Arbor is good, somewhat well balanced but it's a 3/8 flycutter not 5/16 as it states. Even tho I'd rather a 3/8 cutter, I bought and sharpened some 5/16 blanks before realizing it's actually a 3/8. So there goes $20. That's pretty upsetting to me. I could have invested that $20 into a better arbor.

Like others have reported, I received a 3/8 bit fly cutter, despite that the description (still) says it is for 5/16 bits. That wasn't a problem for me - in fact, I was kinda hoping I'd receive the 3/8 size - but I docked a point for the misleading description, anyway. Functionally, this fly cutter is very well balanced and produced just barely perceptible vibration at 600 RPM, and a lot less clatter when actually cutting than a much smaller fly cutter with a straight 1/2 shank. Also, there was no difference in bit height above the fixed jaw of my vise when rotated 180 degrees, which means no wobble. Shown is a test cut in 6061 aluminum plate at 0.1mm depth of cut, 600 RPM and hand-cranking the travel at a reasonable speed on my PM-727M mill - very pleased with that result, and I suspect that a HSS tool bit will give even better results, especially in aluminum (I just need to grind one - all I had on hand was a 5/16 bit for the aforementioned smaller fly cutter).

Description says 5/16 but found that the slot is large enough to hold a 3/8 tool. Looks like the head and the R8 shank might be separate pieces, possibly pressed together, something to consider if planning to take heavy cuts. Works well enough for light cuts on steel.
