Frequently Asked Questions

Q: What sizes are included in this micro twist drill bit set?

A: This set includes 13 micro drill bits ranging from 0.8mm to 2.0mm in diameter, all featuring a standard 2.35mm shank. The range covers the most common sizes needed for PCB drilling, jewelry making, model crafting, and fine engraving work.

Q: What materials can these HSS micro drill bits cut through?

A: Thanks to their HSS alloy steel construction, these bits are suitable for drilling through a variety of materials including wood, plastic, acrylic, thin soft metals, resin, and PCB circuit boards. The spiral flute design ensures smooth chip removal and clean hole walls across all these materials.

Q: Are these micro drill bits compatible with my rotary or engraving tool?

A: Yes! The 2.35mm shank is a universal standard that fits most rotary tools, mini drills, and engraving handpieces without the need for an additional adapter. Always check your tool's collet specifications before use to confirm compatibility.

Q: How do I get the best results when using micro drill bits?

A: For best results, use a consistent, steady speed and apply light, even downward pressure — never force the bit. Keep the work surface firmly secured, and allow the spiral flutes to naturally clear chips as you drill. Starting with a small center-punch mark helps prevent the bit from wandering on smooth surfaces.
