Customer Reviews
Rated 1 out of 5 by from I just don'tunderstand it. I have two of the Irwin Classic 7-1/4" 140 Tooth blades that are useless. The first one I used 2 or 3 yeras ago to build a work bench with OSB top and shelves. I probably cut a total of 16 feet of 7/16" OSB before it gave out. I thought I had done something wrong so I let it go at that. Then recntly I needed to cut some more 7/16 " OSB and the first 8 foot rip went great. I got about 18" into the second rip when the blade went dull and started cutting crooked. I smoked my way through the cut and looked for a reason why this happedned. I couldn't find one. I put the Makita combination blade that came with my saw and cut another 16 feet with ease. The Makita blade has cut hundeds of feet of wood. I now know that it is unnecessary to use a fine tooth blade to cut OSB for my purposes.
