Would a 1.5″ diamond bit be suitable for drilling in brick and stone?
Sure it would work – and no you don’t need water – but I’ve never used a drill bit that size that doesn’t go on a ‘huge rotary impact drill’. Maybe it’s a difference in living areas, but here in Toronto, Ontario, Canada, any bit that size would be configured with an SDS shaft, which only fits into a rotary impact drill. Why not just rent the package for the 4 Hr min charge. You’ll zip through the wall in less than 10 minutes instead of #@*&ing around for who knows how long – consider what your labour costs per hour. Anyway – good luck.
