@stephenphelps , Stephen, your driver uses standard 1/4" Hex shank driver bit's, individual or bit kits can be found at any hardware or power tool shop, some times even at the dollar store. Posted a couple links you can order from. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
