I don't have the drill parts with me to check, but will update you at the weekend. It was a Makita 6-piece plumbers holesaw kit, but looking online there are some variations between Brazil and other countries, so I cannot say for sure. The 3/4" pipe hole was done with a 25mm part, and I *think* the 1" was done with a 38mm part.
