Frequently Asked Questions

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

A: These titanium-plated high-speed steel twist drill bits are suitable for drilling through wood, aluminum, iron, hard plastics, and plexiglass. They are not recommended for masonry or concrete.

Q: Can I use these drill bits with any power drill?

A: These small drill bits (1–3mm) are designed for use with a needle vice or low-speed electric drill. They are not compatible with impact drills, which can snap the fine bits due to excessive torque and vibration.

Q: What is the difference between the 50-piece and 99-piece sets?

A: The 50-piece set is a great starter kit for light DIY and hobby use, while the 99-piece set offers a broader range of sizes and more bits per size — ideal for frequent users or professional applications requiring greater variety.

Q: What does the titanium plating do?

A: The titanium coating on each drill bit significantly reduces friction and heat during drilling, which helps the bits stay sharper longer and improves overall cutting performance compared to uncoated HSS drill bits.
