spoil board fly cutter question

[jrj5x5]

I am thinking of purchasing the grizzly G2861 Fly Cutter to surface my spoil board.This bit with 8 inserts is less than $100
shipped.
Is there a major downside to using this tool that I am missing.
I just hate paying out $250.00 on a standard spoil board cutting bit I will use twice a year.
Thanks Jim J.

I always think of wood machines when I read "spoil board." Never have I seen a $250 Fly cutter. Usually they are the cheapest surfacing tooling around. The shell mill you are looking at is a nice one for removing metal material quickly. It's harder for a nice even surface though, you will really want to make sure the head is trammed in perfectly. An out pf tram head will make high and low ridges which are are a cosmetic problem, but still a problem.

How do you get the R-8 shank in a router? And how fast can you safely spin it?

I would use a adapter.
And your point is one of the reasons I ask.
Can I safely spin this bit at 10000 rpm's?
Anyway I have posted this question on a couple of other sites I frequent and have had some alternative ideas tossed out for me to try.
Thanks for the feedback.

i learned a big lesson about highly polished machine vs cnc bits recently, it was not a good idea

I'm having a hard time imagining that fly cutter running in a router. I guess it could be done, but is it actually balanced/rated to run at high speeds? How are you going to make the R8 shank work with a 1/2" collet system on a standard router?

Save yourself a lot of work and aggravation and try: C1261
I just picked one up and it works great in my spindle. Only 1.5", but still a decent size for smaller spoilboards.

Hi,
I use one of these on my router, It uses indexable carbide inserts and is made to be used in a router. I paid ~ $140 when I got mine. You need to get the cutter and a Shank for it. Once you have the shank you could get multiple sizes and swap the shank. It works well as long as the router is trammed properly.
