Topic tags/keywords: radial arm saw saw blades delta delta ras ras blade

All,

I just rewired my 1993 Delta 33-890 RAS. It runs like a top. At two horsepower, it should be able to cut through most anything I would want to cut. Currently there is a 12” 80 tooth blade on and I wanted to upgrade. I know I need a negative hook angle, but I have a few questions:

What is simply the best blade out there for an RAS?

What are the “value leaders.”? You know, the ones that aren’t quite as nice as the best, but still awfully good. Just in case I don’t want to spend $150.00 for a blade.

Can I use a regular dado blade in my RAS? Like I said, I have a 12” saw, but I have an 8” freud dado set. I’ve only ever used it on my table saw and would love to try my RAS.

I plan on using my RAS for cross cutting and dadoes. I don’t imagine I will every turn the motor in any way but 90 degrees. Will this blade well just in case I decide to try something crazy like ripping, beveling or miter cuts?

Thanks guys, I’m looking forward to your responses.

Dwain

You won’t go wrong with a Forrest blade.

They aren’t the cheapest quality blade by
fair shot. I’ve owned a few. These days I
think the computerized manufacturing of
saw blades has got so good I wouldn’t be
overly concerned with brand unless you’re
looking for a thin-kerf blade.

There are bargains to be found on 12” and
larger blades from many makers on ebay.

Most name brands work fine and some last longer. I only run 10” on my RAS. The freud dado’s will work..

I would try your best ts blade, and see how you like it.
I have a 12” Dewalt 7790, with a 10” positive hook blade. I really don’t feel it needs a negative hook blade. In my experiences with Rae’s, it seems the lower HP saws, like Craftsman saws, really try to self feed, but higher HP saws, just cut.
Try a blade you have and see.

Knot Scott has excellent advice on blades, not sure if it applies to RAS, but it’s worth reading.

I have a 10” DeWalt RAS (old school saw) that I use with a Freud blade that has a -5* negative hook. It was my understanding that a negative hook was a safer option but I’m not sure if they make a 12” version.

I’ve used an 8” dado set on mine and it worked beautifully. If I ran a pro shop I could see keeping it set up to do dados exclusively. Fast and accurate, especially if you’re cranking out allot of duplicate cuts.

To me the best value RAS blade is the Freud LU91, and it’s the one that’s been mounted on my RAS for over 20 years (for the record, it sucks at rip cuts…but I don’t rip on an RAS). The one I linked from Router Bit World doesn’t have the awful red coating and is likely the best price you’ll find. I’ve bought quite a few from them and have always had excellent CS.
