Hammer drill Bosch EXPERT 2608900255 — 32 mm diameter, 400 mm length

Bosch EXPERT 2608900255 — 32 mm diameter, 400 mm length hammer drill is designed for drilling deep, precise holes in masonry, concrete and similar hard building materials. The long 400 mm shaft allows access to recessed or hard-to-reach points while the 32 mm cutting diameter provides a stable bore for anchors, sleeves and through-holes. The bit is intended for use with compatible chucks and holders and is suitable for both professional tradespeople and experienced DIY users who require reliable performance for long-reach drilling tasks.

Advantages

The drill combines a long working length with a large diameter to enable deep, accurate holes without repeatedly repositioning the tool. Its geometry is optimized for efficient material removal in masonry and concrete, reducing plugging and heat build-up during extended drilling. Robust construction ensures dimensional stability and consistent cutting performance under heavy loads, while compatibility with standard holders and chucks simplifies installation and replacement.

Suitable for

• Drilling deep anchor and fixing holes in concrete and solid masonry
• Creating through-holes for pipes or conduit where extended reach is required
• Construction and renovation tasks requiring reliable long-reach drilling
• Professional trade work and advanced DIY projects involving hard materials

Key specifications

• Cutting diameter: 32 mm
• Overall working length: 400 mm
• Suitable materials: concrete, solid masonry and similar hard substrates
• Design: long-reach hammer drill geometry for efficient dust and debris removal
• Compatibility: designed for use with appropriate chucks, holders and hammer drilling systems

How to use

Select a compatible chuck or holder that matches the drill and the hammer drill or rotary hammer being used. Mark the drilling position and ensure the work area is secure. Use appropriate safety equipment including eye protection, hearing protection and a dust mask. Begin drilling at low speed to establish the hole, then increase to the recommended hammering speed for the material. Apply steady axial pressure without forcing the bit; allow the tool and bit to remove material at their designed rate. Periodically withdraw the bit to clear dust and debris for efficient cutting and to reduce heat buildup. After completing the hole, inspect the bore for correct depth and diameter before inserting anchors or fixings.

Recommendations

For best results, use the drill with hammer-capable rotary tools rated for long-reach bits, maintain correct feed pressure, and clear debris frequently. Choose the correct safety gear and use water extraction or dust control systems where required to reduce airborne silica when drilling concrete or masonry.
