Product Description
Milwaukee 4-1/4 in. Diamond Wet Core Bit
Model Number: 48-17-2042
The Milwaukee 48-17-2042 is a 4-1/4 in. Diamond Wet Core Bit for drilling clean, precise core holes through cured concrete in applications where the 4-1/4 in. bore diameter is specified for specific conduit systems, sleeve fittings, plumbing components, or mechanical hardware whose outer dimensions require a bore larger than the standard 4 in. but within the 4-1/4 in. specification. Milwaukee Diamond Wet Core Bits are manufactured to the highest quality standards using only premium-grade diamond segments bonded to quality steel barrels for the cutting speed and segment life that professional core drilling demands. The 4-1/4 in. core bit serves the specific applications where mechanical, electrical, or plumbing installation components are dimensioned for this exact bore size — providing the correct clearance for the component's outer diameter while minimizing the hole size to preserve the concrete cross-section's structural integrity as much as possible for the required penetration.
Wet cutting with continuous water flow is essential for diamond core drilling performance — water cools the diamond segments against the heat generated by the cutting interface, flushes concrete slurry from the hole to maintain cutting clearance, lubricates the segment-concrete contact to reduce friction, and provides source-point silica dust suppression for OSHA crystalline silica compliance. At 4-1/4 in. diameter, the cutting face area and generated heat are substantial enough that wet cutting is particularly important for maintaining segment quality and drilling speed throughout the full core. This bit is designed for cured unreinforced and reinforced concrete — for pre-stressed and post-tensioned concrete applications requiring maximum segment life, Milwaukee's pre-stressed concrete core bit lineup provides a specialized segment specification for those extreme-hardness materials.
Milwaukee's wet core bit lineup spans 2 in. through 12 in. for the full range of core drilling diameters — see the complete lineup including premium and pre-stressed concrete specifications for all available sizes.
