NOVICE ALERT!

I looked through the archives and couldn't find an answer to this particular question so I am deferring to some of you experienced types out there.

I have a Brevetti Prisma Maxi Saw. It came with 80 tooth blades but the spare blades that came with it were 100 tooth. We've noticed that with some mouldings the 80 tooth blade will chip the back side of the moulding. Is there a rule of thumb for which mouldings will cut better with the 80 tooth as opposed to the 100 tooth blade? Some Harder mouldings seem to cut fine with the 80 tooth but not all of them.

This happens with newly sharpened blades so I don't think it is related to the dullness of the blade. Can anybody share some wisdom on this one?

Thanks!
 
My blade sharpener (Rite-Way outta Long Island) says that the 80-tooth is better for our applications ... one would think that the-more-teeth-the-better, but apparently it ain't so ....I've been using a couple of 80-tooth jobs and I have no complaints .... of course, I don't use the couple of 100-tooth ones I have at the same time, so how does one tell....?
 
One time I was lazy and didn't change the blade on my saw to the wood blade from the plastic blade to just cut one frame quick. It seemed to cut nicer with less chips than the wood blade. The plastic blade (for cutting the polymer mouldings) has less teeth and the teeth are also at a negative angle I believe. So I've been leaving that blade in most of the time.
 
We have the Brevetti saw and have found that the 100 teeth blades cut much better just ask you described.

Blade quality I guess should become another thread,

Trust me, FF, the blade thing has been hashed over on this forum as nauseum! Some prefer el cheapo blades, some want to make monthly payments on them, some like 80 tooth, some prefer 100 tooth, and there is always the hassle of where to have them sharpened.

Do a search and you will find about 2 evenings' worth of reading, I'm sure.

I'd look at a source book-=-like PFM's suppliers' directory--and find myself a GOOD supplier of blades. The ones we use are combo blades adequate to saw metal or wood; have two so one is always in the box sharp then when we send the other out to be sharpened we always have one. One thing we don't go cheap on is the quality of building materials; I mean if you're selling $25-75 per foot moulding, don't even try cutting with an inferior blade.

Then again, there's lots to be said for ordering chop--less labor, the supplier knows how to do it with professional equipment, etc etc.
 
Thanks Guys! I reckon I'm headed back to the archives to find a high quality blade manufacturer.
 
I have 250mm blades for both the 80 and 100 tooth. I was thinking of going to 275mm but wasn't sure if this would make any difference.
 
Speaking as a former employee of a major power tool company, at the end of the day, the blade is mightier than the saw; the bit is mightier than the drill; etc., etc. In other words, if money is tight it's better to have a less elaborate tool and a better blade. Afford the very best blades, drill bits, router bits, etc and you will be well served.

For the Brevetti it's hard to beat Tenryu blades. So much quieter and cleaner cutting than Brevetti blades. I have three active sets to facilitate sharpening; one on the saw, one ready & waiting, and one at LA Grinding who do a terrific job of sharpening.
 
I have my sharpening guy (Jim Goings from Sharper Image) bringing in a couple pairs of Skarpaz Blades for me to try out. They are about $160 each. Any opinions on this manufacturer?
