<p>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. </p>

<p>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. </p>

<p>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.</p>

<p>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</p>

<p>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??</p>
<p>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…</p>

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.</p>
<p>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.</p>
<p>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.</p> Well I want to apologize.

<p>Hi Rick, You are correct about the zero clearance throat plates. However I never use saw blades other that the 10 inch but making a zero clearance throat plate is standard procedure for me. I make one for all the heights that I cut so that it is a true zero clearance plate. I get better cuts doing it this way. Since I also use the table saw for doing a variety of operations I also make special throat plates for them as well. </p>

<p>I think the way I will go is a 40 tooth rip blade in 7.25 a 80 t crosscut finishing blade 7.25 and make zero clearance throat plates for both. The 24 tooth blade that comes with the saw will be researved for construction grade materials like decking maybe? Does this make sense to everone.?</p>

<p>I use both the 40t and 60t Diablo blades from the Home Depot, I use them for breaking down the bigger sheets of plywood to more manageable pcs. for the table saw. I work in my basement so getting a 4x8 sheet of plywood down there is close to impossible, The combination 40t blade does a really good job with very little splintering. If I iwas only to use one blade I would get the 40t one.</p>
