Warm TIPS:

1. Thin drill bits are more prone to breaking than thick ones. Ensure the drill bit is perfectly straight when drilling. Avoid applying excessive force as it can damage the drill bit.

2. Apply cutting oil before drilling. It eases the process, prevents breakage, and keeps the drill bit from overheating.

3. Begin drilling slowly and gradually increase the speed. High speed at the start can cause the drill to slip.
