I put a collet holder chuck in the noname mill drill a while back and it works great. A lot faster and easier than constantly tightening and loosening the drawbar whenever I change anything. Its got a nice collet closer wrench and a couple flats on the body that I can throw a regualr wrench on to tighten and loosen quickly and easily. I like it so much I bought a similar one for the RF30. It works pretty good, but there are no flats on the body for a wrench. That means I still have to flip the top and hold the pulley when tightening up a collet. Its tight enough for the small stuff, but when I was doing some heavy (for me) face milling with a 1" end mill I found that it seemed to walk up in the collet. Holding the pulley I really have no way to judge how tight I am making the collet, so I figured I'ld mill a couple flats body of the collet chuck so I can use a wrench like the one in the smaller mill drill. (never had a mill move in that one) Any suggestions?
I mean besides going back to using the straight R8 collets. Obviously I'll have to use them to mill my flats, but then... For the most part the convenience of using the collet chuck is a HUGE time saver.
