Really people, please ignore the previous reviews for this product, I just bought this item recently and I can say one thing, it does the job and does it well. As for the bit that takes effort to pull out, boo hoo, its not that hard, yes you can't grip it with bare hands, its meant to stay in and not come out easily, but honestly pliers make it a joke and those who say they had trouble even then getting it out must have no upper body strength, hell i can get it out with rubber gloves. If you buy this product do not remove the ring inside, you will find yourself with ruined bits much faster if not secured in the way it was designed.
