Miniature Drill Chuck

[devils4ever]

I purchased that exact product not long ago. In my searching it was absolutely the least expensive sensitive drill attachment + chuck that I could find. The chuck was a bit 'gritty' at first, but cleaned up pretty well. It'll never be an Albrecht, but the whole thing is pretty well made for the price and does the job.

I have used mine only in the mill, with a 1/2" collet, but I wouldn't hesitate to clamp it in my drill press chuck. I have a small-ish Rohm chuck that I routinely stick in the drill press chuck with no ill consequences.

I ordered this one and I'll see how it works out. If it doesn't, I'll return it and get a better one.

I have this Vertex keyless chuck for this type of work - outstanding quality and with the pound at all time low, hard to beat price wise (I buy from this place in the UK all the time):

Combine that with a JT1 to 1/2" drill chuck adapter like this:

I was given this keyless tiny chuck that I put in my larger chuck to work https://www.ebay.com/itm/175348476048 https://www.ebay.com/itm/175348476048

I have a number of chucks which can seat drills of .007" diameter. Most are keyless but the Jacobs 1B also will. When using #92 drills or 0000 center drills, runout became an issue. My answer was to make my version of a Tru Set adapter. O made two, one with an MT1 shank and another with a 3/8" straight shank. They are made from brass and have four adjustment screws and four locking screws.. It is possible to adjust runout to a few tenths. Pictured are a Phase II and a Jacobs 1B.

That's a great idea! I have a Sherline MT0 adjustable holder with a 0 – 5/32" chuck mounted on it that I got as part of a lot at this year's Cabin Fever that has been sitting in a box: I'm going to add a ring so I can control the adjustment. From Sherline's website:


I already have an MT0 – MT2 sleeve. Or, I can make a new back with the adjustment screws & a 0.375"Ø shank to use in my Joe Pie (ish) tailstock adapter.


Thanks, RJ!

After reading all sorts of negative commentary on the newer Jacobs chucks, I invested in a Taiwan Golden Goose 3/4" ball bearing chuck. Seems like a great piece of tooling to me. They also make smaller chucks, and I believe Vertex chucks are rebranded Golden Goose products.

I received my mini drill chuck from Amazon. It seems to be of decent quality, but I haven't used it yet. I have a (dumb?) question on assembly. Do I remove the little screw at the end of the arbor to mount the chuck? Or, do I just press on the chuck as is? The screw seems to be somehow related to the spring inside the shaft (I think).

Don’t attempt to change the arbor: different designs are assembled differently and unless you plan on buying a second one you’ll be asking for headaches.

I cannot say for sure for yours, but typically yes.
Normally that screw is used to pull the taper together and is LEFT HANDED!

Edit: make sure both halves are spotlessly clean before installing.

The screw turns in both directions, but does not come out. I think it's connected to a spring inside the shaft.

Just checked: my Jacobs #0 chuck does have a through hole, but it's the same size as the end of the JT0 taper so the screw on the end of the taper would pass right through the hole.
