The mystery of bore holes in ancient Egypt

Abusin is located 50 km from the Giza Egyptian pyramid. This place previously had 3 Pyramids, they were built during the 5th Dynasty in Egyptian history, ie after the Pharaon Khufu era about 4100 years ago. In Abusin, it was discovered on harder lava cliffs than granite that drilled very round holes.

The mystery of round drill holes in ancient Egypt

From the very beginning, the Neolithic period , humans knew how to use stone pestles to create holes in marble. Like that, people also create holes in the bones or lava cliffs.

The boreholes in Abusin are not ordinary boreholes, but bore holes . It is a kind of difficult drilling technique, and when drilling is completed the center forms a groove in the center of a spiral-shaped rock mass. When conducting drilling, can not arbitrarily like how to hold the drill, but holding it to adjust somehow can drill into the center of the stone. The drilling block and tool must be in a certain position. In order to have a straight drill line, workers need to have coordinated equipment. If only relying on manual drilling techniques, it is not possible to have straight and regular drill holes. Looking at the drill hole, one could tell the direction of the drill, but it was obvious that they did not use the diamond drill to drill.

And the hole is also not used to chisel a series of holes, then use the grinding method to process. On the borehole, there is still a whirlpool, a cut of the drill.

What does this discovery mean?

Someone raised an objection, they said that the bore of mind is created by modern people. If so, just drilling a hole is enough, why do all the blocks in Abusin have drill holes? Moreover, very early, 1000 years ago, the Fde Lins Pater described the extremely enlightened bore holes of this 5th Dynasty . Therefore, the idea that these boreholes created by modern people is uncertain.

Equipped by ancient Egyptian architects , we have not known anything so far. This radial drilling technique is not a random invention. Technical progress is an orderly progressive process. To conduct drilling holes, the invention of the drill is not enough, but there must be other appropriate tools. like diamond drill. And to be able to use diamond drills and drillers, workers must also have appropriate materials. So far this question is still open and people can only come to admire the statues and bores with a question without explanation.
