Its about time (40 years) to tune this thing up
3 inch shorter spindle tube (6 inch long flute capability) (longer tube is still availabile for up to 10 inch flutes)
New air restriction galleys designed so they wont become plugged over time , and easier to produce.
Brass main bushing, interchangeable tubes
Replaceable – you no longer have to buy a complete tool spindle assy if the bushing wears over time -uh
