Happy New Year!
With a 3.175 mm chuck it's the only way to make larger holes.

Actually you can change the collet to a bigger or smaller onehttp://www.ebay.com/itm/New-ER20-12Pcs-Spring-Collet-Set-For-CNC-Milling-Lathe-Tool-Engraving-Machine-/291676115522I bought one of this sets and it's nice to have around, I usually keep the 3,25mm. but sometimes I'm using smaller ones for drill bits.
ER11 collet should come out - not much sense in having a one-diameter-only collet.E.g. http://www.banggood.com/7pcs-ER11-1-7mm-Spring-Collet-Set-Chuck-Collet-for-CNC-Milling-Lathe-Tool-p-998449.htmlJakob E.
most of the time is spend mounting the work on my mill. then doing it a second time when the work slipped during milling.... a aluminium plate with holes in a pattern seem to work well for smaller stuff.my ER25 collet chuck has a screw holding it in the morse taper - yours won't I guess. but if you remove the nut, then the collet is hold in the nut and can be taken out with a light sideways motion while pulling it out. the other collet (you usually have a set of increasing collets with a 1mm range per collet) needs to be put in the nut a little sideways. it then clips in and can be screwed into the chuck.- michael
Did you mist with sprituosa of any kind? It will improve performance. I found that light passes, 0.5 mm, not so slow works fine. Risk for clogging if going too slow.
