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). Rotating the knurled ring closes all three jaws simultaneously to quickly grip round or hexagonal stock. Tommy bars (provided) are used in the holes in the side to tighten and loosen the chuck for more leverage. The chuck has a 3/4-16 thread to fit Sherline’s spindle.
- For those who have jobs where speed and ease of use are more important than maximum accuracy and want a chuck that is loose right from the start (No extra charge).
Add the note “loose jaws” to the comments box above
- Soft (not hardened or machined) steel jaws are also available when you build your own chuck.
Always wear safety glasses when operating machine tools.
