Product Description
Milwaukee 4-1/2 in. Diamond Premium Wet Core Bit
Model Number: 48-17-3045
The Milwaukee 48-17-3045 is a 4-1/2 in. Diamond Premium Wet Core Bit — a large-diameter core bit in Milwaukee's premium wet core bit lineup for major conduit bundle penetrations, large HVAC sleeve installations, and structural access openings through cured and reinforced concrete where the 4-1/2 in. bore provides the clearance needed for the large conduit or ductwork systems being installed. Milwaukee Diamond Premium Wet Core Bits use only premium-grade diamonds in an engineered segment bond that resists glazing and progressive slowing in hard aggregate commercial concrete — maintaining consistent cutting speed across the full project scope of holes in demanding concrete conditions where standard bits lose cutting efficiency progressively. At 4-1/2 in. diameter, the large cutting face generates substantial heat during drilling, making the premium segment bond's glazing resistance and consistent diamond exposure especially important for maintaining effective cutting throughout each deep penetration.
Wet cutting with abundant, continuous water supply is critical at the 4-1/2 in. diameter — water cools the large diamond segment cutting face, flushes the substantial concrete slurry volume, maintains cutting clearance, lubricates the segment-concrete interface, and provides OSHA crystalline silica dust suppression. Core barrel extensions are available separately for penetrations deeper than the standard barrel length provides. Milwaukee's premium core bit range covers 3/4 in. through 12 in. for standardized quality performance across all core diameters on a project.
See Milwaukee's complete Diamond Premium Wet Core Bit lineup for all available sizes and for pre-stressed concrete specifications where additional durability is required.
