Product Description
Milwaukee 3 in. Diamond Premium Wet Core Bit
Model Number: 48-17-2030
The Milwaukee 48-17-2030 is a 3 in. Diamond Premium Wet Core Bit for precision core drilling through cured and reinforced concrete in commercial and industrial construction applications. Milwaukee Diamond Premium Wet Core Bits use only premium-grade diamonds in an engineered segment bond formulated for faster cutting speed and longer segment life than standard-grade core bits in demanding concrete drilling conditions. The 3 in. diameter serves major utility and mechanical penetrations including 2-1/2 in. conduit sleeve installations, large plumbing drain penetrations, HVAC refrigeration piping, and fire sprinkler branch line penetrations where the 3 in. bore provides the clearance required for the conduit or pipe system's outer dimensions plus fittings and sleeve hardware. At this larger diameter, the premium segment specification's advantage over standard bits is more pronounced — the greater cutting face area and heat generation at 3 in. make segment quality a more significant determinant of drilling speed and life than at smaller diameters.
Wet cutting with continuous water flow is essential for diamond core bit performance at this diameter — water cools the diamond segments against the cutting interface heat that would cause rapid glazing without cooling, flushes concrete slurry from the hole to maintain cutting clearance, lubricates the segment-concrete interface, and suppresses crystalline silica dust at the source for OSHA compliance on occupied commercial jobsites. Milwaukee's premium core bit range covers 3/4 in. through 12 in. in the same segment specification for consistent premium performance across all core diameters needed on a project. The 3 in. core bit is used in Milwaukee's full range of core drilling platforms from SDS+ and SDS Max rotary hammer setups through dedicated diamond core drill machines.
