Description
The Starrett 649 Series Spindle Square offers accuracy, convenience and significant time saving with the common shop task of tramming the head of a vertical milling machine. This must be done regularly to ensure squarness and perpendicularity between the spindle and work surface. The spindle square is easier to use and more precise than the traditional method of tramming with a dial test indicator. .0005" Grad, 0-25-0 Dial; .125" Range.
