Frequently Asked Questions

  • Q: What drill bit set should I buy for drilling gemstones?
    A: For gemstone and bead drilling, start with a bead & jewelry set (0.5–3mm electroplated solid bits). For general lapidary work including stone pendants and larger holes, a general lapidary set (1–6mm) provides the best versatility.
  • Q: Are drill bit sets good value compared to buying individual bits?
    A: Yes — sets typically offer 30–50% savings over individual bit pricing and provide a complete size range for most applications. They are ideal for beginners and for workshops that need multiple sizes on hand.
  • Q: Do all bits in a set require water cooling?
    A: Yes — all diamond drill bits require water cooling regardless of size. Water prevents overheating, extends bit life, and produces cleaner holes in stone, glass, and ceramic.
