Dull and Defective Industrial Drill Bit

As a new buyer, I was extremely disappointed with this Industrial and Scientific product. As a result of my tests, I determined that the drill bit is extremely dull and defective. It has made drilling into even the softest materials a task that is impossible to accomplish in a timely manner. The only positive aspect of this drill bit is its length. The biggest con is that it does not live up to its own specification. I wouldn't recommend this product to anyone in the industry.

Pros
  • High quality stainless steel material
Cons
  • Not suitable for smaller jobs or tight spaces due to its length

Poor results, dull seam

I used these for drilling holes in old bed frames made from stamped/forged angles. They don't work very well. Once I managed to partially drill open a broken faucet. They just don't bite the metal

Pros
  • Twist drill bit
Cons
  • No instructions
