If these work out it will be the find of the century. Good looking quality. Time will tell. I will repost an update once I have these in process.

Comes in nice plastic container for each size, not gotten around to using any except for testing the couple er32 holders I have, updates when use them some

These arrived fast and were exactly what I needed for a cnc mill I had purchased without tooling. Tapers seem well done and measure to spec. The pull studs are I believe some older HAAS style so they were a bit useless but that’s a fairly minor complaint, as is the fact that ER16 collets are pretty tiny for CAT40 holders and will be of limited usefulness. I do wish there were more options to buy this set in smaller groupings. Maybe a set of 4 ER32 holders without pull studs, for example. Or a run of SLN holders. Or a couple FNB holders.
I’ll probably end up buying another set in the future since the price is right even with the less useful bits but it does feel wasteful having the studs and ER16 collets sitting in a and unlikely to be used.

Tool holders work great!!!!

I purchased one of these sets and there was minimal runout and decent quality. After reviewing the first set I decided to purchase another.
Verified Customer –
Was skeptical because of the low price but was pleasantly surprised. Every but as nice as my albrect chucks. Well made, nice smooth action, grips well. I’ve bought several.
Verified Customer –
Item as describe. Love it. Thank you.

I accidentally ordered the wrong size chuck and couldn’t use it, so I can’t really give an in-depth review. However, it was heavy for its size and felt pretty solid. It turns pretty smoothly when you open and close it. Unfortunately, Vevor doesn’t sell the MT2, which is what I needed; otherwise, I would order another one. If you plan on buying this for your Vevor lathe (I purchased the 8″x14″), I recommend measuring your lathe first. I bought this because the Vevor lathe I purchased said it uses an MT3, but it uses an MT2. If you are buying a lathe, I would wait until you receive the lathe before you buy this chuck. I’m not sure how many other Vevor lathes have product descriptions that list the wrong size.

I have not used all of it but several of the set screw and collet holders are good with reasonable runout. The holders have some sharp burrs that need filling so you don’t cut your hands while handling.
Verified Customer –
Excellent value for tool holders. It’s a great beginner set with room to expand. Way better priced then most
