I need to cut a couple of 40mm and a 32mm hole in a 9" solid brick wall over the next few weeks, and am weighing up buying tct or diamond core drill bits to drill these rather than renting from HSS or Jewsons's. I have an SDS+ drill with clutch already so the difference in cost is small, and I have the core drill bits to use when I need them, which is usually at the weekend. TCT bits are much cheaper, and seem fine as the bricks are standard soft house bricks, and I only want to cut a small number. Is it worth using diamond cores ?
Thanks
