With the Bahco 3834-EXT-1 extension, you easily expand your hole saw reach with a total length of 330 mm. It is the practical solution when drilling deep holes for pipes or cables through beams, floors, and partition walls without needing to drill from both sides. This extension fits Bahco arbors 3834-ARBR-1130, 3834-ARBR-11152, and 3834-ARBR-11152QC. Thanks to the rigid 7/16" (11.1 mm) hex shank, it prevents slipping in the drill chuck and ensures stable torque transfer for controlled, accurate cutting in deep cavities.
