has anyone delt with this outfit,, they have a new 12m x 1 er16 collet chuck at a good price,, the standard unimat db/sl version is kind of a unobtainium part,, few offered prices crazy..

I use them quite a lot. They make some items themselves and others are Chinese imports. I have had few complaints but too cheap may mean too low quality.

this looks like one they are making or modifying,, not a give away price,, most likely better than one I tried making a while back..

I bought their similar Myford ER32 chuck a few years ago, and it had ~3thou of runout. I contacted them and they sent a second one - the replacement has ~7thou or runout. They issued a refund and told me to keep the chucks which I sometimes use on less critical setups where the concentricity isn't important because the job won't leave the collet before parting.

I ended up getting the RDG 2-part ER32 chuck system because it allowed me to turn the spigot for the rebate in situ. Even that one has around half a thou of concentricity error between the rebate and the collet seating, but that's near enough for anything I do at the moment.
