Available41 products
Rotary toolholder retention knobs thread into the shank of a tapered toolholder to provide a pull stud for a milling machine's drawbar to grab. They allow the toolholder to be properly seated and held into the spindle bore. These knobs are used to replace stripped or deformed retention knobs before they cause damage to the toolholder or spindle bore. They fit specific spindle tapers and sizes.
