Feature (Product Specifications)
The 152mm enhanced four-wing arc PDC drill bit combines 1613 series PDC cutters (16mm diameter) , targeting applications where 152mm (approximately 6 inches) is the standard borehole size. Four blades carry 18 face PDC cutters (4-5 per blade, staggered) plus 4 gauge PDC cutters.
Customized Gauge Protection: The standard type does not have gauge setting. Customers can customize carbide alloy pads or alloy section.
Benefit (Customer Benefits)
For mining operations using 152mm as their standard borehole diameter, the enhanced arc bit provides the body durability needed for hard rock without switching to a larger bit that would require different drilling equipment or casing sizes. The practical benefit is bit longevity that matches the formation demands without changing the drilling program specifications. In hard rock mining at 55-75 MPa, the enhanced bit runs 550-800m between changes versus 250-400m for standard bits, cutting the number of bit changes per 1,000m borehole from 3-4 to 1-2. For a mine drilling 5,000m per month, this saves 10-15 bit changes, equivalent to 40-60 hours of rig time. The 152mm diameter also suits water well construction in hard rock areas where standard water well bits lack the impact resistance for the encountered formations.
Evidence (Field Proven Results)
A gold mining company in South Africa drilling 152mm exploration boreholes in metamorphic rock (quartzite and schist, 50-70 MPa) tested the SUNGOOD TECH 152mm enhanced arc bit alongside their existing standard four-blade arc bits. Over 5 months and 8,000m of drilling: the enhanced bit averaged 640m per run versus 310m for the standard bit, a 106% improvement. All standard bit retirements were due to body cracking; the enhanced bits showed no cracking at retirement, with gauge wear as the limiting factor. Non-productive time from bit changes decreased by an estimated 48 hours over the 5-month period. For operations requiring the larger 170mm diameter for bigger boreholes or raise boring pilot holes, the Factory 170mm Enhanced Four wings Arc PDC Bits 1610 PDC Cutters provides the 170mm enhanced four-wing arc PDC bit with the same 8% cobalt body specification and 1610 cutters.
