I love Freud's Beats and have been using them for quite some time. You can get a bad one from time to time, but they are mostly of the highest quality. All I can say is use them properly and for their intended purpose. And they should last a long time. We clean them with a brush after each use in the store and take care of them like children. Some call it overkill but ask me that after over a year of daily use it's not all overkill. Clean your bits and they'll last a lot longer!
