Bosch HC5043 SDS-Max Speed-X 7/8 In. x 31 In. x 36 In. Rotary Hammer Drill Bit

The Bosch HC5043 is a 7/8 in. diameter SDS-Max Speed-X rotary hammer drill bit designed for fast, precise drilling in concrete and masonry. With a 31-inch working length and 36-inch overall length, this bit handles deep-hole applications with ease, making it ideal for professional contractors and heavy-duty jobsite use.

Engineered with a solid carbide head and robust S-cutter design, this bit stays sharper longer and delivers more on-spec holes than competitive alternatives. The inclined side cutters maximize drilling speed, while angled dust channels reduce heat buildup to extend bit life. A long-pitch spiral flute increases material removal speed and reduces vibration during operation.

• Solid carbide tip stays sharper longer for extended bit life and more holes within specification
• Inclined side cutters provide the highest drilling speed in concrete and masonry
• Active-centering tip enables quick, accurate starts for precision drilling
• Wear mark indicator confirms hole diameter accuracy throughout the bit's service life
• Compact head design promotes fast dust removal and improved cooling
• Long-pitch spiral increases drilling speed and reduces vibration
