Frequently Asked Questions

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

A: These titanium-plated HSS drill bits are designed for drilling into wood, plywood, aluminium, iron, mild steel, hard plastics, and plexiglass. The titanium coating reduces friction and heat build-up, making them particularly effective for metalworking and DIY tasks requiring small, precise holes.

Q: Are these drill bits compatible with any standard electric drill?

A: Yes — these small drill bits (1mm–3mm) are compatible with needle vices, pin chucks, and low-speed electric drills. However, they are not recommended for use with impact drills, as the high vibration can damage or break the fine-diameter bits.

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

A: Both sets include the same range of bit sizes (1mm to 3mm and beyond). The 99-piece set simply includes more bits of each size, giving you a larger backup supply — ideal for frequent users, workshops, or those who want a long-lasting stock of the most-used sizes.

Q: Do these bits need pre-drilling before use?

A: No. One of the key advantages of this drill bit set is that the self-starting tip design allows drilling to begin immediately without the need for centre-punching or pre-drilling, saving time and improving accuracy on both hard and soft materials.
