Milling Tool Steel
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. |

Can you disassemble the thing and _then_ get at it with a bench grinder (this would relieve any anxiety about getting grit into the works). You don't really need flats -- it may be easier to get a nice hard drill bit and make a few holes, then make a matching wrench (I don't know what you call it, but it would be one with a semicircular gullet and a reasonably hard pin that matches the diameter of the hole). -- My liberal friends think I'm a conservative kook.

Were they accidentally left off, or does it have pin wrench holes? Do you have a catalog picture? I'd rough it to within about 0.005" with an angle grinder and then surface-grind the flats parallel. A rubber strap wrench might have enough grip. jsw |

I cut it with a 1/4 solid carbide end mill. Ok two of them. When I got a little impatient and tried to hurry it broke the cutting edges right off. I also noticed when it was "WET" with oil it cut, but when it looked even a little dry I could hear it impacting. Had to hit it with a few drops of oil every 1/8" or so. |

I'd coolant flood and grind the flats.
A surface grinder would do it nicely. You don't want to heat the part or it might fracture or loose strength.

Its so nice to be able to put a wrench on it, and tighten it up right. I have to say I have a lot more respect for you old farts who stood there for hours turning the handles on a mill so slow. I can also appreciate that comments about "feeling" when its right. When it felt right it I could just watch the chips pile up. |
