I have a lead on an old stock 14" blade at a great price but I have never seen this kind before. Do any of you have any experience with a blade like this? I just want to make sure its not a concrete blade. Its 14" x .050 so I thought being that thin it might have been for lapidary. thanks Chuck

I use a Felker on my 24" with good results. It is a concrete blade and as far as I know that is all they make. Concrete blades will cut rock, but you may need to dress them more often.

Chuck I have a 14" Hilquist saw. The blade they recommend is a .060 for smoothest cuts. I like the one I have and it does cut smooth! Not this brand but size sounds right with thickness.

Didn`t see that rpm rating until now. That may be a problem.

I went ahead and bought it because the price was too good to resist. It should be on its way now. I went to Barranca Diamonds website to look at there blade speed chart and for a 301 series blade they recommend 820-1230 rpm so this one being 1085 is right in the middle of that range. I will have to check my pulleys since I have never paid any attention. My saw is a very old beacon star so I am sure its set up for the slower old style blades right now.
Thanks for the input, at least it made me check into it!

Chuck,
I can't say for certain, but it looks like my old blade on my 18" saw. Mine had a notched rim. My blade was well used before I got it, but it cut fine as long as it was dressed. It did struggle with really hard materials like Flint Ridge or palm bog. Most agate and jasper was fine.
Good luck with it!
Chuck

Felker made lapidary blades back in the day. It should work well for you.

It will be a good blade for you. The one on ebay is only $20 less than a BD303, I would be surprised if it sells. 2 inch in your motor and 3 on the arbor will net you 1150 RPM, will be fine for the blade.

Felker made great blades, however all I have seen are directional so make sure to run it the right way.

I got the blade and it still had the instruction sheet that called it a lapidary blade for agate, pet wood etc ... It actually called it out as non directional which is new to me since all my blades have been single direction up till now.
did I mention I found it on etsy for $50 .... could not pass it up. my trim saw blades cost that much.

Yup, what John said. I've worn out a Felker blade or two in my day, but haven't seen their lapidary blades for a few years now.

I'm pretty sure all the old US made notched rims were non directional. The diamond mixture was brushed on by hand so not oriented in any way.

The old Felker blades had the notches put in the rim at an angle.
