What size bolts are you going to be using? M8s? If so, id go no bigger than 10mm holes. yes you need to leave expansion space but not that much! Also, get your self down B&Q. They have a Makita drill bit and bit set half price at £20. Just picked my self one up on the company card and the drill bits are bloody good quality.
