    Does anyone know what size masonary drill bits I would need to use to fit M6 and M8 faithfull shield anchor bolts in a wall?

    I tried using a 10mm for the M6's but they seemed tight in hole and didn't want to belt it in in case it got stuck halfway and couldn't get it out!

    Any help/suggestions appreciated

    M6 usually a 12mm and M8 usually a 14mm and you'll be needing SDS bits. Should give a drill size on the bolt case.

    Also back em off a bit before you put them in so that the flanges are flat.
