EGYPTians worked granite (6-7 Mohs) using abrasives, sand & water. An 1883 EGYPTological study by A. Lucas and Flinders Petrie proved copper tube drills could drill through red granite using abrasives. Old Kingdom reliefs show weighted hand drills.

Key facts:

- Predynastic EGYPTian stone vessels dating to 4000-3100 BC show clear rotary drill marks and lathe marks

- Hard stones like granite (6-7 Mohs hardness) were worked using abrasives with quartz, sand and water

- EGYPTians used lapis lazuli, carnelian (hardness 6.5-7), and garnet (6.5-7.5) in jewelry by 4000 BC

- Penn Museum records indicate granite was drilled using jewelled tubular drills with emery cutting points set in the tube

- Pre-dynastic Nakada culture created stone mace heads, cosmetic palettes, and ivory carvings
