Review on Neiko 10197A 5 Piece Titanium Drill Set by Vinay Mickel

I'd only like to buy these for a project that involves drilling about 10 holes in 18 gauge stainless steel on barrels. There are a few reviews here that they can't drill through stainless steel and the bits have been ruined when used on a barrel. But after "correct" use of these bits, they drill like high-end drill bits. Drill a pilot hole, use slower drilling speed, cooling oil and strong pressure, they will drill almost anything and last a long time. I've made 10 holes in 304L stainless steel from 7/8" to 1-1/4" and the bits are still in great shape.
