Feature (Product Specifications)
The 177mm five-blade arc PDC drill bit is the largest diameter arc-profile bit in the SUNGOOD TECH mining bit range, equipped with 1613 series PDC cutters (16mm diameter).
Five blades carry 20 main PDC cutters (4 per blade) plus 5 gauge PDC cutters.
Nozzle configuration: 4 nozzles at 10-12mm orifice.
The 1613 cutter series provides the largest diamond table area per cutter at 16mm, with 2.2mm diamond layer thickness and HRA >80 hardness.
Advantage (Performance Advantages)
The 177mm diameter combined with the concave profile and 16mm cutters creates the highest single-revolution cutting coverage in the SUNGOOD TECH mining bit lineup.
The 1613 cutters provide 60% more diamond table area per cutter than 13mm cutters, extending individual cutter life by 40-50% in abrasive formations. The five-blade layout maintains hole straightness within 0.8 degrees per 50m in medium-hard rock.
Benefit (Product Value)
For mining operations drilling large-diameter exploration boreholes or pilot holes for raise boring, the 177mm arc bit delivers longer bit life and straighter holes than smaller or flat-profile alternatives. The practical benefit is reduced bit consumption and fewer directional corrections. In a typical mining program drilling 500m of 177mm borehole per month, the 177mm arc bit with 1610 cutters averages 600-900m per bit, requiring only 1 bit change per program. Flat-profile bits at this diameter typically last 350-500m, requiring 1-2 additional bit changes. Each change costs 4-6 hours of rig time plus handling labor. The straighter hole trajectory also reduces the risk of borehole deviation that would require expensive correction drilling.
For operations requiring smaller diameter bits with arc-profile performance, the Factory 115mm Four Wing Arc PDC Drill Bit PDC Bits for Mining Fast Delivery provides a 115mm four-wing arc PDC bit with fast delivery for time-sensitive mining projects.
