About a year ago I bought a Delta 36-5152 contractor saw that is like a cadillac to me after previously having a $120.00 craftsman saw for several years. I have been getting use to the new saw ,setting it up as accurate as I feel I am good enough for at this time, using the blade that came with it. But now I am ready to get a good quality blade or 2 or 3 as future projects require, but I seem to have hit a snag on what kind of blade I can use on this saw. Delta recommends that I use a blade with a minimum kerf of .102 which I can understand because the riving knife is .087 thick But the problem is that they say that the body of the blade which I assume is the plate can be no more than .073 max. Well the only blades I have been able to find with a body that thin is the Freud thin kerf blades, but there kerf is too thin for my riving knife I like Freud products and I want to get Freud blades. Am I missing something here or is Delta trying to steer me to buying their blades?

If I read this right, they are saying to not use blades with less than a .102” kerf. Anything larger is good to go…...... Jerry (in Tucson)

This has come up a few times here…I think Delta is just being ultra conservative. The width of the teeth is the important part…the body width is nearly irrelevant. You can buy 1/8” full kerf blades that will pass by your riving knife easily, but pose greater resistance to your saw. A 3/32” thin kerf (TK) blade will be much easier on your saw’s motor (a 1/8” blade is 33% wider). The overall kerf of the cut is going to be the width of the teeth plus any runout from the blade, plus and any runout from the saw, which means if the blade is well aligned with the riving knife, most TK blades will clear the riving knife. The Irwin Marples series, Infinity, Forrest and Ridge Carbide TK, and Freud Diablo series are all very close to 0.098”, which many people have reported as working just fine with their 0.087” Delta riving knife.

Thanks fellows, I felt like it should not matter as long as the kerf is wider than the riving knife. Knotscott, I am pretty sure there will be a red thin kerf blade on my saw very soon. Glad to be a LumberJock (albeit a very green one).

Have your say...
