Product Description
Milwaukee 2 in. Dry Core Masonry Bit
Model Number: 48-17-0020
The Milwaukee 48-17-0020 is a 2 in. Dry Core Masonry Bit — a mid-to-large diameter dry-cut core bit for cutting through concrete masonry units, cinder block, concrete brick, and standard concrete for conduit sleeve installations and mechanical penetrations where the 2 in. bore provides clearance for 1-1/2 in. conduit and specific plumbing and mechanical applications. Milwaukee Dry Core Bits use premium diamonds in a dry-cut specific segment bond formulated for the thermal management and self-cooling properties needed for sustained cutting in dry operation without water cooling — an important practical advantage in field masonry drilling situations where water management is impractical or undesirable. The 2 in. diameter is a common conduit sleeve specification in commercial and industrial electrical installations for single large conduit penetrations and in mechanical work for larger plumbing and HVAC piping requiring this bore through masonry walls.
Dry cutting eliminates the water supply, hose management, and wet slurry cleanup that wet core drilling requires — particularly valuable in finished or partially occupied spaces where water rundown on walls below the drilling location would damage finishes, in electrical equipment rooms where water near energized equipment creates safety hazards, and in any situation where the logistics of wet cutting would delay or complicate the work. For OSHA crystalline silica compliance during dry core drilling, vacuum extraction must be used continuously to capture concrete dust at the source — vacuum extraction also removes accumulated dust from the cutting face that contributes to segment glazing in dry operation. Milwaukee's dry core masonry bit range covers 1 in. through 6 in. for complete dry drilling coverage at all standard penetration sizes.
For applications where water can be managed effectively, Milwaukee's Diamond Premium Wet Core Bit lineup provides maximum cutting speed and segment life with water cooling.
