Product Description
The 90mm DHD3.5-90 DTH drill bit is reinforced with embedded premium PDC cutters and features a concave face with an enhanced 8-gauge-button layout. Designed for quarrying and mining, it provides excellent gauge protection, reliable drilling stability, and extended service life in abrasive rock formations.
Embedded Premium PDC Cutters for Maximum Wear Resistance
The DHD3.5-90 DTH drill bit combines premium 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 and maintaining consistent hole diameter throughout extended drilling operations.
Compared with standard 90 mm configurations, the optimized 8-gauge-button layout provides stronger peripheral support and better resistance to gauge wear. The concave face improves drilling stability and cuttings evacuation, while the semi-ballistic carbide buttons deliver an excellent balance of penetration speed and durability.
This design is well suited for quarrying, mining, and other demanding rock drilling applications where reliable performance and long service life are essential.
