Hammer drill bit Bosch Expert SDS Clean plus-8X 20 mm x 400 mm

Bosch Expert SDS Clean plus-8X 20 mm x 400 mm is a hammer drill bit designed for SDS rotary hammers, offering a 20 mm diameter and a 400 mm working length for drilling in concrete and masonry. The bit combines an SDS shank for secure tool engagement with a flute geometry that improves dust and debris evacuation, supporting stable, deep-hole drilling in construction and renovation tasks. It is intended for users who need reliable performance when making through-holes or deep anchor drillings in solid substrates.

Advantages

The Bosch Expert SDS Clean plus-8X delivers consistent drilling performance with a balanced mix of impact resistance and cutting efficiency. Its flute design promotes effective removal of dust and debris, reducing clogging and enabling faster advance during continuous drilling. The SDS shank ensures quick, secure insertion and reduced play in the chuck, contributing to improved accuracy and longer tool life under professional workloads.

Suitable for

• Drilling through concrete and reinforced concrete for anchors and through-holes
• Creating deep holes in masonry, blockwork, and brick
• Renovation and construction tasks requiring extended working length
• Use with SDS rotary hammers for professional and advanced DIY projects

Key specifications

• Diameter: 20 mm
• Working length: 400 mm
• Shank type: SDS (suitable for SDS rotary hammers)
• Intended materials: concrete, reinforced concrete, masonry, brick
• Flute design: optimized for debris evacuation and stable drilling

How to use

Fit the bit into the rotary hammer’s SDS chuck until it locks securely. Select hammer drilling mode and apply steady axial pressure while allowing the tool to work; avoid excessive force that can accelerate wear. Periodically withdraw the bit during long, deep holes to clear accumulated dust and ensure continuous debris removal. Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask when drilling in concrete or masonry.

Usage recommendations

For best results, match the Bosch Expert SDS Clean plus-8X with a rotary hammer rated for the required impact energy and compatible with SDS shanks. When drilling reinforced concrete, proceed slowly near rebar to avoid sudden deflection; consider using a core or rebar-cutting accessory if repeated metal contact occurs. Store the bit in a dry place and inspect the tip for wear before prolonged use to maintain drilling accuracy and lifespan.
