Each cutter head is manufactured in strict accordance with precise data. Second, the material depends on whether it has enough hardness without losing toughness, good impact resistance, and good corrosion resistance.

If you have a peculiar smell after receiving the product, it is recommended that you wipe it clean before use. Third, the handle conforms to the human body design and is more comfortable to hold.

Because the screwdriver has higher hardness and stronger brittleness , excessive force is easy to cause the screwdriver to break , especially for the screwdriver below 1.5mm , please do not screw hard , and select the appropriate size corresponding to the normal operation .
