Specification and Details
The spindle speed is not stable - this is a known problem with this particular kind of mill. May need attention to the speed control pot, or a replacement controller at some time.
Tooling
There is a 6mm solid carbide end mill. Other suitable tools may be found in the Bridgeport Mill area.
Safety
Do not, ever, use an ordinary Jacobs-type drill chuck to hold milling tools. There is a set of 3 collet chucks with a (home-made) drawbar which is a much more secure and safe way of holding such tools (a drill-chuck is fine when the operating force is along the axis, but will loosen dangerously if sideways forces are applied).
