Hammer drill bit Bosch 2608836646 SDS+ for rotary hammer, diameter 22 mm, 1 pc

Hammer drill bit Bosch 2608836646 SDS+ is a single 22 mm masonry bit designed for use with SDS+ rotary hammers. Engineered for hammer drilling into concrete and reinforced concrete, it features a four-cutter tungsten carbide head and four flutes to channel dust away from the impact zone. The 600 mm length provides reach for installation and renovation tasks where durable, long-life drilling is required.

Advantages

The four-cutter head with embedded high-quality tungsten carbide resists jamming and breakage when contacting rebar, while the four-flute design improves dust removal for sustained cutting performance. Compatibility with SDS+ rotary hammers makes the bit easy to mount and use across a wide range of professional tools.

Suitable for

• Drilling holes in concrete and reinforced concrete
• Construction and renovation work
• Electrical, plumbing and HVAC installations requiring through-holes or anchor points
• Professional and occasional users with SDS+ rotary hammers

How to use

Mount the bit into an SDS+ rotary hammer according to the tool manufacturer’s instructions. Use the hammer drilling mode and apply steady forward pressure without forcing the bit; allow the tool and cutter to do the work. Retract periodically to clear dust and prevent overheating. When encountering rebar, reduce feed pressure slightly and let the carbide cutters grind through; if progress stalls, back out and clean the hole before continuing.

What to consider before purchase

• Ensure your rotary hammer accepts SDS+ bits
• Confirm required hole diameter and length (22 mm × 600 mm) match your application
• Check that intended materials are concrete or masonry rather than wood or metal

Recommendations

Use appropriate personal protective equipment (eye protection, dust mask, hearing protection) and, where possible, employ dust extraction or wet drilling measures. For best results, match drilling speed and feed pressure to the material and allow the tungsten carbide head to do the cutting.
