Milwaukee 1/8" Tile and Natural Stone Drill Bit 48-20-8990
AGGRESSIVE NATURAL STONE PENETRATION
Engineering a bit that survives the high-impact environment of a hammer drill while maintaining precision in brittle materials like glass and ceramic requires superior metallurgy. The Milwaukee 48-20-8990 is designed with a specialized 8-grind carbide head that balances rapid material removal with finished-edge integrity. By reinforcing the carbide tip, Milwaukee has solved the common failure point where standard bits shatter during hammer-mode engagement in dense granite or marble, offering a significant boost to your jobsite consumable ROI.
- / 8-GRIND CARBIDE HEAD: Delivers up to 20% faster drilling speeds in natural stone compared to standard masonry bits.
- / HAMMER MODE READY: Reinforced tip architecture allows for dual-mode versatility, maximizing speed in granite and limestone without fracturing the carbide.
- / 3-FLAT SHANK: Engineered to eliminate bit slippage within the chuck, ensuring maximum torque transfer and protecting the tool's gripping surfaces.
- / EXTENDED SERVICE LIFE: Provides up to 2x life in high-density materials including ceramic, slate, and glass.
