Hope you Grizzly folks don't mind my posting here, since there is lots more traffic.......I have one of the RF30 clones (I think Enco) very similar to the Grizzly G3358, or the G1006. My question is about what tool holding to use. The Mill/Drill has an R8 spindle. I know I can use R8 collets for holding both end mills and drills, but that the shanks have to be the exact size of the collet. Taking into consideration the tram issues if the head is raised or lowered, as well as the tool shank sizing on the R8 collets, I am wondering about getting an R8/ER32 collet adapter to use. My thought is that using the ER32 collets gives me a bit more of a range of shank sizes to use if I needed to get an odd drill here or there. The ER32 collets and adapter would also offer a similar protrusion from the spindle if I needed to change to a drill chuck or an endmill holder. My thinking is that this would help remove the need to raise the head of the mill while working on a part, and avoid the re-tramming issues with round column mills. Am I close to being correct? What thoughts or suggestions are there on this? What other considerations and options have I overlooked?
