What This Product Does
The 76mm three-wing arc PDC drill bit drills 76mm boreholes in soft to medium-hard formations for applications that require a small, maneuverable bit with factory-direct pricing. At 76mm, this is one of the smallest PDC drag bits in the SUNGOOD range, making it suitable for portable rotary rigs, underground mine bolting rigs, and shallow hand-augered water wells where larger bits cannot be deployed due to rig size or borehole access constraints. The three-wing arc configuration provides directional stability at small diameter while maintaining competitive factory pricing through standardized production processes.
Key Features & Technical Specifications
Outer diameter: 76mm. Blade count: 3.
PDC cutters: 1308 series, 3-4 cutters per blade (12 cutters) .
Connection: Customer-specified thread
Weight: 4.6 kg.
Recommended flow: 30-80 L/min.
Factory price category: standard production, minimum order 10pcs.
Performance Advantages
In coal measure rock and soft sandstone at 15-50 MPa, the 76mm three-wing arc bit delivers 2.0-4.5 m/min, which is among the fastest penetration rates in the small-diameter class. The lightweight 4.6 kg body reduces rod-string fatigue in handheld and portable drilling applications where the operator physically manages the drill head. The three-wing arc profile maintains borehole deviation below 1.0 degree per 30m even in interbedded formations. At factory-direct pricing, the 76mm bit costs 25-35% less than equivalent bits from international brands while matching or exceeding their bit life in comparable formations.
Application Scenarios
Underground coal mine gas drainage and roof bolting where small-diameter boreholes are standard. Shallow hand-portable water-well drilling in rural communities across Africa and South Asia. Geotechnical probe holes for slope stability monitoring. For surface water wells requiring a larger diameter, the 113mm Super Customized Three Wings PDC ARC Drill Bit provides a 113mm three-wing arc profile with higher flow capacity. Environmental monitoring well installation for groundwater sampling.
Problem-Solving Capabilities
Imported small-diameter PDC bits in the 70-80mm range often carry 3-4 week delivery lead times and premium pricing, which delays drilling programs in remote locations. The 76mm three-wing arc bit ships from the SUNGOOD factory within 7-10 days at standard production pricing, with no minimum order requirement. A mining contractor in Mozambique reported that switching to factory-direct 76mm bits reduced their per-bit procurement cost by 30% and eliminated project delays caused by international supply chain disruptions.
Technical Support & Customization
SUNGOOD TECH offers full customization of the 76mm bit including connection thread type, matrix composition, and cutter layout density. Custom arc angles from 10 to 25 degrees available for specific formation types. Impregnated diamond variants available for hard-rock zones within coal measure sequences. Bulk order pricing available for quantities above 50 pieces.
