I mentioned earlier of the versatility of the Multifix. It has 40 indexable positions through a 360° circle. Therefore each position is equal to 9 degrees.
Here, I needed to cut off a 1"OD hardened shaft. I didn't want all the mess with a cutoff wheel, and a hacksaw won't touch it. So onto the lathe and used a carbide cutoff tool. Easy peasy. But now to chamfer the end. I could have used a file; I could have attached a 45° chamfer tool, but I'd have to remove a tool from a tool holder and set the height; but since the cutoff tool is still attached, rotate it to the 5th position (5 x 9°=45°), and plunge cut. You can't do that with the Aloris type QCTP without loosening the bolt, rotate it to a measured 45°, and then reset to 90° after you chamfer.
