  • Works well, seems well made, extremely reasonable price
Size: 1/4 Collet - 2 Pcs
I use a shared workspace and recently discovered the 1/4" CNC collet was missing. Super annoying situation. I already buy and use my own bits rather than the shared ones, so I shrugged and ordered my own collets as well. I like that this is a two pack. I kept one for my own use so I don't encounter this problem again, and then donated the extra 1/4" collet to the shared tools. Great fit, great holding power, had no issues fitting in our CNC, and I was very happy at the reasonable price! ... show more

  • SOLID ER11 1/4" COLLETS...
Size: 1/4 Collet - 2 Pcs
This is a GREAT price for high precision collets, especially since you get two. The sizing is perfect for my CNC and dramatically increases what I can do with it. Fit the nut on my Genmitsu 3020-PRO Ultra like a glove. Very well machined and perfectly identical. Minimal runout and durable construction. Nice... ... show more

  • Works well in my Tormach.
Size: 1/4 Collet - 2 Pcs
Have been using these for a few weeks with no problems. Weight is comparable to other 1/4" ER11 collets that I have. Would buy again.

  • Works. Cheap and inexpensive.
Size: 1/8 Collet - 2 Pcs
These collet works. They will fit the ER11-A Collet Clamping Nut. They're a good value for the money. I've used them and ran them at 22000 rpm. They seem to hold up fine. However their quality is suspect to me. They are very light compared to other collets I have. I'm afraid to run them at very high speed. I would not get these again. I would rather pay a bit more for something from a brand name like IDC woodcraft or sainsmart. ... show more

I'm not sure where to lay the blame. One of these has had a real problem with getting stuck in my router.
