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.

  • 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.

  • 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
