Drill Chuck with drawbar prevents the taper spinning in the lathe so preventing damage to your precious morse taper fittings. The drillchuck comes with a Multistar Marlin morse taper arbor which takes a (detachable) threaded rod and conical shape nut. The threaded rod goes right through the lathe spindle and is secured by the nut so the chuck cannot slip out of the taper. As it is held in securely it is unlikely to slip round and score the surfaces. Also the chuck being secure can be used to grip small wooden objects for turning giving you a miniature woodturning chuck. Chuck plus key plus nut plus 200mm of threaded rod supplied for you to cut down to a suitable length.
Drillchuck takes 2mm up to 13mm or 1/2" drill shanks.
Not suitable for lathes with no through-hole in the spindle.
Useful in the tailstock too unless your tailstock is the type with the barrel telescoping onto another threaded barrel. i.e. if the tailstock barrel effectively changes length as you operate it the drawbar will not work.
The drillchuck will unscrew from the Marlin arbor allowing you to fit the range of Marlin heads also available. If you want to fit a drive centre head then the adjustable centre point will also need to be purchased.
