Review on Neiko 10197A 5 Piece Titanium Drill Set by Daniel Robinson

The bit cannot be cut. I needed a large 1" drill bit to drill through my car's firewall for the car audio power cable. The bit is not sharp and will not cut. It barely enlarged the hole I had already made with another 3/4 diameter drill bit. The drill bit itself was already starting to discolor and was struggling to cut into the flimsy sheet metal, which my other 3/4 bit cut through with ease. Complete disappointment. Don't buy this junk. FYI if you want a good set, my other set that cut through the firewall like butter was the QWORK brand. This brand Neiko is worth nothing. Buyer Warning.
