Nice drill bits for what I needed them for. I used them to drill out orifices to convert ovens from LP to Natural Gas

Don't buy. Junk drill bits.
Pure junk. Drill bits won't even start at home in stainless steel as advertised. Might as well be made of lead. Don't waste your money on this trash.

Good drill bits
Well worth the money, I was suspicious because these were cheap but I needed them quickly. Drilled 4140 round tube with it, and it drilled perfectly and didn't "grab" when it went through. Sign of decent cobalt metal the drill was made of and an accurate grind. Will buy more of this brand
