Can anyone recommend a 1/8" collet for the Bosch palm router? I have a few of the 1/4"-to-1/8" reducers, but bits keep slipping down resulting in broken bits and trashed, not-cheap 6061 stock. I'm cutting with 1/8" two-flute carbide ballnose endmills, which works pretty well until things start slipping. The collet and reducer are about as tight as they'll go, though the length (22mm) of the bits prevents them from seating correctly in the collet. I'm looking for mills with a longer shank, but many of them are very expensive. Suggestions?
