Frequently Asked Questions

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

A: These high speed steel titanium-coated drill bits are designed for use on wood, aluminum, iron, soft metals, plexiglass, and hard plastics. They are ideal for general DIY, home repair, and light construction/engineering applications.

Q: Are these twist drill bits compatible with an impact drill?

A: No — these bits are designed for use with a needle vice or a low-speed electric drill. They are not suitable for impact drills, as the high torque and hammering action can damage the bits and reduce their lifespan.

Q: Do I need to pre-drill a pilot hole before using these bits?

A: No pre-drilling is needed. The self-starting tip design allows you to begin drilling directly on your workpiece without a pilot hole, saving you time and effort on every project.

Q: How many sizes are included in the 99-piece drill bit set?

A: The set includes 14 distinct size increments ranging from 1.5mm (approx. 1/16") to 10mm (approx. 1/4"), with multiple bits of each size included, giving you a total of 99 individual drill bits.

Q: Are the drill bits rust-resistant?

A: Yes. The titanium coating on each bit provides anti-rust and wear-resistant protection, helping the bits last longer even with repeated use across various materials.
