Since granite is hardness level 6.5 this would require either diamond tipped tools or perhaps iron-carbide rotary saws and such. Some of the inner granite is high in Quartz crystal, likely due to it's piezo-electric effect, which is level 7 hardness. (see: https://www.ianknapper.com/infographic/mohs-stone-hardness-scale-infographic/ )

Could it be that high pressure water tools may have been used? This might explain why there are none left to this day. Here is a video showing water used to cut granite: https://www.youtube.com/watch?v=XuTV6HiPyi8

    $\begingroup$ Hi Tomachi, and welcome to Worldbuilding! Is your question about the real-world historical tools used to build the Giza pyramids? If so, such a question might be a better fit for the History stackexchange. If you're asking about ways to make the Giza pyramids in a fictional world, we'll need to know a bit more about your background and story. $\endgroup$ – Dubukay Nov 11 '18 at 2:13

    $\begingroup$ First, ask on History Stack Exchange. Second, it definitely was no water pressure tools, the technology to support that did not exist. Third, a NOVA recreation of pyramid building methods demonstrated that copper tools could effectively cut granite, as long as you were willing to spend a lot of time re-sharpening tools. $\endgroup$ – kingledion Nov 11 '18 at 4:35
  • $\begingroup$ Granite was used a a construction stone in all times, from the deepest antiquity to our days. The Egyptians even made colossal granite statues of pharaohs, such as Amenhotep III. The Roman-built walls of Lugo (3rd century CE) have towers with bases of dressed granite stones. The Romans most certainly did not have diamond tipped tools or iron-carbide rotary saws. There are people today who are building a castle using purely medival technology, including quarying the stone and dressing it. $\endgroup$ – AlexP Nov 11 '18 at 9:14

Most stone is limestone, which is much easier to cut.
Granite was cracked, or worked with granite hammers
