Just bought some new Bosch stand alone cases. all in one case. But the new housings are about 1/4 inch shorter for these bits. The internal dimensions of the new adaptable cases had to be long enough to accommodate the longest of these masonry drills. Or maybe Bosch should have made 5 3/4" instead of 5 7/8" drill bits. Please don't get me wrong, I love the idea of these custom cases. And I love the idea of these modular clips, for both long and short drive bits. When it comes to drills, Bosch is just crazy.
