Topic tags/keywords: riving knife kerf plate size question tablesaw

Hi,
I am looking at replacing the stock 10” blade that came with my table saw and I am wondering if my riving knife is the right thickness for the blade I want to purchase. The blade I am looking at has a kerf of 0.126” and a plate size is 0.098”. My riving knife is 2.5mm (0.098”) which is the same as the plate size. I have searched numerous resources on the web and everyone seems to say the riving knife thickness must be GREATER than the blade thickness (plate size) and less than the kerf. If my riving knife is EQUAL to the blade size will it still offer kickback protection? In case anyone wonders I am looking at the Freud P410 blade. Any feedback is appreciated…
Thanks,
Colin

Yes it will offer the same protection from kickback. It ideal if it slightly less than the thickness but never thicker than the blade kerf cut.

The blade thickness should be at least =/> than the RK so the kerf is wide enough to pass by the RK. If the RK thickness is greater than the blade thickness, then the workpiece will bind on the RK. So essentially the blade you’re looking at will work OK. Most TK blades are in the 0.98” range (3/32”), and most RK’s have a slight taper at the front, so most standard 3/32” TK blades should also work.
