Pro Tip: Keep Your Bits Lubricated

Frequently Asked Questions
Q: What materials can these diamond coated drill bits cut through?
A: These diamond coated drill bits are designed for hard, brittle materials such as glass, jade, gemstones, ceramics, porcelain tiles, shells, and jewelry components. The industrial-grade diamond coating provides the hardness needed to drill cleanly through these materials without cracking or chipping.
Q: Do I need to use water or lubricant when using these drill bits?
A: Yes — it is highly recommended to keep the drill bit lubricated with cool water throughout the drilling process. Water lubrication dissipates heat, prevents premature wear of the diamond coating, and protects your workpiece from thermal damage or breakage.
Q: What rotary tools are compatible with the 2.35mm shank?
A: The 2.35mm shank is a standard size that fits most popular rotary tools, including Dremel-style tools, flex shaft machines, and mini drills. Always check your tool's chuck capacity before use to ensure compatibility.
Q: How many bits are included and what sizes are in the set?
A: The set includes 10 pieces total, covering sizes 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, and 2.5mm — giving you a comprehensive range for precision drilling, grinding, and polishing tasks.
