Diamond Reaming Burs

These conical diamond-coated burs are designed for reaming and refining the holes in glass beads, making them an essential tool for lampworkers, bead makers, and glass artists. The tapered profile allows you to gradually enlarge and smooth bead holes with precision, helping achieve a clean finish while reducing the risk of chipping or cracking.

The diamond-coated working section provides excellent cutting performance on glass and other hard materials, while the conical shape makes it easy to access narrow openings and create a smooth, even taper where required.

Ideal for cleaning up bead holes after kiln annealing, removing sharp edges, or adjusting hole sizes to fit cords, findings, and jewellery components.

Manufactured with a durable steel shank and a diamond-coated working surface for long-lasting performance.

A practical and versatile addition to any lampworking or glass studio.
