You might be able to remove the broken tool with some dental picks. Harbor Freight Item #93514 $3.99 6 piece set or ask your dentist for some old/broken ones you can sharpen. 2500 RPM for a 1/32" diameter bit is extremely slow, even in wood. Google toolstoday feed speed wood May want to just spend the $ on 1/32 end mills which should handle side loads better than PCB drills. http://forum.vectric.com/viewtopic.php?f=28&t=20415 I had an awful time milling a 14DP gear in steel with 1/16" and 2mm and smaller mills at 5000 RPM. Broke all those I had by the time I got the gear finished. If I had the 10000 RPM version the job could've been done in half the time and probably wouldn't have broken so many end mills. I've been thinking on making a high speed spindle to mount to the side of the head on my PLM2000 with a 1:2 step up belt drive. One locating point would be the 1/4" spindle lock pin hole. The rest I'd have to make a bracket to bolt on. Something you could try with those teeny mills is get a really good variable speed rotary tool and make a mount to attach it to the side of your mill head. Make a lot of shallow, high RPM, high speed passes to save the cutters. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
