2PCS 1/2 inch Square Drive to 1/4 inch Hex Female Socket Adapter Converter Chuck Adaptor for Air and Electric Impact Wrench Impact Drill Ratchet Wrench,Quick Release

For the price its a decent product. It has a good fit of 1/2″ drive for an impact wrench. If used with the wrong 1/4″ hex bit accessory the accessory will likely break well before this will. If a bit gets stuck and won’t release tap the end of the bit and it loosened up for me. Will not hold 1/4″ short stubby bits far enough without them being engulfed by this tool. Not the end of the world like it might be if a short stubby bit was accidently used in a 1/4″ impact driver as they can be tapped out through the middle of the hole down the middle of this accessory. I didn’t try to use the o-rings and pins as I use this as an adapter as needed. Works well to hold longer 1/4″ hex bits and accessories with the ring around the middle.
