Shipping Details

The Bosch Bulldog™ Tough Rotary Hammer Bit features a four-cutter head, for an SDS-plus® with fast drilling and enhanced durability in concrete with rebar. This bit delivers 2X life vs. standard SDS-plus® bits. These bits feature a four-cutter design, helping to prevent the bit from getting stuck in rebar, one cutting edge that hits the rebar no matter the angle, so it doesn’t get stuck and break. The four-flute design aggressively pulls dust away from the work, for fast drilling and longer bit life. This bit provides accurate centering, making it ideal for anchoring.

What Customers Are Saying

Customers overwhelmingly praise this masonry drill bit for exceptional performance drilling through concrete, brick, and block with remarkable ease and speed. Most report drilling dozens of holes—some 36 to 40—through thick slabs up to 14 inches deep without issue. Reviewers highlight the centering tip for accurate hole starting and note the bit's durability through extended use and demanding projects. Many emphasize it outperformed previous bits and exceeded expectations. A small number report premature dulling on reinforced concrete or rebar, though these concerns represent minimal feedback. Overall, customers express strong approval and willingness to repurchase.
