ER collet variations!! BEWARE

jeudi 29 janvier 2015

A word of warning, NOT all collets are the same. I recently bought an imperial set of Chinese ER25 collets and bought a separate one, a vertex 12-13 mm. Thinking that there was a standard that they would be made to, DUH, wrong. The original set I had are 4 degrees, the latest set 5.5 degrees, while the vertex is 8.5 degrees and is very short.

Has anyone else come across this problem??? The latest set I could probably get away with using, but the vertex is way out, so it's for sale if anyone is interested.
