This is the 5C spindle headstock. The spindle is heat treated and the angle is ground off of the bearings to ensure that the spindle runs within .0002. Includes the collet draw bar, pulley, spindle lock tool and spindle tighten tool (Weight 13 pounds)
The dovetail is the standard size used on all Taig machines, however, it is not recomended to apply this spindle to the standard or CNC Taig Micro-Mill (Too large and heavy!)
Lathe operation with pullies supplied is between 300 rpm - 2000 rpm.
