Chip:
1. Please check the round hole diameter is suitable before tapping and take protective measures.
2. When hot water, you need to add water or coolant to prevent overheating and reduce hot water loss. Tapping is required to pause if it is difficult to rotate.
3. Be sure to choose the appropriate cutting oil for complex tapping processing, and apply rust resistant oil for post-use maintenance.
