Smallest sizes DO NOT WORK well, but everything 1/8" and up seems great.
I have had these for about a month and have used quite a few of them. I purchased them to use in the lathe and in my drill press for some light milling operations. I used the 3/8 and 1/4 collets to hold mills in the drill press and did a runout measurement using my dial indicator. Even in the drill press, I got just under .002" runout with those two collets. When I measured just the collet chuck I was right around .001" runout. I had similar measurements but slightly better in my old mini lathe. Today I went to drill a hole in metal with a 3/32 bit and figured I'd be better off using the collet. Unfortunately, I found that the 3/32 collet made the bit wobble around like crazy! I then started checking and found that the 1/16 collet did the same thing. (When I reinstalled my Jacobs Chuck to drill the 3/32 hole, it had far less runout than the collet) However, the 1/8" collet was back to the .002" runout I had measured on other collets. Upon further investigation, I was able to determine that the 1/16 and 3/32 collets are cut differently than all the other sizes. It appears that in order to get the smaller size, they cut the kerfs nearest to the center with a smaller tool than used near the outside of the collet. (You can see what I mean if you look at the picture, the 3/32 and 1/16 are the same and then 1/8 has straight kerfs all the way through) I can't figure out why this has such an adverse effect on the runout, but I can assure you, it does. I still rated this set as 4 stars because it wasn't expensive, I got 25 collets and 23 of them work well enough for any job I'll be doing. I will probably just purchase those two smallest sizes from a more reputable company and make my set complete. Overall, I would recommend this to anyone with the caveat that you probably won't get much use out of the 1/16 and the 3/32 bits.
