Petrol drill Blue Bird BB 52: for drilling operations

The petrol drill Blue Bird BB 52 is designed to make drilling operations easier during outdoor work where mains electricity is unavailable. The 53.2 cc Blue Bird two-stroke engine drives the Bosch UBH 12-520 hammer unit, using tools with an SDS-max fitting.

Hammer unit and drilling capacity

The hammer unit combines rotation with the tool’s percussion action. The stated capacity is 52 mm in concrete with a twist drill bit; 55 mm with a special bit; 90 mm in masonry with a face core bit. The bit type and material are part of the drilling specification; this is not a single capacity that applies to every tool.

Tools and fuel

The SDS-max fitting identifies the compatible tool system. Drill bits and core bits are not stated as included. For the two-stroke engine, prepare the fuel using the ratio specified in the manual.

Use and maintenance

Follow the manual for fuel, lubrication and pre-work checks. Clean and maintain the machine with the engine switched off, checking guards and fasteners.
