I’ve had my X Carve for several years now. Right away, I bought the 1/4 to 1/8 adapter. No new collet nut needed. I have a fair assortment of both size bits, but, as I got further into carving, I have been trying to “standardize” on 1/4 to simplify tool changes. I’m using Aspire to develop tool paths. As much as I can, I run the tool paths consequently, just changing bits and re-zeroing Z (only) if the machine is still online.
Of course, if the job is very long, I take a break and start up later. It may be a little more difficult to get some smaller bits with a 1/4 shaft. For example, one of my best bits for finishing is a 1/16 ball-end. To get down to 1/16 from 1/4
, the bit is tapered as shown in the photo. The taper may or may not be a problem depending upon the depth of cut and what you’re cutting.
