These adapters are not exact and not accurate. I have used this with a CNC router and the run out on bits with this adapter is 100x greater than bits without an adapter. A drill with a diameter of 3 mm freely enters a hole drilled with a drill with a diameter of 2 mm. That's absurd. The adapter conforms to the product images and fits 1/8" bit to 1/4" collet. That's why I'm not giving 1 star. If you don't need precision or accuracy, but just need rough placement, they will do.
