Bosch Flat Drill Bit Extension

The 300mm Bosch Flat Drill Bit Extension gives your Self-Cut Speed spade bits maximum reach when drilling. At 300mm, it is the longer of the two lengths, making it the better choice when you need to extend your spade bit further. 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 works with the tools you already have on site. This extension is ideal for any application with spade bits where extra length is needed.
