Hi, I read in a book, that when the pups bite each other, the one bitten yelps, and goes away, so as his owner, you yelp, turn and give him your back, ignore him, you can add a NO as well.
Giving him chew toys is a good practice, something that he will delight in chewing are the tendons sold by merricks called flossies, I cut one in half and my 2 each get one of the halves. This will keep him occupied, content for 30 minutes or so.
I would also distract him to something else, perhaps a walk, a game of catch with a small squeeky tennis ball (sold at petsmart or walmart).
Like some have advised, perhaps if NONE of the above helps, take an empty soda can put some coins in it, this has been known to deter bad behavior perhaps it can help in this case, when he bites say NO and shake the can.
Good luck, if all this fails, talk with a dog trainer, perhaps your vet can advise you to a good one, or even some at petsmart are willing to give a little advise for Free.
