All the Milwaukee blades I’ve used have failed at the weld , it doesn’t mater how durable the teeth are if the blade snapsMilwaunkee blades are made from good cobalt HSS, so durability is good. Problem was for most the weld joint on most packs was done pssed so they kick every time the joint goes round. I dont know if they are still the same but, while unpleasant, they are useable. I might risk another pack as they are much cheaper.
The biggest problem I have found is the blades don't last very long - I've been using Milwaukee blades on mine and they tend to crack and fracture rather than wear out.
They aren't cracking on the rear edge are they?
