ATOPLEE Metric Machine Thread Tap, 7pcs HSS Right Hand Extended Straight Flute Tap M3-M12 (All of Sizes)

Note: 1. Straight flute taps are used for through hole and shallow blind hole tapping, not for blind hole tapping.br> 2.Before tapping, confirm whether the diameter of the round hole is appropriate. If the hole is too small for tapping, the tap will wear out more unnecessary, which will increase the risk of tap breakage.br> 3. Control the speed according to the hardness of the material. The higher the hardness of the processed product, the slower the speed.br> 4. When tapping, it is necessary to add water or coolant to cool down to prevent excessive temperature and reduce tap loss. br> 5. When the tap is working, if it encounters difficulty in rotation, the tapping should be suspended. Check the hole diameter and material again, and increase the cooling to reduce the risk of tap damage. br> 6. Please be sure to take protective measures when working, and you need to wear goggles and protective gloves.br>
