds. The reason for this is as a grinding action accures on the crown while it is cutting through the rock, the matrix wears down, thus exposing the diamonds which in turn cut the rock.

Surface-Set Diamond Bits

The surface-set bit has diamonds imbedded in the surface of the crown. The depth that these stones are set depends on the size of the stones and will normally be about 2/3 of the overall diameter of the stone.

Polycrystaline Diamond Bits

These bits are produced by sintering together diamond particles at very high temperatures and pressure.
