Bosch SDS-plus® Bulldog™ Xtreme Rotary Hammer Drill Bit 5/8 in. x 10 in. x 12 in.

Crafted for professionals who demand speed, precision and long life, the Bosch SDS-Plus Hammer Bit delivers outstanding performance in concrete and masonry. Its Bosch-made carbide tip and proprietary brazing/hardening process provide exceptional wear resistance and drilling efficiency. A 4-flute design evacuates dust quickly, keeping the bit cooler and extending service intervals, while the centric tip ensures fast, accurate starts. A built-in wear mark alerts you when the bit has reached its service limit—so you can maintain ANSI-compliant performance on every job.

Whether you’re setting anchors, running conduit or drilling through block and brick, this SDS-Plus bit provides consistent, punch-through results every time.
