Bosch Flat Drill Bit Extension

The 150mm Bosch Flat Drill Bit Extension gives your Self-Cut Speed spade bits extra reach when drilling. At 150mm, it is the shorter of the two lengths, adding useful length while keeping the set-up compact and manageable. It has a 1/4-inch hex shank and is intended for use with drill drivers. The impact-rated shank also allows use with impact drivers, so it fits the tools you already have to hand. This extension is ideal for any application with spade bits where a little extra length is needed.
