The Hammer Drill Bit Robert Bosch Power Tools SDS-plus-7X Expert 10.0×1000 mm 4-cutter is a long SDS-plus masonry bit engineered for drilling deep holes in concrete and other hard substrates. Its 4-cutter head geometry and extended length enable stable, efficient drilling with improved debris evacuation. The bit is designed for use with SDS-plus rotary hammers and is intended for professional construction and renovation tasks where straight, deep anchoring or through-holes are required.

Advantages

The 4-cutter head provides enhanced drilling stability and reduced wandering, resulting in straighter holes. Optimised flute geometry improves dust and debris removal for faster penetration and consistent progress during long-hole drilling. The SDS-plus shank ensures secure tool engagement and quick bit changes in compatible rotary hammers. The extended 1000 mm length allows access to deep drilling positions without the need for extensions or repeated re-drilling.

Suitable for (tasks / use cases)

• Drilling deep anchor holes in reinforced concrete and solid masonry
• Through-holes for services and conduits in walls and floors
• Renovation work requiring long-reach holes without extensions
• Professional construction sites where precision and durability are required

Key specifications

• Shank type: SDS-plus compatible
• Diameter: 10.0 mm
• Total length: 1000 mm
• Tip geometry: 4-cutter head for improved centring and stability
• Intended materials: concrete, reinforced concrete, solid masonry

How to use

Fit the SDS-plus shank securely into a compatible rotary hammer according to the tool manufacturer's instructions. Use the hammer drilling mode when penetrating concrete or masonry. Start drilling with moderate pressure to establish the hole, then maintain steady axial force while allowing the hammer action to do the work. Withdraw the bit periodically to remove accumulated dust and debris, especially when drilling deep holes, to maintain cutting efficiency and prevent overheating.

Recommendations

For extended drilling sessions in reinforced concrete, use appropriate personal protective equipment including safety glasses, hearing protection and a dust extraction system where possible. Match drill diameter and length to the required anchor or conduit size and choose a rotary hammer with sufficient impact energy and power for long, deep holes.
