Product Description
Milwaukee 2-1/2 in. Pre-Stressed Concrete Wet Diamond Core Bit
Model Number: 48-17-1025
The Milwaukee 48-17-1025 is a 2-1/2 in. Pre-Stressed Concrete Wet Diamond Core Bit — the maximum segment performance specification for core drilling through pre-stressed and post-tensioned concrete in parking structures, bridges, elevated slabs, and other high-strength structural concrete systems where standard and premium wet core bits experience accelerated segment wear from the extreme hardness of pre-stressed concrete materials. Pre-stressed concrete uses high-strength concrete mixes with compressive strengths substantially above standard structural concrete, and the high-tensile prestressing tendons embedded within the structure create an extremely demanding drilling environment for diamond core bit segments. Milwaukee engineers the pre-stressed concrete bit with a specialized segment bond formulation developed for maximum segment performance in these extreme conditions, maintaining cutting effectiveness at concrete hardness levels where standard segment bonds glaze over rapidly.
The 2-1/2 in. diameter serves conduit sleeve installations requiring 2 in. conduit clearance, major plumbing penetrations, and mechanical system connections through pre-stressed elevated concrete sections in commercial and parking structure construction. Wet cutting with continuous water supply is essential throughout — the combination of extreme concrete hardness and the 2-1/2 in. cutting face generates cutting interface heat that requires continuous cooling to maintain segment integrity during drilling. Available in multiple diameters for the full range of penetration sizes required in structural pre-stressed applications.
For standard cured concrete where the pre-stressed specification is not required, Milwaukee's Diamond Premium Wet Core Bit lineup provides maximum performance at better value — see Milwaukee's complete core bit range for all specifications and sizes.
