Broca Bosch SDS plus-7X 18×550×600 mm, SDS-plus, para martillos perforadores

Bosch SDS plus-7X 18×550×600 mm is a long-reach drill bit engineered for SDS-plus rotary hammers to drill deep holes in masonry and concrete. The bit combines a robust flute geometry with a carbide tip to maintain drilling speed and hole quality over extended depths. Its SDS-plus shank ensures secure engagement with compatible chucks and effective transfer of percussion energy, making it suitable for repetitive drilling tasks where consistent performance and shaft stability are required.

Advantages

The drill bit offers extended length for deep-hole applications while preserving straightness and bit life through hardened shaft construction and optimized flute design. The carbide tip provides enhanced wear resistance and fracture toughness when penetrating reinforced concrete and aggregate. The SDS-plus shank design enables quick bit changes and reliable retention during heavy-impact operation, reducing downtime and improving workflow efficiency.

Suitable for

• Drilling long, deep holes in concrete and masonry
• Anchoring and fastening installations requiring deep embedment
• Through-holes for pipes, conduits, and cable routing
• Construction and renovation work involving repetitive drilling

Key specifications

• Shank type: SDS-plus compatible
• Tip material: carbide cutting tip for masonry and concrete
• Overall length: 600 mm
• Working length (effective drilling length): 550 mm
• Diameter: 18 mm
• Flute design: spiral flute for efficient dust removal
• Intended tool type: rotary hammers with SDS-plus chuck

How to use

Select an SDS-plus rotary hammer with appropriate power and operating mode for masonry or concrete drilling. Secure the bit in the hammer’s SDS-plus chuck until it locks into place. Mark the drilling position, start at low rotation to position the tip, then apply steady axial pressure and operate the hammer in impact mode to advance the bit. Withdraw periodically to clear dust from the hole and maintain drilling speed; use water only if recommended for the specific substrate and tool. After drilling, release the bit by retracting the SDS-plus collar and inspect the bit tip and shaft for wear before reuse.

Recommendations

Use appropriate personal protective equipment (eye protection, hearing protection, dust mask) and, when drilling deep holes, consider using a dust extraction system or stop-and-clear technique to remove debris. For drilling near steel reinforcement, reduce feed pressure and moderate rotation to avoid tip damage. Store the bit in a dry place and inspect the carbide tip before use to ensure optimal performance and longer service life.
