Frequently Asked Questions

What materials are your drill bits made from?

Our drill bits are primarily made from high-speed steel (HSS), with titanium nitride (TiN) or black oxide coatings for enhanced durability and heat resistance. Masonry bits feature tungsten carbide tips.

Can I use your metal drill bits on stainless steel?

Yes, our HSS twist drills are suitable for drilling stainless steel. We recommend using cutting fluid and maintaining a consistent, moderate speed to prevent overheating.

Do you offer custom drill bit sizes?

Yes, we support OEM and ODM services. Contact us with your specifications for custom tool manufacturing.

What is the difference between a step drill and a regular twist drill?

A step drill allows multiple hole diameters with a single bit and is ideal for thin sheet metal. A twist drill is designed for a specific diameter and is better for deeper holes in solid materials.

How should I maintain my drill bits?

Keep bits clean and dry after use. Avoid excessive heat by using proper speed and lubrication. Store in a dry, organized case to prevent damage.
