Description

The 7/16 UNC spiral flute tap and drill set delivers reliable threading for applications requiring this intermediate-to-large diameter. Producing a 9.4mm thread diameter with 25mm threading length, this combination tool is well-suited for automotive components, machinery fabrication and structural metalwork where seven-sixteenth inch UNC threads are needed.
