This set has proven to be extremely versatile and durable. The ability to drill and tap in one step has saved me a lot of time and effort, and the set has performed flawlessly on a variety of materials. The Punch Tool was very useful as well. I highly recommend.

snapped and broke! terribleThis item was a waste of money. Despite being marketed as having great construction and build quality, it was not up to par. It did not hold up well under heavy use, and it was not worth the price. I cannot recommend this item to anyone in need of a dependable product. This is an honest, unpaid review.

These bits shattered on mild steel, Very low pressure and less than enough to drive them into the steelGreat Idea but fails miserably. I suspect that often folks would shatter a 1/4-20 normal tap and it has much more metal.
