Noga DG0039 1.97" x 4.72" x 2.17" Magnetic Holder Bed-286 Lbs Hold

All mag bases have m8 connections. This one has M10, so it's basically useless until I figure out how to connect my m8 stuff to it.Read description again and no mention of this. Should come with a bushing.

This Mad-Base Magnet is strong and well made. NOGA seems to be this beat Mag-Base products I have ever used.

It is exactly what I wanted

very powerful magnetics

Very strong! I use it to hold light work on my drill press.
