The Hyper-Finish Drive Head fits every size mandrel in the Hyper-Finish Diamond Sizing System. The Mandrel Retaining Nut is the only piece you'll need to remove to change the mandrel. An easy to read and easy to use feed knob makes adjusting the hone simple. Each witness mark on the feed knob equals approximately .001" increase in hone diameter. The drive head has a balanced yoke and body to keep the drive head symmetrical at any speed.
The Drive Head is included in the Master Kit.
