Bosch 3/8" x 10" x 12" SDS-Plus Xtreme Carbide Rotary Hammer Drill Bit is engineered to deliver exceptional durability and performance in demanding concrete drilling tasks. Featuring a full-carbide tip and proprietary diffusion-bonding technology, this rotary hammer bit four times the lifespan when drilling into concrete with rebar d to standard SDS-plus bits. The advanced diffusion bonding process uses high heat and pressure to create a solid-state weld that ensures an incredibly strong bond for long-lasting use. Designed for efficiency, the bit’s upgraded variable flute design transitions from four flutes to two, enabling faster dust removal and allowing you to drill 25% more holes per battery charge. Its centric conical tip produces rounder holes for precise anchoring, while a wear mark helps maintain accuracy throughout your projects. Model Number:
