Drill and re-drill stones, glass, or other hard materials with precision using this 1.4 mm Maillefer diamond drill bit.
Its diamond-tipped end allows for the gradual abrasion of materials that are difficult to work with using a standard drill bit. With a diameter of 1.4 mm, it offers a good balance for creating or reworking a small hole intended for a ring, a rod, or a sufficiently thin wire. It can also be used for finishing work or localized engraving. Diamond drill bits are particularly useful on gemstones, as well as on glass, ceramics, and porcelain.
Note: When using a diamond drill bit to drill a stone, the stone must be kept submerged in water at all times to prevent it from overheating during drilling. Be careful when drilling: only the diamond drill bit should come into contact with the water. The Dremel tool must not touch the water.
What can you do with a 1.4 mm drill bit in jewelry making?
You can prepare a natural stone to turn it into a pendant, drill a hole in a decorative piece to add an eyelet, or enlarge a hole that’s slightly too narrow for your setting. Before you begin, carefully mark the location, then follow the steps in our guide on how to drill a gemstone. The drill bit attaches to a compatible rotary tool, such as a Dremel multi-tool with accessories. When working on a stone, water helps cool the area and the drill bit; the power tool itself must remain out of the water.
Beginner designers should focus on learning not to press too hard. Drilling gradually and taking several breaks generally yields a cleaner result than working too quickly. More experienced designers can use this diameter to precisely adjust their settings and create custom attachment points.
