Bosch HC4C2012 SDS-Plus Bulldog 3/16" x 6" x 8" Rotary Hammer Drill Bit – 4-Cutter Carbide Tip for Concrete with Rebar

The Bosch HC4C2012 SDS-Plus Bulldog Rotary Hammer Drill Bit delivers fast, precise drilling and exceptional durability for concrete applications—even when hitting rebar. Equipped with a four-cutter carbide-tipped head, this bit lasts up to 2X longer than standard SDS-plus two-cutter bits.

The 4-cutter design ensures at least one cutting edge is always in contact with rebar, preventing the bit from binding or breaking. A centering tip allows for precise hole placement, making it ideal for anchoring work. The four-flute design quickly channels dust away from the hole, improving drilling speed and extending the life of the bit. Crafted from Bosch-engineered carbide, it’s built to withstand heavy-duty jobsite use.
