This 1/4-1/2 drive adapter set is of exceptional quality, fit and strength. Works seamlessly with my new drill driver. Perfect way to turn your power drill into a power socket wrench.

Machining is solid with with nice smooth edges and nice smooth corners. Works like a champ. Material seems to be well made and sturdy.

They come with a nice organizer to keep them together. The packaging is designed to well to keep all the pieces together. I like the rubber holder and the plastic box they come in.

The ball bearing is damaged and too proud of the surface to release properly. Looking in detail at the driver it appears the ball is damaged.
