Product Description
Milwaukee 3 in. Dry Core Masonry Bit
Model Number: 48-17-0030
The Milwaukee 48-17-0030 is a 3 in. Dry Core Masonry Bit — a mid-size dry-cut core bit for cutting through concrete masonry units, cinder block, concrete brick, and standard concrete for conduit sleeve installations and mechanical equipment connections where the 3 in. bore provides clearance for 2-1/2 in. conduit systems and large mechanical fittings, without requiring water for the cutting operation. Milwaukee Dry Core Bits use premium diamonds in a dry-cut specific segment bond formulated for the thermal management and abrasion resistance needed for sustained dry operation without water cooling. The 3 in. diameter generates more heat at the cutting interface than smaller dry core sizes — requiring careful drilling technique, consistent vacuum extraction throughout, and periodic bit cooling breaks to manage segment temperature and maintain segment integrity in sustained dry operation at this larger bore.
Dry cutting at the 3 in. diameter eliminates the water supply logistics, rundown, and wet slurry cleanup that wet cutting would require — important in occupied buildings where water management near active spaces, finished surfaces, and electrical systems is challenging or impractical. OSHA crystalline silica compliance during dry core drilling at 3 in. requires robust vacuum extraction at the source — the 3 in. bore generates substantially more concrete dust than smaller dry core sizes, and adequate extraction airflow must be maintained throughout the operation. Milwaukee's dry core range covers 1 in. through 6 in. for complete dry masonry core drilling coverage across all standard penetration sizes.
For applications where water can be managed, Milwaukee's Diamond Premium Wet Core Bit lineup provides maximum cutting speed and segment life at this diameter.
