Bosch Bulldog Hc2040 Sds-plus Hammer Drill Bit, 1/4 X 4 In.

The Bosch Bulldog HC2040 is an SDS-Plus carbide-tipped hammer drill bit designed for fast, efficient drilling in concrete, stone, brick and masonry. Its 1/4-inch diameter and 4-inch overall length deliver the reach and control needed for medium-size holes on demanding job sites. The carbide tip and optimized 4-flute geometry work together to reduce friction, speed debris evacuation and produce cleaner holes with less resistance, helping you complete projects faster while extending tool life.

Whether you are a professional contractor or a serious DIYer, this bit's engineered design minimizes interruptions and reduces wear on your rotary hammer. The SDS-Plus shank provides quick-change compatibility with all standard rotary hammers, letting you swap tools efficiently between tasks. A wear mark alerts you when the tip wears beyond ANSI specification, so you can replace the bit before performance declines.
