Product Description
The 100mm DHD3.5-100 DTH drill bit is designed for quarrying and mining applications where efficient cuttings removal and drilling stability are essential. Reinforced with embedded premium PDC cutters and equipped with semi-ballistic carbide buttons, it delivers consistent penetration, enhanced gauge protection, and long service life in medium-hard to hard rock formations.
Embedded PDC Cutters for Small-Diameter Precision Drilling
The DHD3.5-100 DTH drill bit combines premium semi-ballistic tungsten carbide buttons with strategically embedded PDC cutters to create a durable hybrid drilling structure. The embedded PDC cutters reinforce the gauge area, reducing wear while maintaining accurate hole diameter throughout continuous drilling operations.
Its concave face design promotes efficient cuttings evacuation by directing broken rock away from the drilling face, helping reduce regrinding and improve drilling efficiency. Semi-ballistic carbide buttons provide a balanced combination of penetration speed and impact resistance, making this drill bit ideal for demanding quarrying and mining environments.
Designed for long service life and reliable performance, the DHD3.5-100 helps improve productivity while lowering maintenance and replacement costs.
