Product Description
Milwaukee 8 in. Diamond Premium Wet Core Bit
Model Number: 48-17-3080
The Milwaukee 48-17-3080 is an 8 in. Diamond Premium Wet Core Bit for large-diameter core drilling through cured and reinforced concrete in commercial and industrial construction where the 8 in. bore is specified for major mechanical and utility penetrations. Milwaukee Diamond Premium Wet Core Bits use only premium-grade diamonds in an engineered segment bond that maintains optimal diamond exposure throughout the segment's service life, resisting the glazing that causes standard bits to slow progressively in hard concrete. The 8 in. diameter serves major applications including large conduit bundle sleeves requiring 6 in. or larger conduit clearance, major mechanical equipment connections through structural concrete floors, large HVAC ductwork penetrations, and any penetration where the bore must accommodate fittings and hardware with 8 in. outer dimensions. At this large diameter, the premium segment specification's glazing resistance directly translates to more consistent drilling speed and longer bit life than standard bits in demanding commercial concrete conditions.
Wet cutting with abundant continuous water supply is absolutely critical at 8 in. diameter — the heat generated at the cutting interface at this large bore requires aggressive water cooling throughout every drilling cycle to prevent the rapid segment glazing that would end the drilling operation. Water also flushes the substantial concrete slurry volume generated per inch of depth at 8 in. from the hole interior, which is as important as cooling for maintaining productive drilling speed. For 8 in. core drilling in production commercial settings, the premium segment specification ensures consistent cutting speed from first hole to last across a project scope requiring multiple large-bore penetrations. Core barrel extensions are available for sections deeper than the standard barrel depth.
