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.
Dysprosium was discovered in 1886 by French chemist Paul Ãmile Ã©mile lecoq De boisbaudran when he separated dysprosium oxide from holmium. Oxide boisbaudran also discovered gallium in 1875 and isolated samarium for the first time in 1879 using fractional. separationaturally occurring dysprosium is a mixture of seven isotopes and they are found in the percentages shown: 156 Dy (0.06%), 158 Dy (0.1%), 160 Dy (2.3%), 161 Dy (18.9%), 162 Dy (25.5%), 163 Dy (24.9%) and 164 Dy (28.2%). The most abundant isotope is 164 Dy at 28.2%.
