I need to buy a reliable and precise pin chuck; i.e, a pin vise that can be inserted into a larger drill press (or in my case, Sherline mill). It needs to securely hold fairly small bits (#76 - #80), and its shank has to be 3/8" or less (although I would prefer 1/8" if possible). Anyone have suggestions where I could buy this?
I have one - probably intended for Dremel - but either I can’t get the bit in there straight or it wobbles.
Try this chuck, I’ve used it on my Sherlines and it works pretty good for a tool under $10. Caution, it is an adjustable Metric tool. Ha Ha! The Amazon listing offers various sizes in black and aluminum finish. Get 2 of them for under $15, one in each finish.
The listing says you can use it with your milling cutters, haven’t tried that yet.
MSC has several types and sets. Of course, they are more expensive than anyone else. here is the link: pin vises
I bought this, and while it holds tiny drills, I can’t figure out how to use it.
The drill chuck has a removable hex shaft on it. The threads on the shaft open and close the jaws. About 3/4" of thread length is required to fully close the jaws. However, my morse taper arbor that attaches to my drawbar only has about 1/4" of thread so it doesn’t even begin to engage the jaws. If I put it into my drill chuck, I don’t have enough Z-height to use it.
Thoughts please?
Parts are inter-changable between all of Sherline’s products. Buy a taller z axis and lead screw. That will give you 3 more inches of clearance at least. That’s what I did on my mill at home.
OK, got it. Thanks.
As an interim hack, you could make a couple different length spacers, slightly smaller than the root diameter of the thread to insert between the chuck and taper, to cause the jaws to engage.
