Birzman nipple drives with free rotation.

This tool is incredibly practical for the wheel builder.

It makes it easy and quick to screw nipple and spoke together.

The bit head has a small pin that makes sure to center the screw head on the nipple.

The rotating head ensures that you do not have to turn the tool, but simply move it around in a small circle.

Can be used with rims up to 45mm high.
