Sherline 1072 – 1/4 in Drill Chuck with two Arbors
Sherline’s drill chucks are available in 5/32″, 1/4″, and 3/8″ sizes. Runout is .003″ or less. If runout of less than this amount is required, collets should be used to hole the drill rather than a chuck.
A drill chuck is probably the most important accessory you will need for your lathe. It will enable you to accurately centerline drill, ream, or tap any part mounted on the lathe. The part to be machined is chuck or collet mounted in the headstock. The tool is mounted in the tailstock chuck and fed into the part using the tailstock ram feed. Parts that are going to be mounted between centers can be center drilled this way. Other parts requiring a hole accurately drilled on center can also be machined this way.
The Sherline tailstock chuck P/N 1072 is a precision 1/32″ (.8mm) to 1/4″ (6.4mm) 3-jaw chuck complete with key. The chuck is fitted with a #0 Morse arbor for use in the tailstock. Also included is a #1 Morse arbor and drawbolt so the chuck can be used in the lathe or mill headstock as well.
