Temu and Shein are generally garbage merchandise. There is the occasional pearl. Any clothing purchase will be met with disaster. The sized are for midgets and the material is rags. I am probably not exaggerating on this one.

Hello Dick:
TEMU is a China group similar to Amazon. Small sellers ship directly to buyers in the USA. TEMU demands low prices and minimum sales. Lost somewhat in translation TEMU stands for "Team Up, Price Down".
Here is a Wikipedia link:
Some folks have had problems with quality and there are also questions of fair treatment of workers in China.
The latest news is the $800 tariff? exemption will stand for now.

Now if you want to try drilling a little better than our 61-80 drills, you can use the type below.

These are HSS centering micro drills that have a shank diameter of 1mm to 1.5mm.? They are usually Swiss or German.? They are not inexpensive Chinese products.? HSS resists breaking better that some of these carbides.

There was a question about sometimes getting a little eccentricity when trying to drill down the center of a small steel item.? What I suggest is to drill out the hole in your piece larger so as to take a brass rod.? Solder in place.? Face off and then re-drill to the smaller hole diameter that you need.? Brass drills easier.

Re: drilling small holes on a unimat
The first thing to get ahead is to make sure that your facing leaves as smooth a surface with the smallest "bump".
Next, have the right sizes of center drill.? For the tiny holes being mentioned, you need center drills from 0000 to 00.
In the US, Shars Tool sells these, $8 - 9 each.

Re: drilling small holes on a unimat
It is tempting when wanting to get ahead to omit the centre drill stage, I have done that in the past and regretted it.
Gently, gently catches monkey!

I have a small Jacobs chuck on a sliding shaft for hand feed that I used on the larger lathe I had but when I setup the Unimat SL it would not fit,? I also have a small Dremel chuck for fine drills I use this in the SL chuck but now I have the U3 I will fit it to a M14 x 1 back plate I always use M2 and M3 spot drills for centering my small work and use the center drills on the larger work.?

Re: drilling small holes on a unimat
You can also get a small chuck (looks like a Dremel chuck) with a 3mm shank and a cross hole that can be set up in the tailstock in a piece of round with a 3 mm hole to also act as a fine feed chuck.? Spot drill with a stubby screw machine drill or center drill, then switch to the hand feed chusk.? Those chucks are available from Amazon for less than $10. If that chuck is used with a drilled guide plate, that mitigates any offsets from the threaded arbor and the spot drill puts the start on center.
Clock makers will put a pin in one end of a double ended pin vise and the tiny drill in the other end of the pin vise, then pass the drill through a plate with the drill size hole in it as a guide (on the lathe's center of rotation).? The tailstock has a sleeve in it that allows the pin to rotate. Then bring up the setup close to the workpiece and slowly feed the drill by grasping the pin vise body and press into the part.? If the drill jams, let go of it and it does not break.
I have used variations of this method for all kinds of very tiny drills drilling into many materials including stainless.? Light oil is the best lube for the process.

Re: drilling small holes on a unimat
When saw this chuck I thinking great nice small low cost Chuck down to 0.8mm that is 0.0314" diameter.
I could miss read the data sheet at time day
?
The first had use a #80 it a pain find a chuck that work. The first was low cost it hold #80 but only for hand work. I found that said 0 to 5/32" [3.99mm] will hold #80 0.0135" [0.34mm] not cheap. Then told for just little more you can best. Back when it kill a good part of $100 bill with good shank.?
?
The #80 drill is a pain all the way around.??
1) Trying hold
2) Not bending or breaking?
3) getting started.
4) no way of sharing
But upside cheap
My solution is avoid that drill.?

Re: drilling small holes on a unimat
I can only what use and work it holds a #80 drill bit.?
I could not till you if still true today. I purchased mine in the early 1970¡¯s and still use it today for very small drill bits. Most chucks I use today are over 40 years old and are Jacob.??
?
Do Chinese make good chunks yes but only when got machine tool and basically after retirement.? Just short term use.? But flip side when I? first I purchased low cost and did last so when had the? money I purchased Jacob chucks and very happy after over 40 years.?
?
FYI a Decimal Size Equivalent 0.0135"
Thd add for a Jacob's chuck is Jacobs Keyed Drill Chuck
Model #0, Taper-Mount, for 0.014" to 5/32" Bit Shank Size
?
So slightly different of 0.0005
I used my chuck to #80 drill bit is Chang in since or someone round up.
?
?I have 2 chuck they both hold #80

Re: drilling small holes on a unimat
The Dremel chuck has a 8mm x 0.75 thread. But other threads are available. I have a Dremelesque coreless drill bought from Aldi and that has a 7mm thread. The Dremel system also supports collets, but normally only one size is supplied. The other sizes are available yo buy via fleabay or Aliexpress. The collets work well for small size drills.

I duplicated the the threads on the dremel, this would be the dremel's spindle. Now I can put that in any unimat chuck and use dremel's tightening nut to hold the collect which holds the small drill bit.

One can buy these collects and the nut that tightens without purchasing a dremel. I asked their customer service what the thread was on my dremel's spindle and they supplied the answer.

Re: drilling small holes on a unimat
Another option for holding tiny drills is a pin chuck, held in a regular chuck. I have an Eclipse one, which I have used in a Unimat and also in a bench drill. Not as good as a collet chuck, but still useful.
(Spear & Jackson own the Eclipse brand.)

Hi,
There a number of cheaper suppliers on Aliexpress, not the first option for you guys over the pond.
Jus search for "Dremmel chucks".

I got mine at home depot. Should be on Amazon, too. Yes:?
Says it is for .008-1/8th inch, so might not work for some folks. There are a bunch of other miniature chucks, and pin vises on Amazon, though, so still worth looking.
