Product Description
Milwaukee 3 in. Pre-Stressed Concrete Wet Diamond Core Bit
Model Number: 48-17-1030
The Milwaukee 48-17-1030 is a 3 in. Pre-Stressed Concrete Wet Diamond Core Bit — engineered for drilling through pre-stressed and post-tensioned concrete in parking structures, bridges, and elevated structural decks where standard and premium core bits experience accelerated segment wear from the extreme hardness of high-strength pre-stressed concrete. The 3 in. diameter serves major conduit sleeve installations requiring 2-1/2 in. conduit clearance, large plumbing drain penetrations through elevated pre-stressed slabs, and mechanical system connections through post-tensioned structural floors in commercial and parking structure construction. Milwaukee's specialized pre-stressed concrete segment bond formulation provides the thermal management and abrasion resistance needed in these extreme concrete conditions, maintaining cutting effectiveness where standard premium segment bonds glaze rapidly under the elevated drilling resistance of pre-stressed high-strength concrete.
Wet cutting with continuous water supply is essential throughout pre-stressed concrete drilling — the combination of extreme concrete hardness and the 3 in. cutting face generates significant heat that requires constant cooling to maintain segment integrity. Water simultaneously cools segments, flushes slurry, lubricates the segment-concrete interface, and provides OSHA crystalline silica dust suppression throughout the operation. On large parking structure or bridge projects where many penetrations through pre-stressed sections are required, the pre-stressed bit specification's extended segment life relative to standard premium bits directly reduces bit consumption and drilling downtime across the project scope. Available in multiple diameters for complete pre-stressed concrete penetration coverage.
For standard cured concrete, Milwaukee's Diamond Premium Wet Core Bit lineup provides optimal value — see Milwaukee's complete core bit range for all material specifications and sizes.
