●Widely used for down-the-hole drill bits,with high impact resistanceand excellent wear resistance.

●The wear resistance and strength is improved greatly because of thespecial design of the diamond layer.

●Optimizing the stress by the double-layer diamond design, improvingthe impact resistance and service life greatly.

●The tungsten carbide DTH drill bit is easy to scrap because of thelack of wear resistance, the PDC DTH drill bit features higherstrength&hardness&wear resistance, longer life(10-15 times oftungsten carbide insert) and lower drilling cost.

Wear Resistance: ★★★

Impact Resistance: ★★★★★

Used on down-the-hole drill bits formining high hardness formations.
