The packaging is poor, all parts are taken out of the boxes and hanging in the envelope. Bit life was less than 1/6 inch when using cutting fluid. This is not HSS! I ended up using an old and real HSS bit that I found in my old editing toolbox and it dates back to the 90's. This drill bit made 3/4" thick steel that I had to drill through. I think I should dig first before buying this junk. Never waste your money again unless you're drilling in soft metal.
