Bosch 3/16" x 4" x 6-1/2" SDS-Plus Carbide Rotary Hammer Drill Bit

Bosch 3/16" x 4" x 6-1/2" SDS-Plus Carbide Rotary Hammer Drill Bit is engineered to deliver exceptional durability and performance in concrete drilling applications. Featuring a 100% full-carbide tip design combined with proprietary diffusion-bonding technology, this rotary hammer bit offers four times the life when drilling through concrete with rebar compared to standard SDS-plus bits. The high-heat, high-pressure solid-state welding creates an incredibly strong bond that stands up to tough conditions. This bit also provides 25% more holes per charge thanks to its upgraded variable flute design, which transitions from four flutes to two for efficient dust removal. Its centric conical tip ensures rounder holes for precise anchoring, while a wear mark aids in maintaining drilling accuracy, making it a reliable choice for professional and DIY users alike.
