The Bosch HCFC2012B25 Bulldog™ Xtreme SDS-plus® Rotary Hammer Drill Bit (3/16″ x 6″ x 8-1/2″, 25-Pack) is built for precise, durable concrete drilling—especially when rebar is in the mix. Its four-cutter full-head carbide design delivers up to 4X longer life in concrete with rebar (vs. Hawera® SDS-plus® 2-cutter concrete drill bits). The four cutting edges help the bit power through rebar and reduce the chance of getting stuck, while the full-head carbide tip improves strength and helps reduce breakage on rebar strikes.
For accuracy, a centering tip supports precise anchoring-hole placement, and an integrated wear mark shows when the bit is fully worn. The variable 4-2-2 flute design pulls dust away aggressively to reduce heat buildup and help drill more holes per battery charge (compared to a standard four-flute design). Made with Bosch-made carbide for added durability, this bit is designed for SDS-plus® rotary hammers.
