Product Description

DC1420 PDC Dome Cutter for Heavy-Duty Rock Drilling

The DC1420 PDC Dome Cutter is engineered for high-impact drilling applications where durability and wear resistance are essential. Manufactured using advanced HPHT technology, it combines a premium polycrystalline diamond layer with a tough tungsten carbide substrate to achieve exceptional mechanical strength.

With a 14.07 mm diameter, 20.0 mm total height, and a 7.50 mm spherical radius, the DC1420 offers greater contact area and improved impact absorption compared with smaller cutters. This makes it particularly suitable for larger DTH drill bits operating in abrasive and fractured rock formations.

Applications

The DC1420 PDC Dome Cutter is widely used in:

-    DTH hammer drill bits

-    Open-pit mining

-    Quarry drilling

-    Water well drilling

-    Geothermal drilling

-    Foundation piling

-    Blast hole drilling

-    Hard rock exploration

Key Features

-    High-impact dome profile

-    Premium wear-resistant PDC layer

-    Strong carbide substrate

-    Excellent resistance to chipping

-    Stable cutting performance

-    Precision dimensional consistency

-    High bonding strength

-    Extended drilling life

Why Choose Our DC1318 Dome Cutter?

1.Technical Advantages

The larger geometry of the DC1420 allows it to withstand greater impact loads while maintaining efficient rock-breaking performance. Its optimized dome structure evenly distributes stress across the diamond layer, reducing localized wear and improving cutter reliability during continuous drilling.

Compared with conventional carbide buttons, the DC1420 delivers significantly longer service life, higher penetration efficiency, and reduced bit maintenance costs.
