Easy to Use It can be used with manual equipment or special processing consoles, such as tapping machines, drill-in-one bench drills, CNC lathes, machining centers, etc. Control the speed according to the hardness of the material. The higher the hardness of the processed product, the slower the speed. Recommended feed rate: General steel: 6-15m/min; harder steel: 5-10m/min; cast iron: 8-10m/min. Tips 1. Before tapping confirm whether the diameter of the round hole is appropriate, and to take protective measures when working. 2. When tapping, it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss. If it encounters difficulty in rotation, the tapping should be suspended. 3. Be sure to select the appropriate cutting oil for the complex tapping process and apply anti-rust oil for maintenance after use.
