Fly Cutters are cool

[Janderso]

All I have is a small 1/4” shank import fly cutter.
I’ve seen the finish that can be achieved by a properly made tool.

I finished this today. It works beautifully!
This is a 5/8” shank insert holder. This appealed to me for two reasons.
Changing an insert is quick, cheap and easy. I also wanted some stability for this size of cutter.

If you haven’t made one, put it on your to do list.

Just received the tool holder for the "free" corner of a CCMT.

I certainly see the appeal of an insert, but HSS is far better at getting a good finish with very small depth of cuts. Anyway my fly cutter uses an HSS bit and has a six inch swing. It works great at removing just a thou or two with a finish as smooth as glass.

Not necessarily. It all depends on nose radius, although I can see where HSS has the advantage there.

@Janderso Hey Jeff, where did you purchase the carbide cutter from? I already have a couple of fly cutter bodies but looking for insert cutters.

Same thing @MrWhoopee. Could you provide a link as to where you purchased yours? I have a bunch of CCMT tooling, and it would be nice to utilize the "free" edge.

Fly cutting is fun, especially aluminum. What's not fun is cleaning up all the chips!

It's the left-hand version, SCKCL1212H09

The shank is 12x12mm (haven't been able to find smaller). I had to cut it down to 10mm to fit my fly cutter.

Thank you Mr. Whoopee!!

I have some 5/8” HSS blanks. I plan on grinding a left hand profile to give me options with this tool.
