Sherline 2280 Quick-change 1/4 on Tool Holder
One of these toolholders is included with the P/N 2250
quick-change tool post system. If you are working with several
different 1/4″ tools that you would like to have pre-installed in
interchangeable tool holders, purchasing this part separately
allows you to have additional 1/4″ holders on hand to take full
advantage of the quick-change system.
