Note：

1. Please note that this is a left-hand tap.

2. Straight groove taps are used for through hole and shallow blind hole tapping, not for blind hole tapping.

3. Before tapping, it is confirmed whether the diameter of the round hole is appropriate. If the tap is tapped with a hole that is too small, the tap will be more unnecessary wear, which will increase the risk of tap breaking.

4. The rotation speed is controlled according to the hardness of the material. The higher the hardness of the processed product, the slower the rotation speed.

5. When tapping, it is necessary to add water or coolant to cool down to prevent excessive temperature from reducing the strength of the tap.

6. When the tap is working, if it encounters difficulty in rotation, the tapping should be suspended. Check the aperture and material again, and increase the cooling to reduce the risk of tap damage.

7. Please be sure to take protective measures when working, and you need to wear goggles, protective gloves, etc.
