Review on Neiko 10197A 5 Piece Titanium Drill Set by Jason Arkin

At around $3 a bit they were suspiciously cheap. I only needed them to drill two 1-3/8" holes in sheet steel, but they had a tough time even with a 1" pilot hole. They're probably fine for casual work in plastic or wood, but if you're drilling steel, even thin sheet metal, I would strongly advise against this product. After just a few seconds of drilling, the drills became blunt, bent and began to smoke. My sheet was grossly mutilated and also smoked. If you intend to use this product for precision or repetitive metal drilling, do not purchase this product.
