chipbreaker vs ruffer?4/18
I'm looking for bit to cut out an oval table top out of walnut, 2.25" thick. I'm not too concerned about edge quality, because I'll be profiling the finished edge separately.
I've seen offerings for solid carbide spirals in chipbreaker and ruffer formats, 2, 3, and 4 flutes, slow upcut and slow downcut. I'm planning on making at least 6 passes to cut all the way through.
My question is: what is the difference between a chipbreaker and ruffer, and what would work best for my application?
Personally I have used both roughers and chipbreakers, and I prefer using a rougher. I have two 3 flute roughers, one with a cut length of 3&7/8, one with a 2 inch cut length, both 3/4 diameter. They run at a higher feed rate, and for a rough cut it's pretty clean. Chipbreakers leave a better finish as they have longer straight portions of cut edge, roughers are serrated.
Very good luck with a chip breaker. Multiple passes. Yes.
A rougher would work just fine but I prefer a chipbreaker. I am biased of course but check out our Razor series, it will treat you well!
A ruffer will usually out run on feed rate vs a Chipbreaker. A Chipbreaker will usually give a little better finish. Make sure the collets are good. The part of the flute without the chipbreaker, will not wipe out the chip breaker completely if you are having runout in your router or collet.
