Product Description
Milwaukee 6 in. Dry Core Masonry Bit
Model Number: 48-17-0060
The Milwaukee 48-17-0060 is a 6 in. Dry Core Masonry Bit — the largest standard size in Milwaukee's dry core drilling lineup, designed for large-diameter dry cutting through concrete masonry units, cinder block, concrete brick, and standard-strength concrete where water supply is unavailable, where water damage to adjacent materials prohibits wet cutting, or where OSHA crystalline silica compliance is best managed through dry cutting with vacuum extraction. At 6 in. diameter, this bit is used for the largest penetrations in masonry wall construction — major HVAC ductwork penetrations, large conduit bundle sleeves requiring 5 in. or 6 in. clear bore, structural access openings, and specialty penetrations where the full 6 in. diameter is specified by the mechanical, electrical, or architectural drawing requirements. Milwaukee's dry core bit diamond segment specification uses a bond formulation engineered for sustained cutting performance in dry operation, where the segment bond chemistry must provide heat resistance and self-cooling properties to manage cutting interface temperature without water cooling assistance.
At 6 in. diameter, the surface area of the cutting face is substantially larger than smaller core bits, generating more total heat during drilling and making the dry-cut segment specification even more critical for maintaining segment integrity throughout the drilling operation. Vacuum extraction is essential at this diameter for two reasons: OSHA crystalline silica exposure compliance requires dust capture at the point of generation, and accumulated concrete dust at the cutting face of a 6 in. dry core bit contributes significantly to segment overheating by insulating the segments from any ambient air cooling. Milwaukee's dry core bit lineup covers 1 in. through 6 in. in the same dry-cut diamond segment specification, providing a complete system for dry masonry core drilling across all penetration size requirements from small conduit holes through the largest ductwork openings.
For applications where wet cutting is feasible, Milwaukee's Diamond Premium Wet Core Bit lineup provides maximum cutting speed and segment life with water cooling for the most demanding concrete core drilling work.
