Broca para martillo Bosch Expert SDS Clean max-8X, 22 mm de diámetro, 400 mm de longitud

The Bosch Expert SDS Clean max-8X hammer drill bit with a 22 mm diameter and 400 mm total length is designed for drilling deep, precise holes in concrete and masonry with SDS-compatible rotary hammers. Its geometry promotes efficient dust and debris removal during drilling, enabling steady progress when creating long-reach holes for anchors, through-fixing, and installation tasks. The shank fits standard SDS systems, offering reliable coupling and power transmission for both professional tradespeople and advanced DIY users.

Advantages

The drill bit construction balances cutting efficiency and durability to maintain performance when penetrating dense materials. A flute design optimized for debris evacuation reduces clogging and helps sustain drilling speed over the full 400 mm length. The hardened tip and shaft increase resistance to wear and preserve hole accuracy over repeated use. The SDS-compatible shank ensures stable torque transfer and quick bit changes in rotary hammers.

Suitable for

• Drilling deep anchor holes in concrete and solid masonry
• Through-holes for rebar sleeves, conduits, and fastening systems
• Installation of structural anchors, dowels and mechanical fasteners
• Professional construction and renovation tasks requiring long-reach drilling
• Advanced DIY projects involving concrete or block work

Key specifications

• Type: SDS-compatible hammer drill bit for rotary hammers
• Diameter: 22 mm
• Total length: 400 mm
• Material and tip: hardened cutting tip with reinforced shaft for masonry
• Flute design: optimized for efficient dust and debris evacuation
• Compatibility: for SDS chucks on rotary hammers (SDS system)

How to use

Install the Bosch Expert SDS Clean max-8X bit into the SDS chuck of a compatible rotary hammer until it locks. Select appropriate hammer mode and drilling speed according to the rotary hammer manufacturer’s recommendations and the hardness of the material. Begin drilling with steady pressure, allowing the flute design to evacuate debris; periodically withdraw the bit slightly if drilling deep holes to clear accumulated dust. Use correct personal protective equipment including eye protection and a dust mask or dust extraction when required.

Recommendations

For best results in reinforced concrete or very hard masonry, use controlled, continuous drilling pressure and consider intermittent withdrawal to clear debris. Pair the bit with a tool that provides sufficient impact energy for the 22 mm diameter to avoid excessive heat and wear. Employ dust extraction or vacuum attachment when working indoors to maintain visibility and reduce airborne dust.
