The bit is 1/8 shank, and I bought it at Lowes. I don't think it is made by Dremel, but it works just fine. The cutting flutes do not go to the end of the bit, but stop about 1/8 from the end. Let's make something.
Sulfur was discovered and known since ancient times. However, it was officially recognized as an element around 1777 by Antoine Lavoisier in France. Apparently, the year and person(s) who discovered sulfur     are unknown to science. We do know it was used up to 2000 years before the birth of Christ by pagan â¦ priests.
Oxygen was discovered in 1772 by Carl Wilhelm Scheele, but he did  not publish his discovery until after Joseph Priestly had published  his independent discovery of oxygen i â¦ n 1775. As a result, Priestly  is usually credited with the discovery.oseph Priestly, an English chemist, independently, discovered oxygen in 17 â¦ 74 and published his findings the same year, three years before Scheele published.
