Our Spindle Taps include a spindle bushing at no additional cost!
We have decided to include a spindle bushing. This adds value in that there is no need to provide a counterbore when tapping you mandrel. You don't need to have or purchase another larger Forster drill bit. It is sometimes difficult to get the counterbore and tap drill size perfectly concentric. It is a good idea to always use a spindle bushing.
