I recently bought the Forrest 90tpi chopmaster II for my miter and the Forrest 40tpi for my table saw.
It may just be me but I swear both blades are creating more dust than before. My miter I used to almost get no dust around the machine and back, but now I'm dust collection can't catch it all. I've cleared out my vacuum and such to make sure there is proper suction. Is it simply the blade chipping away a higher amount of wood to create smoother cuts?
The table saw I used to have a thin kerf and now I have a regular kerf, so I could see it throwing out more dust.
Anyone buy laserkerf? I bought one for my Bosch and It essentially covers up my dust port. Last thing I want is more dust
Just a guess, and it may depend on how many teeth the miter saw had before the 90 tooth one was installed. But the guess is that the 0 tooth is making more dust just because it has more teeth (?).
I am referencing the laser from laserkerf, not a blade.
I'm also wondering if it's throwing more chips due to the orientation of the saw blades. Before all mine were straight up and down, Forrest blades have some angled off to the sides.
as rich said the amount of wood being removed is based on the width x depth of cut the only difference would be how fine the particles are due to the type of teeth and how many teeth.i also dont use lasers for saws,not very accurate im my opinion.
I think it would be good to bring in a research scientist to: 1. study (measure) particle size and distribution, compressibility of the particles, 2. relative cost of the sawdust to the solid wood, 3. other considerations to avoid actually making something out of wood.
I wasnt trying to avoid making anything. I'm just wondering why I feel like im getting more sawdust sprayed around ad it was something I had done. Thanks though Phil
Certainly you are making the same volume of dust for the same size cut. Perhaps your new blades are sharper, leading to faster cuts, which might be overwhelming your DC.
If I was to offer a guess, I'd say one blade is producing larger bits of sawdust. Dust collection is sensitive to particle size, fine dust has different airflow requirements than coarse dust. Your DC may be on the edge of working with one size and not the other.
There are lots of variables in play. Kerf width and the type of top grind will have a significant impact, but so will the wood itself, cut speed, blade height (in a TS), etc.
It's more about the gullets on the blades. More teeth will have smaller gullets and will disperse the sawdust differently than a blade with less teeth and bigger gullets. Which size does what is hard to say because different brand blades all have different designed gullets. It's plausable that the sawdust could

My thought too. I'm thinking most blades coming with miter saws are around the 60 tooth variety. The wood getting whacked that many more times would make a finer dust, not necessarily more dust.

I don't know, but I doubt the particles are any smaller. I would think the particles are the same size, just less of them filling the gullet of each tooth. Again, it's more about how the particles are being exited from the blade, not the size of the particles. JMO
