I have an X3 on order and I'm working on my tooling purchase. I'm not sure what shank type is best for a flycutter. I've seen R8, 1/2 straight, and 3/4 straight shanks. I'm going to use a quick change collet chuck so the straight shank tools look like they will be more convenient but I'm a little concerned about swinging that tool around when is is only gripped by the chuck. Flycutters look like fairly big chunks of metal. The R8 might be more hassle to change but I don't foresee the flycutter body coming loose from that. Any thoughts or experiences with these?

Enco has the following sets on sale
A set of 3 flycutters(3/4, 1-1/8, 1-1/2) - 1/2 shank for $7.29

A set of 3 flycutters(1-1/2, 2, 2-1/2) - 3/4 shank for $14.99

Or a single 2-1/2 R8 flycutter for $14.29

I think those sets are for the tool bit insert style(single point), in that case I would use what ever is convient. If you are using the carbide insert style then I would stick with R8. R8 style not only has the taper but aslo the pin to lock it in. I don't think you will notice the difference unless you are doing some really hard stuff.

BTW when did you order X3?
