The Dremel 7150 is a two-piece set of diamond-coated rotary bits, the 7103 and the 7144, both on a 1/8-inch shank that fits any Dremel rotary tool. Diamond grit lets them cut, engrave, carve and finish hard materials that ordinary abrasive bits struggle with, including glass, ceramic, hardened steel and semi-precious stone. They are detail bits, not stock-removal tools, so they suit small touch-up and precision work rather than heavy grinding. Owners rate the set well for fine engraving, though some find the bits small for larger jobs and easy to wear when pushed hard.
