Product Description
Milwaukee 7/8 in. Diamond Premium Wet Core Bit
Model Number: 48-17-3009
The Milwaukee 48-17-3009 is a 7/8 in. Diamond Premium Wet Core Bit for precision core drilling through cured and reinforced concrete in commercial and industrial construction. 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 aggregate commercial concrete. The 7/8 in. diameter serves specific conduit sleeve, anchor bolt, and mechanical penetration applications where the bore must be sized precisely to this specification rather than the adjacent 3/4 in. or 1 in. standard sizes — specific sleeve hardware, conduit systems, and structural fastening systems call out 7/8 in. bore where the adjacent sizes would either not fit the hardware or provide more clearance than needed for the structural application.
Wet cutting with continuous water flow is essential for diamond core bit performance — water cools diamond segments against cutting interface heat, flushes concrete slurry from the hole to maintain cutting clearance, lubricates the cutting interface, and suppresses crystalline silica dust for OSHA compliance. Milwaukee's premium core bit range covers 3/4 in. through 12 in. in the same premium segment specification, allowing contractors to standardize on consistent quality performance across all core diameters needed on a project. The 7/8 in. core bit is used across Milwaukee's full range of core drilling platforms including SDS+, SDS Max, and dedicated diamond core drill machines for applications where the production pace or structural requirements justify different platform choices.
