---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- 【High Carbon Steel Material】The tap and die are made of alloy steel, high carbon steel, which has high hardness, fatigue resistance, wear resistance and corrosion resistance. The cutting speed of high-alloy HSS tool steel is four times that of normal tool steel. [Screw Hole Thread Repair] Thread taps are suitable for threading carbon steel, cast iron, aluminum, copper, stainless steel, and other metals. Ideal for rethreading fasteners and fastener holes in automotive and equipment repairs. 【Precision Cutting】All cutting teeth are precision CNC machined and precision heat treated to a hardness of 60HRC, ensuring smooth, burr-free cutting for optimal thread cutting performance. 【Easy to use】The tapered design of thick tap and thin tap and die makes making and re-threading internal and external threads smoother and easier. Comes with a box for convenient storage and transportation.
