Just wondering how much different they are. Not looking to start a brand war, just want to know how similar the profiles are. This has probably already been answered somewhere but I can't find it.
LeeB,
The most noticable difference is in gullet depth. Performance wise, kinda like comparing apples and oranges.
Kasco 7 has tooth geometry of 7/35, very similar to the WM 7/34
A more appropriate comparison would be:
Turbo 7 or 7/39 has a deeper gullet to accomodate the steeper back angle of 39.5°
Kasco 7/40 is deeper yet. Kasco intended it mainly for high HP/production output.
Both the WM 7/39 and Kasco 7/40 want/need higher feed rates to really take advantage of the tooth profile. Lower HP machines can pull 'em, but it can be touch and go with lower torque output engines accompanied with alot of chatter and difficulty managing just how far into the governor an operator can go and still maintain good cut quality.
Hope this helps answer your question.
Thanks Richard. I really was hoping you would see this and reply. I guess I could have just asked you directly but now all of us know. Now to figure out which cam I have without being home to see it. :D
I have a 33HP diesel on my 40Wide and just can't seem to get those 7's happily humming along in wide or tough material. I guess not enough ponies.
Love the WM carbides, but WHOA the pain when I hit metal with one of them. :'(

Yes Sir. That was why I figured it was best to add a little more information.
Provided an opportunity answer common questions and provide good sound information, plus clear up some past/potential confusion. That's how we all benefit.
So, what would be the next best choice for someone liking the Turbo7's, but not quite enough power to feed at the rate required?
As I said, I'm finding that I like them, but when I get into a heavy-duty cut on my LT40 Wide, seems like I need more power to feed at the rate desired.
Considering switching my mill to electric. May remedy.
THanks.
PA,
What thickness bands are you using using on the Turbos?

I'm very interested in the performance of the 35 diesel on a Wide woodmizer. Wonder whether you've monitored RPMs in your heavy duty situations, does your engine display have a tachometer?.
I have a 38HP Diesel on my sawmill. Today I was sawing 26" wide Walnut and I had to constantly be aware of my sawing speed and the sound of the engine. That was with a new .045, 7° Turbo. Yesterday I had a .055, 7° Turbo on and I was not aware of any sawing difference.
Great info and inquiries. Yes, when I do a BIG cut, the engine groans if I feed at the rate I'd like to with 7's.
The engine DOES have a tach and I'm gonna capture it with my GoPro while cutting some BIG (max) logs today.
Yellow, I have .045 1-1/4 Turbo 7's. Been trying to mostly switch to carbide since the super-wide is the higher-value material anyway. I have some 36+ walnuts to put on there today! ;D
MM, I haven't considered a .055. Maybe that's the ticket for me...do tell more.
I find no difference in the actual cutting, but the .055 has to be more stable when you are sawing at maximum width. I suppose that you could run it duller but who wants to saw with a dull blade? The .055's do not have the blade life and seem to break more quickly than the .045's.
No one has to remind you what you have when you coil it. ;D
Wondering if someone can share a picture of the WM Turbo 7 profile. Want to make some comparisons with other similar profiles.
I suppose this is a 1-1/2" wide blade with a 7/8" pitch.
Thank you,
They make it in 1¼ also
It's my understanding that the Wood-Mizer Turbo is 7° X 39° and the Kasko is 7° X 40°. It would probably be difficult to tell them apart without other identifying characteristics.
I have discovered that .055 is a better blade for wider cuts. Also, LOTS of tension...more than WM calls for.
However, have recently gone to a Peterson Dedicated Wide Slabber and now my cuts are FLAT and straight...right tool for the big stuff. However, lot more work! :o
