Diamond Drill for Jewelry – Best Options for Small Holes
When making pendants, beads, or gemstone settings, using the right diamond drill for jewelry is essential for clean holes and preventing cracks in hard stones like agate, quartz, or sapphire. Diamond drills work by grinding the material with embedded diamond particles, rather than cutting like standard bits, which helps produce smoother holes with less chipping.
Many lapidary tools are designed specifically for very small-diameter holes used in jewelry making and gemstone work, with sizes ranging from fractions of a millimeter to several millimeters depending on the application.
A good reference on different drill types and specifications for lapidary and jewelry work is here:

Quick tips for jewelry drilling:
Use water or coolant to reduce heat and extend drill life
Apply light pressure and moderate RPM
Drill slowly to avoid cracking brittle stones
Curious what sizes and drill types other jewelry makers prefer when drilling gemstones for pendants or beads.
