The quality I expected from Irwin. I was able to drill up to the 1 and 3/8th of an inch, definitely can go beyond. I only needed this to complete a customers request. I suggest using a good cutting oil to protect your investment. I was cutting though 1/8 inch mild steel. I have found that when it comes to a mechanics need for good bits, Irwin has never let me down.
