Topic tags/keywords: router porter cable tool speed question

I had an old Porter Cable Model 690 single-speed router (vintage 1990) that I have given to my grandson. Does anyone know that tools rpm? Thanks!

Take it to a repair shop and they will scan the RPM for you.

ps. if it’s the 1 1/2 vs the 1 3/4 I will have to look later when I get home then its 22,500.

Thanks everyone – I had found the 27,500 speed for the 690LR model, but this 690 has no suffix. Brian, I was actually asking about a 690 Brother Bob has of similar vintage. Chances are it’s the 1-1/2 HP – and I hope it is. The reason is the 1/2” quad-cut round-over bit he just bought has a recommended max rpm of 16,000. Even 22,500 is still a lot more than 16,000, of course. As to the router table, Brian, hints are cheap – and worth every penny.

GMman, great idea to get the actual rpm.

Hi Dave—
That was hard info to find! If it’s the older 690 (no letters after it) with 1-1/2hp, then it’s 23,000rpm.
Found the info on a Popular Woodworking page dating back to before 1999:
