I want to machine a thin piece of stainless sheet(and some fiberglass too) for an instrument panel. I am not happy with the results I'm getting with an endmill, and want(or think I need) to get a flycutter.
Looking at the usual MSC/Enco/McMaster, I see two basic variations. I see "Rip Flycutters" and "Fly tool cutters". Other variations include the "roughing and finishing fly tool system", etc.
From what I can tell, the rip flycutters can take a 1/2" bit, which would work nicely with my existing indexable holders. The rest take either 5/16" bits, or 1/4" bits or thereabouts.
My first concern is how do I set this up? Assume I want a 3.125 inch hole, +-.005. Is that possible with the way these bits are held/clamped?
Second concern is that the rip cutters do not appear to hold the bit at an angle, which may make it difficult to cut thick materials.
What's the best way to go about this? R8 or straight shank is acceptable.
