Ultra short form tapping head gets its first trials on mill and lathe.

[Mook]

My challenge was to make a tapping head as short as possible for smaller machines. I decided to fit all the working parts inside the arbor that is inside the spindle. This first prototype is an R8 taper with an adapter to suit a 32mm bore lathe tooolholder. Using the quick release system also allows for other machining operations by locking the spring loaded collet holder.This design allows tapping on the lathe carriage and also on mills with a worm drive quill. A MT3 model is almost finished for use in a lathe tailstock or mills with a morse taper spindle.
