Spiral profile for broken formations
Six design advantages behind the Four-Wing Spiral PDC Drag Bit.
01 / 06 Four-Wing Balanced StructureThe four-wing layout distributes cutting loads more evenly and improves drilling stability. | 02 / 06 Spiral Curved Blade ProfileThe spiral blade geometry supports efficient cuttings evacuation and smoother drilling in broken formations. | 03 / 06 1613 PDC CuttersLarge 1613 PDC cutters provide aggressive cutting action and good wear resistance. |
04 / 06 Stable Drilling in Fractured FormationsThe blade and cutter arrangement is designed to maintain stable contact in mixed and broken rock conditions. | 05 / 06 Multiple Size OptionsAvailable in multiple diameters from approximately 115 mm to 250 mm. | 06 / 06 Custom ConnectionsConnections can be customized according to 76, 89 and other drill rod systems. |
Used across blasting, anchor and broken formation drilling
This four-wing spiral PDC drag bit is suitable for blasting holes, anchor drilling, slope support, foundation pit drilling, grouting projects, water well drilling, geothermal drilling, engineering construction and general non-coring drilling.
01 Blasting Hole DrillingStable drilling for blasting holes in broken and mixed formations. | 02 Anchor DrillingReliable hole formation for anchor and slope support drilling. |
03 Slope SupportStable guidance for slope support and foundation pit drilling. | 04 Water Well DrillingEfficient penetration for water well projects in mixed formations. |
05 Geothermal DrillingStable drilling performance for geothermal borehole and energy projects. | |
Suitable Rock FormationsDesigned for mixed, fractured and medium-hard formations. Selected granite-bearing or fractured formations depending on cutter configuration and drilling conditions.
⚠️ Note: Suitable for selected granite-bearing or fractured formations depending on cutter configuration and drilling conditions. Actual drilling performance depends on rock hardness, abrasiveness, fractures, drilling parameters and operating conditions. | ||||||||
Large 1613 cutters as primary cutting elements
This drill bit uses 1613 PDC cutters as the primary cutting elements. Cutter quantity increases with bit diameter to maintain cutting coverage and drilling stability.
1613 Cutters Strong Rock-Cutting CapabilityThe larger cutter structure provides strong rock-cutting capability and efficient penetration in mixed and broken formations. | Wear Resistance Good Wear Resistance1613 PDC cutters provide good wear resistance and stable cutting performance in mixed formations. |
Cutter Quantity Scales with Bit DiameterCutter quantity increases with bit diameter to maintain cutting coverage and drilling stability. | |
