The Bosch Bulldog SDS-Plus S4 rotary hammer bit is built for fast, accurate drilling in concrete, block, brick, and stone. The patent-pending 4-flute carbide tip clears dust quickly, the centric head improves hole roundness, and the SDS-Plus shank locks into any standard rotary hammer.

• SDS-Plus shank fits Bosch Bulldog and all standard SDS-Plus rotary hammers
• Patent-pending S4 carbide-tipped 4-flute design for fast spoil removal
• Centric carbide head improves hole roundness and tracking
• Hardened, tough head resists extreme drilling loads
• For concrete, brick, block, stone, and other masonry
• 1 bit per package
• Diameter: 5/16"
• Overall length: 6"; useful working length approximately 4"

Tip: Use this bit in a rotary hammer's hammer-drill mode for concrete and masonry, not a standard drill. Blow dust from the hole before setting an anchor for full holding strength.
