Based on my observations, these industrial drill bits are ineffective and wear out quickly. Although they have a sleek appearance, their performance does not live up to their appearance..
The sellers in the product description and in the picture say that for a 3 pack, Amazon will take 2 from this package and only ship one. They are probably selling the other two for extra Money on you should get what you are promised as a waste of time Good bit and therefore 2 stars Better than other drills d2 Steel like butter with butter.
