Query: Fein Multimaster E-Cut Combo Kit (3 Pack)

The Wood Holz Precision blade (the wide one) with the larger teeth is not acceptable. The first time that I used it, about ten of the teeth broke off, and the next time, another 10-15 teeth broke off. I was only cutting douglas fir and there were absolutely no nails in the wood. The blade was useless after just using it three times (only about 1/2" of teeth remained). The other blades seem to be durable.
