Pack 5" Automatic Spring Loaded Center Punch, Adjustable Tension, with 2 Replacement Tips

Easy one-handed operation without a hammer. Mark a dimpled starting point in metal (steel, aluminum, brass, copper), wood, glass, leather or plastic surface, preventing drill bits or screws from slipping.

12.7 cm total size, with excellent durability. Composed of a chrome-plated tip and a high-quality stainless steel body, with a non-slip knurled texture giving you a very comfortable and precise operation.

With the tension screw, you can adjust the best tension applied to your work by simply turning the knob. This will allow you to control the striking pressure of the double-spring body and give you the right indentation on the materials you are using.

The package comes with 2 replacement tips with a hardness of 58.

More than a punch, it is also a safety tool in the car. This product is able to work on glass, which means it can break the car window easily to help you escape in an emergency. Besides, the 5 inch dimension is very space-saving in cars.
