Not 8mm, only 7.93mm aka 5/16in. 8mm shaft doesn't fit.

A bit oversized on the 8MM bore for the motor shaft. So it fits the shaft a slight bit sloppy. The rest of the ER11 collet chuck is decent. Still not horrible for the money, just wish the 8MM bore was correct.

This is a precision fit part.1.) You need to freeze this or the axle prior to installation.2.) Do Not Pound It On or you will probably damage the axle, or the collet holder. Any damage would create a permanent wobble.•Im a professional machinist and tool maker myself, and this is not advice. This is a Must Do.•Before you install this collet holder be sure youre ready. Do not install until you know that you’re ready to use it.•I haven’t yet needed to remove this but it wont be easily removed. Reverse installation process.⭐️⭐️⭐️⭐️⭐️ A 5 star product I would buy again. Might even promote this on YouTube.
