These adapters work perfectly. I use a used Harbor Freight plunge mill, and now my large collection of 1/4" shank bits shouldn't be limited to use in my smaller, mostly underpowered, mills. general. The small lip on one end perfectly prevents the adapter from slipping into the collet. My only issue is that once the adapter is in place it's tight enough that it can be quite difficult to pull it back out of the collet, but it's not. Expect something processed to those tolerances.
