Hamerboor Bosch 2 608 836 644 — diameter 22 mm, voor boorhamers, 1 stuk

Bosch hammer drill bit 2 608 836 644 is a single 22 mm diameter bit designed for use with rotary hammers. It is intended for impact drilling in masonry and concrete and is compatible with SDS Plus chucks. The bit is supplied as one piece and is suitable for tasks in construction, renovation and installation work that require impact drilling in hard substrates.

Advantages

The 22 mm masonry bit provides a robust cutting head designed for repeated impact drilling. A multi-cutter head geometry and flute design help remove dust from the hole during drilling, reducing clogging and maintaining drilling progress. Constructed with a wear-resistant carbide cutting tip suited for masonry and concrete, the bit is built for extended use in demanding drilling applications. The SDS Plus shank ensures secure retention in compatible rotary hammers and straightforward insertion and removal.

Suitable for

• Drilling holes in concrete and masonry
• Anchoring and fixing work for construction and renovation
• Installation tasks for electricians, plumbers and HVAC technicians requiring impact drilling

Key specifications

• Diameter: 22 mm
• Compatibility: SDS Plus rotary hammers
• Intended use: Impact drilling in masonry and concrete
• Quantity: 1 piece
• Typical application length: suitable for through-holes and standard anchor depths (check tool and anchor requirements)

How to use

Select a rotary hammer with an SDS Plus chuck and ensure the tool is set to the hammer drilling mode. Insert the 22 mm Bosch bit firmly into the chuck until it locks. Mark the drilling position, use an appropriate pilot or centre punch if needed, and start drilling at low speed to establish the hole before increasing speed and applying steady pressure. Periodically withdraw the bit to clear dust and inspect the hole. Use appropriate anchors or fixings sized for a 22 mm hole once drilling is complete.

Recommendations

Always use eye, ear and respiratory protection and follow the rotary hammer manufacturer's safety instructions. Match drill depth and anchor type to the substrate and intended load. For reinforced concrete, monitor progress and reduce feed pressure if hitting rebar; use purpose-made rebar bits or cutting procedures if prolonged contact with reinforcement occurs.
