I notice in Rob's tool, the insert appears to be presented at 90 degrees to the work; is the necessary geometry incorporated into the insert itself?

After I first saw their fly cutter, I had thoughts of making a holder to use one of my lathe insert holders as a fly cutter. Does that sound like a viable option?

Hi there Pete , 

Thats correct , the TCT is mounted at 90 ,and they are for a lathe tool . the reason being I have about 10 boxes of this tip , being a hobby shop we/I use whats available , no point making a tool I would have to buy tips for . Yes you could go to a far end of a fart to get that 10 seconds off the time it takes to machine a part with the ideal tool for the job ,but this is just a hobby for me so if it takes 1 hour longer I am not that arsed . What I am trying to say is make the best of what you have at your disposal.  

The results speak for them selves , and I have used a grand total of 2 TCT since I made the fly cutter .

These are for my bench vice jaws , 4140 or there about's .





And to answer your other question about using a lathe tool ,,,,,,,,,,,,,,HELL YES 

Here you go , one of those cheep flycutters  , you know the ones ,come in a set of three (really handy around the shop ) and a 1/4 LH TCT lathe tool . 




Thats the cutter bar for the larger fly cutter . Even a bench top mill will get a finish on a part like that. 


I would like to end by saying thank you to the lads for all the kind comments on my work . much appreciated .


Cheers Rob
