What does that tell you? The hole in a drill guide are oversized quite a bit, so it's easy to put the bits in and out. Probably if you put a 1/4 inch bolt in the hole for a 1/4 inch drill bit, it would fit in really loose because the hole is larger. If you then used the 1/4 inch bit to drill your holes as you suggest, you wouldn't be able to assemble the parts because of tolerances. You may not even get 1 in since the bit wears down.
