Frequently Asked Questions

  • Q: What diamond bur should I use to carve designs into rocks and gemstones with a Dremel?
    A: Use flat end cylinder burs for flat-bottomed recesses and channel carving, needle burs for fine line engraving, round ball burs for rounded recesses and organic curved shapes, and tapered inverted cone burs for V-shaped grooves. Always use wet — apply water continuously to cool the bur and stone during carving.
  • Q: What is the best diamond bur for engraving lettering and designs on glass?
    A: Use fine needle burs (1.3mm–1.8mm) for line work and lettering, flat end cylinder burs for shading and surface texture, and ball burs for stippling and dot patterns. Work at 10,000–15,000 RPM with light pressure and keep the glass wet.
  • Q: What RPM speed should I use for diamond carving burs on stone and glass?
    A: Use 5,000–10,000 RPM for hard stones like agate, jasper, and jade. Use 10,000–15,000 RPM for softer stones and glass engraving. Always use water cooling regardless of speed.
