Product Description
Milwaukee 2 in. Pre-Stressed Concrete Wet Diamond Core Bit
Model Number: 48-17-1020
The Milwaukee 48-17-1020 is a 2 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 wet core bits experience accelerated segment wear from the extreme hardness of high-strength pre-stressed concrete. Pre-stressed concrete's high compressive strength and the potential for contact with embedded high-tensile prestressing tendons create drilling conditions that require a specialized segment bond formulation beyond what standard premium bits provide. Milwaukee engineers the pre-stressed concrete segment bond for maximum performance in these extreme conditions, maintaining cutting effectiveness throughout each hole's depth in materials where standard bonds would glaze rapidly and require frequent reconditioning.
The 2 in. diameter is a heavily used penetration size in commercial construction — covering 1-1/2 in. conduit sleeve installations, major plumbing drain penetrations through elevated pre-stressed slabs, and HVAC connections through parking structure decks. Wet cutting with continuous water supply is essential throughout pre-stressed concrete core drilling — the combination of extreme concrete hardness and the 2 in. cutting face generates significant heat that demands constant water cooling to maintain segment integrity. Milwaukee's pre-stressed concrete bit lineup covers multiple diameters for complete project penetration coverage in pre-stressed structural systems.
For standard cured concrete, Milwaukee's Diamond Premium Wet Core Bit lineup provides optimal performance — see Milwaukee's complete core bit range for all material specifications.
