ER11 Collet Set, 1Set 15pcs ER11 Spring Collet Chuck for CNC Engraving Machine & Milling Lathe Workholding Tool 1-7mm 1/8”，1/4”

A very affordable collection. I like that the collets were individually boxed in plastic. And it comes with a wrench for the tightening nut. A very nice set at a great price.

These have worked perfectly for my 3018 CNC .

Item did not have the extra 1/8 and 1/4 inch collets, ordered twice and both were same, returning both, didn't use them as i needed the 1/8 inches mostly.

excelente producto, se ve de buena fabricacion y material..

The only thing I did not like that it had a lot of sizes I do not use

I live in a rule area compare the prices up here Excellent bargain

Several of the collets have miss-ground cut marks on them. Obviously no one is checking these as they head out the door. I ended up with 6 of them that came damaged. You get what you pay for.

These are super handy and are well built.fit my fox alien and gemitsu. Er11 spindle

Great quality compatible with most snapmaker machines

We have ordered several collets from this seller and have been very happy with the speed or delivery and the quality of the collets.

Be Careful! The first two collets I tried were fine, but then I tried the 4mm collet for a new end mill. I noticed that it did not snap into the collet nut like the other collets and the end mill would not slide past the upper end of the collet. When I started the spindle it was clearly out of true. Had I not noticed and just started the CNC program the city would have snapped flown out into the shop space! Very dangerous situation. I took it apart and got it to slid past what must of been a burr at the end of the collet but was not able to get it to snap into the collet nut. The others in the set, at least the ones I tried, all snap into the nut. The snapping feature must ensure concentricity when the nut is tightened. I played around with it until it ran true but it continues to be able to be tightened while not being concentric. I will find and individual replacement from another source.

I purchased these for use in my 3018 ProVer, and they're great! Fit is perfect, and they're such a great value for the money! 10/10 recommend these to anyone starting off.
