Mia F. ★★★★★

Finally got my router to accept some larger bits I've had sitting around—this little adapter fits snug and doesn't wobble at all during use. The threading was clean, so it screwed on without any binding.

Lucy Z. ★★★★★

This adapter threaded on smoothly to my trim router where plastic ones would always bind up. Machining is precise and the fit feels solid.

Lucy N. ★★★★★

Finally swapped out a cheap plastic adapter for this one and the steel threading feels way more secure. The 1/4 inch shank locks in perfectly on my router and the 5/16 thread side holds the bit steady with zero wobble.
