Nice selection of collets
I like these as far as price, size and workmanship. I have three other sets , ER-11, ER-16 and ER-25 and these are of similar quality. I have found that with just about any collet supplier that you are going to find some left over burrs inside the machined cuts in the sides of the collets. These are of no exception but the amount was very low and easily removed with a thin metal fingernail file. There are two collets that are larger than 1 inch which is a plus for this set as most charts for ER-40 only go to 1 inch. On the over 1 inch units you will be limited by the depth of the collet holder but by using a live center I can overcome the limited length of a work piece. The nice plastic shells that they come in are a little tight so I just slice one of the sides on the outer cover to make it easier to take apart.

1/2” Collet too small but Will work for holding round stock in lathe and milk though.
Clean economical collets.

not accurate
They may have missed a decimal point in their description. after verifying that my collet chuck was running true (close, about .0005" run-out), cleaned and mounted 3/8 collet, inserted a ground 3/8 carbide long shank end mill. measured .0025" run-out. indexed collet 180 degrees, run-out followed. Tried a 1/2" collet with slightly worse results (.003", and there is a raised lip at the back of the bore that was difficult to push rod past). I did not check any of the others in the set, I will be returning them. A collets whole reason for being is to be more accurate than a three jaw chuck, and these do not achieve that

Get what you pay for
runout on 1/8" collet is sadly visible to the naked eye making it useless

Collets
They seem to be a good choice with the limited use I've had so far.
