Bosch 2 608 597 777 broca

The Bosch 2 608 597 777 drill bit is a 260 mm length SDS-plus hammer drill bit engineered for precision drilling in masonry, concrete and reinforced concrete. With a working length of 200 mm and a 6 mm diameter, this bit is suited for making accurate holes while maintaining stability during rotary hammer operation. Its hardened construction and optimized flute geometry promote efficient dust evacuation and reduced wear for consistent drilling performance.

Advantages

This drill bit offers compatibility with all rotary hammers that use an SDS-plus holder, ensuring quick and secure bit changes. The 6 mm diameter and 200 mm working length provide a balance between reach and stiffness, supporting straight drilling and reduced bit wandering. Durable materials and a design focused on chip removal extend service life and maintain drilling speed in demanding materials.

Suitable for

• Drilling anchor and fixing holes in masonry
• Creating through-holes in concrete and reinforced concrete
• Installation of dowels and small anchors in construction and renovation

Key specifications

• Diameter: 6 mm
• Working length: 200 mm
• Total length: 260 mm
• Shank type: SDS-plus compatible
• Recommended application materials: masonry, concrete, reinforced concrete

How to use

Install the bit into the SDS-plus chuck of a rotary hammer according to the tool manufacturer’s instructions. Select hammer drilling mode when working in concrete or reinforced concrete. Mark the drill point, start at low speed to position the bit, then apply steady pressure and allow the tool’s hammer action to do the cutting. Withdraw periodically to clear debris if drilling deep holes and maintain stable, even pressure throughout the operation.

Recommendations

Wear appropriate eye, ear and respiratory protection when hammer drilling. Use correct drill speed and allow periodic withdrawal for dust removal to extend bit life. For reinforced concrete, ensure rebar location before drilling to avoid damaging the bit or the structure.
