Ask the Experts Drill Holes Q&A

What are the names of the types of drill holes for jewelry? 

The most frequently used drill hole types for beads and pendants are:

• Top Drill: The hole starts near the top edge of the bead or pendant and goes at an angle (not centered). Often used for briolette beads, teardrops and leaf shapes.
• Center Drill: The hole goes straight through the center of the bead, typically side to side. This is the most common drill type for round beads.
• Side Drill: The hole is drilled near the edge of a flat or irregular piece, side to side. This is often found in coin beads or discs. It creates a pendant-like drop when strung.
• Front Drill: The hole goes from front to back. This is often used on flat-backed stones or pendants. It is common in cabochon settings and vertical-style pendants.
