Rotary Hammer Drill Bit Bosch Expert SDS Clean max-8X 24 mm x 400 mm

Bosch Expert SDS Clean max-8X 24 mm x 400 mm is a rotary hammer drill bit engineered for SDS-compatible rotary hammers. With a 24 mm diameter and 400 mm overall length, the bit is intended for through and deep-hole drilling in concrete and masonry. The SDS shank ensures a secure connection to compatible tools and supports efficient transfer of impact energy for faster penetration and consistent hole quality.

Advantages

The drill bit delivers precise, clean holes in reinforced and unreinforced concrete thanks to a carbide tip geometry designed for masonry applications. Its long 400 mm length enables deep drilling without extensions, while the SDS system provides fast bit changes and stable retention during heavy use. The engineered flute design evacuates dust and debris effectively to maintain drilling speed and reduce friction.

Suitable for

• Drilling through concrete walls and slabs
• Creating deep anchor or fastening holes for construction fixings
• Installing pipes or conduits through masonry
• Professional and DIY projects requiring accurate, repeatable holes

Key specifications

• Diameter: 24 mm
• Overall length: 400 mm
• Shank type: SDS-compatible
• Intended materials: concrete, masonry
• Tip: carbide for improved wear resistance and cutting performance
• Flute design: for efficient dust evacuation

How to use

Install the bit into an SDS-compatible rotary hammer until it locks in place, following the tool manufacturer's instructions. Select an appropriate drilling mode (rotary hammer or hammer drilling) and start at low speed to position the hole, then increase to the recommended speed and apply steady axial pressure without forcing the bit. Periodically withdraw the bit to clear dust and cool the tip when drilling deep holes. Wear appropriate eye, ear and respiratory protection when drilling.

Usage recommendations

For optimal results, use the bit with a rotary hammer that matches SDS compatibility and recommended power for 24 mm drilling. Regularly clear dust from the hole and let the bit cool during extended drilling sessions to extend tool life. Replace the bit when wear affects hole accuracy or cutting performance.
