Sherline 3.1", 4-Jaw Independent Chucks
Description
- 3.1" diameter 4-Jaw independent chuck for larger work
- Clamping range: 3/32" (2 mm) to 1-1/2" (38 mm) diameter
- Hole through the chuck is .687" (17 mm)
- Hex key included
- Spindle Thread: 3/4-16
The larger Sherline 3.1", 4-Jaw Independent Chucks take maximum advantage of the size available on a standard Sherline lathe. This larger chuck takes up no more center-to-center space than the 2.5" chuck, but it will hold larger work. It has a clamping range of from 3/32" (2 mm) up to 1-1/2" (38 mm) diameter with the jaws in the normal position. With the jaws in the reversed position, work up to 2-3/4" (70 mm) can be gripped.
The hole through the chuck is .687" (17 mm). A hex key (provided) is used to tighten each jaw individually. A groove is machined around the base of the chuck so that angle clamps can be used to mount it to the table of a mill as a holding fixture. The chuck has a 3/4-16 thread to fit Sherline's spindle and other machines using that thread.

I’ve had a Sherline lathe for several years. I never got on with their 3 jaw standard chuck and that put me off using any of their other chucks. Instead I bought both 3 jaw and 4 jaw independent from other suppliers…and they were fine except they were never designed for a small machine like this. So eventually I treated myself to the Sherline 4 jaw 3.1 inch independent. It’s a good chuck. Well and tightly engineered and the holding capacity is more than my other chucks. It’s chunky without being huge, it’s certainly not a toy. As with any 4 jaw independent, once you’re comfortable setting it up it’s great and of course inherently more accurate when replacing stock. So I’m pleased with it, no regrets. One criticism though…the jaws are operated by a fairly small Allen/hex key. It’s a bit awkward and doesn’t feel that it would tighten enough….but it does, it isn’t a problem…I would have just preferred a more substantial probably square key. But I’m definitely happy to have spent the money on it, it’s a good bit of kit
