3/8″ Drill Chuck with Two Arbors
This chuck includes a #0 Morse arbor for use in the tailstock for center drilling and a #1 Morse arbor for use in the headstock. It will hold drills from 3/32" (2.4 mm) to 3/8" (9.5 mm) in diameter. Runout is .003" or less. If runout of less than this amount is required, collets should be used to hold the drill rather than a chuck.
NOTE: Because of its longer length and ability to hold longer 3/8" drills, this chuck is normally recommended for use on the longer 4400-series benchtop lathes.
