Product Description
Milwaukee 5 in. Dry Core Masonry Bit
Model Number: 48-17-0050
The Milwaukee 48-17-0050 is a 5 in. Dry Core Masonry Bit — a large-diameter dry-cut core bit for cutting through concrete masonry units, cinder block, concrete brick, and standard concrete for major conduit sleeve installations and mechanical equipment connections where the 5 in. bore provides clearance for 4 in. conduit systems and large mechanical fittings, and where water supply for wet cutting is unavailable or impractical. Milwaukee Dry Core Bits use premium diamonds in a dry-cut specific segment bond formulated for the thermal management needed for sustained dry operation without water cooling. At 5 in. diameter, the dry-cut segment specification manages the higher heat generation of the larger bore compared to smaller dry core bit sizes — requiring careful drilling technique, vacuum extraction, and periodic bit cooling breaks to maintain segment integrity during extended dry core drilling operations.
Dry cutting at the 5 in. diameter eliminates the water supply logistics, rundown, and slurry cleanup that wet cutting at this large bore would require — an important practical advantage in occupied buildings where water management near active spaces is challenging, in electrical equipment rooms, and in any situation where wet cutting logistics are impractical. OSHA crystalline silica compliance during dry core drilling at this diameter requires robust vacuum extraction — the larger bore generates substantially more concrete dust than smaller diameters, and adequate extraction airflow must be maintained throughout the drilling operation. Milwaukee's dry core range covers 1 in. through 6 in. for complete project dry drilling coverage.
For applications where water can be managed, Milwaukee's Diamond Premium Wet Core Bit lineup provides maximum cutting speed and segment life with water cooling at this large diameter.
