Based on my observations with this carbide tipped drill bit, it proves to be an efficient tool for heavy-duty industrial drilling projects. The sharpness and toughness of the bit had proven to withstand constant use without showing signs of wear.However, the diameter size may not fit all drilling needs..
Pros
Efficient and durable tool for industrial use.
Cons
Limited diameter size for specific drilling needs.
When I received the item, it was of good quality and material. It had to be sharpened to be used after a few cuts. , It could be a bit sharper, but this is a great product.
