Table Saw Blade Question
Hello,
Curious as to why my 8" rotary table saw blade has 3 notches cut in the periphery. They go down toward the center perhaps 30 % or so of the radius. Any idea why they put these notches / slots into the blade ? B. |

If they were not there when the blade heated up, especially when cutting hardwood, the blade would warp, causing it to at a minimum cut a wider kerf, and possibly collide with the sides of the blade slot. The notches allow the major portion of the blade to be broken up into segments, and eac segment is able to expand as necessary without warping the blade. If you want to see for yourself how hot a blade can get, cut some scrap hardwood or plywood for a few minutes, turn the saw off, and once the blade stops spinning touch it and see how warm it is. Expand that to maybe ten or fifteen minutes at a time of cutting and you can extrapolate how hot it would get. |
