      Spherical Shaped Cutters for Down-the-hole Drilling

      Features:
      • Widely used for down-the-hole (DTH) drill bits.

      • With high impact resistance and excellent wear resistance. 

      • The wear resistance and strength is improved greatly because of the special design of the diamond layer.

      • Optimizing the stress between the diamond layer and tungsten carbide substrate by the double-layer. diamond design, improving the impact resistance and service life greatly.

      Features:

      • Widely used for down-the-hole (DTH) drill bits.

      • With high impact resistance and excellent wear resistance.

      • Optimizing the stress between the diamond layer and tungsten carbide substrate by the double-layer. diamond design, improving the impact resistance and service life greatly.

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

      Performance:

      • Wear Resistance: ★★★
      • Impact Resistance: ★★★★★

      Recommended Applications:

      Used on down-the-hole drill bits for mining high hardness formations
