FAQs

What materials can I use this drill set on?

This drill set is designed for spot weld removal on metal sheets in automotive and metal fabrication applications.

What is the purpose of the titanium coating?

The titanium coating helps prevent the bit from dulling due to overheating, thereby extending the bit's lifespan.

What drill speed should I use?

Start with a lower speed and adjust as needed, depending on the material and the size of the bit.

How do I maintain the drill bits?

Keep the bits clean and dry when not in use. Use cutting fluid or lubricant during drilling to reduce heat and friction.

What safety precautions should I take?

Always wear safety glasses to protect your eyes. Use appropriate gloves and clothing.

Can I use this set on stainless steel?

While the set can work on stainless steel, it's designed primarily for general metal applications. Extra care and cutting fluid are recommended.

What if a drill bit breaks?

Always use the correct drill speed and pressure. If a bit breaks, replace it with a new one.

Troubleshooting

Drill bit is dulling quickly.

Reduce the drill speed and check if enough cutting fluid is being used. Apply even pressure and let the bit do the work. Inspect the bit for damage.

Drill bit is not cutting through the spot weld.

Ensure you are using the correct speed and pressure. Check the sharpness of the bit and replace if necessary. Make sure the bit is centered on the weld.

Drill bit is overheating.

Reduce the drilling speed and ensure that you are using enough cutting fluid to keep the bit cool.
