Hi all,

I am planning on doing work on mostly furniture pieces (i.e., plans such as found @ Ana-White), and before I get started I figured I would replace the older blade in the circular saw (the saw, which works perfectly fine was passed down to me with a fairly used 24T blade).  As it is my first time purchasing a blade, I am curious what tooth size I should look for.  I could very well be wrong, but I am assuming that a higher tooth count would be helpful for cutting wood to be used in furniture pieces as higher tooth count provides finer/smoother cuts, right?

From what I was able to find online it seems maybe a 40T or 60T would be good?  And carbide-tipped as well?

And I'm sure I would be doing some combination of cross-cutting and ripping at some point, so a combination or compromise blade of some sort is probably what I'm looking for.

Any ideas?

Well I want to apologize.  I just realized I pretty much hijacked this thread.  Hopefully the info was of some help to the original author.  

Just a comment on saw blade selection in general. Generally dedicated rip blades are in the 20 to 30 tooth range. Dedicated crosscut blades are in the 60 to 80 tooth range. Why??

The ripping process is done with the grain which results in long wood fibers being rolled up into fairly large chips. These require a larger gullet to clear. Larger gullets equal needing more space between the teeth, hence, fewer teeth. Crosscutting, on the other hand results in the fibers being roughly equal to the saw kerf or much smaller allowing for smaller gullets and more teeth.

The 40 to 50 tooth blades are generally referred to as Combination blades which will do an acceptable job on both ripping and crosscutting but, with a couple of exceptions, don't do a top notch job at either.

There are a lot of other contributing factors to saw blade selection such as grind; HiATB, ATB, TCG, FT, etc. There is also the hook angle, a measure of how aggressive the blade is, that needs to be considered.

i use the bosch dare devil blades i use an 80 tooth i believe, very smooth cuts, under 40$ at the time. i have used the diablo blades as well and no complaints there either although i mostly used them in the circular saw so i cant comment on the 10 or 12 inch blades

Additional info:

Blade diameter---RPM---SFM

 

Table saw “A”-- motor 5000rpm.

SFM:

10” blade 13,080

7-1/4” blade 9,420

 

Table saw “B”-- motor 3600 rpm.

SFM:

10” blade 9,400

7-1/4” blade  6,830

 

NOTE:

SFM is the same a 7.25” blade in a saw running at 5000rpm and 

a 10” blade in a saw running at 3600rpm.

Rick....no worry for the hijacking...I got all the info I needed.  I went with the Diablo 40T from Home Depot.  Worked well on rips and cross cuts on pine lumber.  I am a happy camper - my project this weekend worked out well.

I ordered a diablo 40 and 60 tooth blade.  If the Dewalt 24 tooth blade that comes with my D745 saw will not suffice for construction grade work I will replace it.  

ok I think I have my blade bases covered .  I have a 40T and 60T in 7.25 inch for my circular and miter saws.  I have a 24T, 40T, 60T  in 10 inch for my Table saw.  All are Diablo blades.

I have had the ACS for about a year.  Was wondering if there any other blades, like a Diablo, that will fit the saw?Continue

New Kreg 720Pro

I saw the video Kreg put out for this new jig and had high hopes for it.

I purchased one today and am very disappointed with it.

First the docking station is extremely cheap. The plastic is pathetic. A Lego has more…
