Eccentric Engineering FoR
|40 forum posts|
Has anybody used the Eccentric Engineering paring tool. I'm thinking of going for it but would appreciate any feedback, its not cheep. I have been using their tangential tool for some time and have no problem with the quality of their products, but would like to know if this parting tool performs compared with other tools on the market.

Heard very good reports about this one **LINK** Can't afford one myself. John

I would enthusiastically join those John has heard giving good reports about the Q-Cut. I bought one a few years ago, and now I wouldn't use any other type. I've never had a single problem parting off a variety of materials, never needed to use a rear tool post. I have since acquired a larger one of similar pattern for my larger lathe, and that one happily parts off under power cross feed (to my great regret I don't have pxf on my S7).
Though the blade design provides a good rigidity, I think it is the tip geometry which is the really crucial factor, it curls the swarf inwards do it never jams in the cut.
The only time I use any other type is when I'm parting off or grooving tiny parts like micro tubing for O gauge work, when an Interstate Mini-Thin set is the dog's b******s (though a bit expensive).
Remember, the quality is enjoyed long after the pain of the price is forgotten.

Plus one for the Q-cut. Never a problem on either the Myford or Hardinge.

I agree with Q Cut comments, Myford S 7 and Harrison M300, never a problem.

I would also be very interested in any feedback on the Eccentric parting tool.
I note the enthusiasm for the Greenwood tool and have been put off in the past by the price of it and also the cost of replacement inserts at £9.95 each.
The Eccentric blade appears to be easily resharpenable (is that a word??) so although the initial outlay is similar the running cost should be less.

Jim, I understand your concern, but both my Q-cut and its larger brother (like KWIL, S7 and M300) are still on their original tip after 10 years (S7) and 4 years (M300) of admittedly light amateur use, and showing no sign of wearing out.

I have used their tangential tool holder for a few years and find they work very well and are of good quality .
The parting off tool holder as i see it is nothing more than a tool holder that can be turned upside down and uses a pretty standard cutting tool with a slight concave in the cutting surface , this is better than a flat surface but not as good as the Q CUT as i think the concave surface is more pronounced on the insert .
If your Chuck is a screw on type you will need to run the tool holder as a rear part off tool as to mount it at the front you run the machine in reverse as the tool is inverted .
I went the way of a tool similar to a Q CUT and run it in the rear toolpost as my machine is a little flimsy .

Hi Nobby, That looks like its fair buzzin round, no coolant and with at least 1" overhang. You must have your angles and rakes about right. I made a similar back toolpost for a Boxford which used a modified Myford 7 topslide, and it worked pretty well.

Mini lathe in action, ten minutes ago.
2" diameter EN1A.
Home made front QCTP toolpost and toolholder using rectangular section 1/16" parting blade (Arc Euro)
Mini lathe modified with roller bearings, and now 3-phase VFD. (the groove to the left of this cut was made using a wider tool and the original DC drive)
No coolant, not even a smear of cutting fluid.
Some noise, but just change teh cutting spead until comfortable.

I have had unhappy experiences with a carbide inser cutter which cost a lot of money and so did the inserts that I managed to break regularly. Put it down to poor workmanship if you like but parting off on my Warco 918, which is quite a lightweight machine, has never been a joyful experience. That is until I fitted 3 phase variable speed drive, since when parting off has been an absolute doddle using conventional parting off blades in a front QCTP. Any material cuts at speeds that I would not previously have dreamed off with the old set up. Why there should be such a significant difference I don't know.
