Hi all just wanted to get some feedback from the Pros on cleanup of color core. I machined some .25 color core with a .0625 bit which is new to me. Used a 4 flute because that is all I had at the time. I have found that single flute or a double flute in the larger diameters leaves much less clean up. Just wanted to get some feedback from others. Attached is a few pictures

I have been using a 3M RBA-1 rivet brush- bristles are about 3/4" and
very stiff but it doesn't scratch most surfaces. Gene

I also use a brush, some cheap plastic bristled brush I found in the paint room. It does I good job a breaking off the bigger pieces. I have also found that when I set the toolpath running the profile before the clearance produces a much cleaner piece. sometimes a heat gun or torch can be useful but its easy to overheat your board. For the most stubborn pieces I have an old 30 degree engraving bit that I use as a scraper but that sucks if your piece is higly detailed

I know its that harbor Freight guy again! :D I do a lot of plastic stuff. The sets have nylon, brass, and steel bristles. The nylon for shiny plastic but on some textured surfaces the brass works to. Russ

I would have run the tool path again. In my experience that help a lot on the small tool paths. Need to find that 2 flute bit also.:) What I use to clean out the grooves is a sharpened awl mine has a rubber handle on it . It work pretty good to clear it out.

Just watch out for the brass brush discoloring light material. I guess it leaves a petina color. I used it to get the fuzzies off of a piece that was to be painted.
