Best blade for OSB (TS-75)

[DKurzweil]

I hope I have a problem that is as simple as a blade change, and not a more complicated issue.

I am building some shelves for my shop.  I decided to use OSB since it is cheap, sturdy, and I don't really mind the look of it.

Whenever I go to make a cut the saw cannot seem to keep up.  I sounds like it's struggling, and I feel it pulsating.  It moves forward, gets stuck, moves forward again.  It does the same thing whether I cut a single sheet at a time or multiple sheets stacked.  I know the saw should have more than enough power to make the cuts.

I am currently using the universal blade (495380).  I also have the blade for aluminum, which I think I will mount and test with tomorrow to see if it is the blade.  I also know the blade is sharp, I just got it back from the sharpeners a few weeks ago and have put very limited use onto it since.   

Do you guys think I would have better luck with a standard or panther blade?  Or could something else be out of whack?

Thanks,
Daniel

I run the stock blade in my TS75 and found osb to be a bit 'funny' as well. I am also at the limit of available power (supply) to my work areas.

Seems a bit odd to me. I use the universal blade for most everything. plywood, osb, 2x's etc. I only change out to the fine or panther for different materials. When cutting ply or osb I haven't had any problems with multiple stacks or single. Outside of the saw having an issue, the only other thing I can think of is cheap osb.
Don't know what you have in your area. Around here, think big box store, sometimes the cheap, crappy osb has some strands that stick up a bit, maybe your saw is catching on those. Try flipping the sheets over to the more rough side than the more glossy side if that makes sense for the product you have.

1st i would try the blade on a material you know is good (scrap you used before) just to make sure the sharpening is done right.
2nd make sure th esaw is on full power (i forget sometimes to put it back up)
3rd make sure the sheet isnt binding on the saw as it cuts.
4th try a cut witht he blade at full depth  to see what happens.
5th make sure the dc port isnt blacked. my ts55 was blocked and the dust was compacting in around the blade and jambing it

Let me give an update.

First, thanks for the responses. 

I played a bit in the shop this morning. 

I varied the blade speed, no difference. 
Material isn't binding, and the saw isn't clogged.
I cut down a piece of pine 1 by material.  No problems
Cut down 3/4 inch MDF.  No problems
I tried a scrap piece of OSB from a few month ago.  Same problem, but not as bad. 

So it must be the material that is causing the problems. 

My next question is, I think a standard blade (495379) will be a bit more aggressive, resulting in less hang up, but still give a decent cut.  Am I correct in my thinking here?

definetly try a rougher blade. maybe the blade isnt aggressive enough

I just tried this using the TS75 (speed 4), the universal blade (moderately used, never sharpened) and the CT2 on maximum.

I only had 1/4" OSB so I doubled it to make 1/2".

I didn't detect any slowdowns, pulsing or other problems.

But OSB and similar products contain a lot of glue, and who knows what proportions or formula is found in a particular piece.  It is a very useful material but I suspect it is not good for blades.

I can cut multiple 15/32" sheets of OSB with my ts55 and a 28 tooth Tenryu blade. No slowing, it's actually the speed of the cut that makes using a TS for sheathing worthwhile.

I get a bit of fuzzing on the bottom side of the bottom sheet, the top of the cut is clean even without a splinter guard.  I also use the Tenryu blade for Smartside OSB siding and soffit. The SS is much denser than typical OSB but the TS55 has no problem plowing through it.

I will try my 48 tooth blade today and see how it works.

 

[Kevin Stricker]

Ripped 1 5/8" of OSB( 1/2" OSB sheathing, 3/8" SS, and 3/4" SS trim sandwich) with my well used 48 tooth universal blade with no problems.  Seems strange your TS 75 would have problems cutting a single sheet.

As for the comments about cheap OSB, I doubt there really is such an animal.  LP is the biggest manufacturer of OSB products, and they stock both  the big box and lumber yards around here.  It is possible you have some that was sitting outside and got saturated though.  My first thought was that you are cutting into a warped panel that was not properly supported, but I'm sure you already thought of that.

Good luck.

Seems to me the toe-in of the saw may be out a bit. The sticking/starting in the cut is a symptom but you would expect to see it on other materials.
