I have used quite a few industrial drill bits over the years, but none have matched the excellence of these! According to my experience, these bits are incredibly durable and can drill through a variety of tough materials with ease. The precision and accuracy of the holes are also outstanding. The ONLY downside is that they are a bit pricey, but in my opinion they are worth the investment..
