Bosch drill bit for concrete SDS+ 12 mm, model B 2608833811

Bosch drill bit for concrete SDS+ 12 mm (model B 2608833811) is a rotary‑percussion drill accessory designed for use with hammer drills that accept SDS+ shanks. It is intended for drilling 12 mm diameter holes in concrete, masonry and similar mineral materials. The bit geometry and carbide tip are engineered to withstand the impacts and high loads of hammer drilling while delivering consistent hole dimensions for anchor installation, cable routing and fixture mounting.

Advantages

The SDS+ 12 mm concrete drill bit combines robust carbide cutting edges with a reinforced flute geometry to remove debris efficiently and reduce binding during drilling. Its SDS+ shank ensures secure tool-to-bit connection for stable drilling and quick bit changes. The bit is manufactured to Bosch production standards for repeatability and compatibility with SDS+ hammer drills from Bosch and other compatible brands.

Suitable for

• Drilling 12 mm holes in reinforced and non-reinforced concrete
• Creating anchor and dowel holes for construction and installation
• Routing cable conduits and pipe entries through masonry
• Renovation and retrofit tasks requiring rotary‑percussion drilling

Key specifications

• Drill diameter: 12 mm
• Shank type: SDS+
• Intended material: concrete, masonry and similar mineral substrates
• Tool type compatibility: hammer drills with SDS+ chuck
• Cutting tip: carbide tip for percussion drilling

How to use

Install the drill bit into the SDS+ chuck of a compatible hammer drill until it locks securely. Select hammer or rotary‑percussion mode on the drill according to manufacturer recommendations for concrete. Start drilling at low speed to seat the bit, then apply steady pressure and maintain a consistent drilling rhythm. Periodically withdraw the bit to clear dust and debris from the hole and prevent overheating. For deeper holes, drill in stages and inspect the bit and tool for wear during extended use.

Recommendations

Use appropriate personal protective equipment such as safety glasses, dust mask and hearing protection when drilling. Choose drill speeds and feed pressure recommended by the drill manufacturer and replace the bit when cutting performance decreases or the carbide tip is damaged. For reinforced concrete, consider using a dedicated rebar‑drilling technique or a bit specified for mixed material applications.
