Product Description
Milwaukee 3-1/2 in. Pre-Stressed Concrete Wet Diamond Core Bit
Model Number: 48-17-1035
The Milwaukee 48-17-1035 is a 3-1/2 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 decks, and other high-strength structural concrete systems where standard and premium wet core bits experience accelerated segment wear from the extreme hardness and abrasiveness of pre-stressed concrete materials. Pre-stressed concrete uses high-strength concrete mixes with compressive strengths substantially above standard structural concrete specifications, creating drilling conditions where the cutting resistance per unit of drill advance is significantly higher than conventional concrete drilling. The Milwaukee pre-stressed concrete bit uses a specialized segment bond formulation that maintains diamond exposure and cutting effectiveness in these extreme concrete conditions where the segment bond must manage both the higher abrasive wear rate and the impact loading that occurs if the drill approaches embedded high-tensile prestressing tendons.
The 3-1/2 in. diameter serves applications including large conduit sleeve installations requiring 3 in. conduit clearance, major mechanical penetrations through elevated structural concrete decks, and HVAC and utility penetrations through post-tensioned slab and beam systems in commercial and parking structure construction. Wet cutting with continuous water supply is essential throughout the drilling operation — the combination of extreme concrete hardness and larger bore diameter generates substantial cutting interface heat that requires continuous cooling to maintain segment integrity. Milwaukee's pre-stressed concrete bit lineup covers multiple diameters for the full range of penetration sizes required in structural pre-stressed and post-tensioned concrete 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.
