来自埃及的4500年铜工具如今是世界上最古老的已知旋转钻机,揭示了先进的古代冶金和交易。 A 4,500-year-old copper tool from Egypt is now the world’s oldest known rotary drill, revealing advanced ancient metallurgy and trade.

1927年在埃及巴达里挖掘的铜工具被确定为世界上最古老的回转钻,可追溯到第4千年末——比以前已知的例子早2000年。 A copper tool from a 1927 excavation in Badari, Egypt, has been identified as the world’s oldest rotary drill, dating to the late 4th millennium BCE—over 2,000 years earlier than previously known examples. 来自纽卡斯尔大学和维也纳美术学院的研究人员发现了旋转运动的证据,包括细刺和弯曲工作端,表明它被用作弓形钻头。 Researchers from Newcastle University and the Academy of Fine Arts in Vienna found evidence of rotary motion, including fine striations and a curved working end, indicating it was used as a bow drill. 该工具的复杂合金含有砷、镍、铅和银,这表明了先进的冶金和可能的贸易联系。 The tool’s complex alloy, containing arsenic, nickel, lead, and silver, suggests advanced metallurgy and possible trade connections. 该发现刊登在《Naqada IID Date》* 上, 重新定义埃及早期的手工艺, 强调重新审查博物馆收藏的价值。 The discovery, published in *The Earliest Metal Drill of Naqada IID Dating*, redefines early Egyptian craftsmanship and underscores the value of re-examining museum collections.
