Title: This saw blade does not hold up.
Product review: As a point of reference, I have used several 7-1/4" aluminum cutting blades before in building my 49' aluminum sailboat. They have all held up well, but eventually dulled (as expected). I only used this blade for cutting staight sections of 3/8" aluminum in a cutting fixture (previous blades had been used exactly the same way and often a lot harder). No side loads or free hand cutting at all. The first three cuts were very fine and clean. On the fourth cut the blade self destructed, losing several carbides and teeth. I would not recommend this blade for anyone cutting anything thicker than 1/8", if that.
Would you say this review depicts the product in a flattering or unflattering light?
