Product Description
Milwaukee 4 in. Diamond Premium Wet Core Bit
Model Number: 48-17-2040
The Milwaukee 48-17-2040 is a 4 in. Diamond Premium Wet Core Bit — a large-diameter core bit in Milwaukee's premium wet core bit lineup for major conduit bundle sleeves, large mechanical equipment penetrations, and structural access openings through cured and reinforced concrete where the 4 in. bore provides the clearance for the fittings, equipment connections, or conduit systems being installed. Milwaukee Diamond Premium Wet Core Bits use only premium-grade diamonds in an engineered segment bond that resists the glazing and slowing that standard bits experience in hard aggregate commercial concrete — the premium segment specification maintains consistent cutting speed and segment integrity across the full project scope of holes in demanding concrete conditions. At 4 in. diameter, the large cutting face generates significant heat, making the premium segment bond's glazing resistance particularly important for maintaining cutting speed throughout each hole's depth.
Wet cutting with abundant, continuous water supply is critical at the 4 in. diameter — water cools the diamond segments against the substantial cutting interface heat, flushes the large volume of concrete slurry from the hole interior, maintains cutting clearance, lubricates the segment-concrete interface, and provides OSHA crystalline silica dust suppression on occupied commercial jobsites. Core barrel extensions are available separately for penetrations deeper than the standard barrel provides. Milwaukee's premium core bit range covers 3/4 in. through 12 in. in the same premium segment specification 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 segment durability is required.
