Ground joint & Thread Holding Tools

Our ground joint holders are top notch! These tools are designed to hold a ground joint. They are hollow so that you can blow air into the glass piece that is being held. We have made the handle out of Stainless Steel for long lasting tool life. The graphite is super high density and made to hold up to harsh working conditions. The sizes we currently offer are 10mm, 14mm, and 18mm Male and Female holding tools. For reference, we named these tools for the glass shape that is being held, not the shape of the graphite on the tool!
