Single Flute vs. Ripper

I remember reading a post on here saying that for cutting plywood, it is best to use a very high feedrate and shallow but, with a single flute cutter.

There seems to be general recommendation of single flute cutters for general wood routing. Has anyone compared these to 'ripper' types? I've read that ripper bits eat up wood cuts, but how is the finish of the cut in comparison to a single flute mill?

I'm thinking about getting one of these at the bottom of the page - http://www.cutweltools.co.uk/files/w...%20carbide.pdf.

Probably just the same as it is in steel or aluminium.!!. . . . Inferior.

I could have actualy tried it for you with that exact cutter but I snapped the bleeding thing while cutting 3mm box section and wasn't impressed with my self.!! . . Woz Being greedy and lazy I should have known better. :redface-new:

For low spec jobs I use cheap router bits from toolstation - it is only £1.20 a piece - worth to try
I use 3 and 4mm for acrylic and mdf - if it brakes - no problem for this price it doesn't hurt at all. So far I have nothing to complain about them.

So could I, except there's a 98kg sheet of aluminium waiting to be cut and somewhat in the way on my router at the moment!

I used to get those but they never lasted long and where nowhere near as fast as the 6mm single flute carbide cutters. Get yourself a few ... I guarantee you wont regret it. It's a HUGE difference.

HiltonSteve made a post in his build log on a few cutters and detailed his findings on each, he worked with ali but it maybe of intrest to you:

I got some carbides from chinese shop - not ebay- I don't remebmer shop or website name - it was somewhere on this forum - crap, crap , crap, they brake at acrylic or aluminium - I did try few sizes and was very disappointed. Then I decided to go to toolstation and I don't regret. So far I cut few sheets of acrylic 3 and 5mm thick and some 9 and 18 mm mdf from wickes with great success. I wouldn't pay at least 10x more for cutter to cut so low spec jobs.

The cheap 6mm SF 5 for £20 something quid of ebay are excellent and the don't break very easily. I've only broke 1 and that was trying to cut that really hard resin impregenated MDF in 1 pass 13.5mm DOC @ 7mtr/min after it had cutt countless jobs in Ali as well has 1 pass 10mm DOC @ 5mtr thru same resin MDF. It was well shagged and had every right to give up the ghost. . . . . IMO they are spot on and worthy every penny.
