A part of the review has been auto-translated.
good product , little amount of outage in collets is disappointing
These ER11 collets are working fine for small CNC routers. Each collets comes in with a plastic yellow case. I tried a few out with various bits, and they all work very well.
Arrived today. Material is quite strong. Was packed nicely. But the quality is just average. I used the 3mm collet and my drill bit just doesnt fit straight. It wobbles. Once the collet is inserted, it takes a little bit of an effort to tighten the nut on the holder. I bought it for using with the RS775 motor. The shaft is a good fit, though it will need a little bit of hammering and as the listing suggests - heat before inserting. But it is a tight fit, so no problem. I will recommend this for hobbyists, but probably not for professionals.
Arrived pretty quickly, in 2.5 weeks, seemingly quality, in work has not yet tried.
working good
Collet holder has very smooth running. Only the 1mm Collet does not fit in the Collet nut and the 1 mm hole is not in the middle.
qood quality
Very good build quality. Reguires some light re-bore to press fit on a 5 mm shaft
It's okay it's OK. High satisfaction and also quality. Seller = *****!
Looks like good. Not try yet. :)
