Bosch 2 608 685 861 bor spiralbor 1 stk.

The Bosch 2 608 685 861 spiral cutting drill bit with SDS max shank is designed for drilling in concrete and masonry. It features a 4-cutter head and a 2-flute U-shaped flute that together provide reliable cutting performance, efficient dust removal and extended tool life. The bit is made with a durable carbide tip and is compatible with rotary hammers that accept SDS max holders.

Advantages

The 4-cutter head reduces the risk of jamming when encountering rebar and helps maintain steady drilling. The 2-flute U-shaped design improves chip evacuation and reduces overheating, which extends service life. A highly wear-resistant carbide composition increases durability and maintains cutting performance during long runs in concrete and masonry.

How to use

Insert the drill bit into the rotary hammer’s SDS max holder according to the tool manufacturer’s instructions until it locks. Start drilling at low speed to establish the hole and then increase to the recommended operating speed for concrete. Apply steady axial pressure without forcing the bit; allow the carbide tip and cutter geometry to do the work. Withdraw occasionally to clear debris if drilling deep holes.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) and, when possible, use dust extraction or wet drilling methods to reduce airborne dust. Match drilling speeds and percussion settings to the rotary hammer and material for optimal life and performance.
